-
-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

+Description: Upstream changes introduced in version 1.10.2.1-1
+ This patch has been created by dpkg-source during the package build.
+ Here's the last changelog entry, hopefully it gives details on why
+ those changes were made:
+ .
+ mathgl (1.10.2.1-1) UNRELEASED; urgency=low
+ .
+ [ D Eftaxiopoulos ]
+ * Update to Debian Policy 3.9.1.0.
+ * Put myself and D. Haley to the maintainers list.
+ * Comment out parallel-build-png.patch in the debian/patches/series file
+ since it seems to apply to a texinfo/Makefile.am file that is not
+ included in the source tree.
+ * Append package quilt to the build-depends list for the source in the
+ debian/control file, in order to fix a lintian error.
+ * Reinstate debian/source/format file with content '3.0 (quilt)'.
+ * Fix Lintian warnings related to manpages.
+ .
+ [ D Haley ]
+ * New upstream release 1.10.2.1 (Closes: #562743).
+ .
+ [ Salvatore Bonaccorso ]
+ * New Maintainer (Closes: #564422). Set Maintainer to Debian Science
+ Maintainers <debian-science-maintainers at lists.alioth.debian.org>.
+ * Convert to '3.0 (quilt)' package source format. Drop quilt framework for
+ packaging.
+ * debian/control:
+ - Change Vcs-Browser and Vcs-Git to the debian-science git repository.
+ - Change Section for source package to 'science' as per debian-science
+ group policy.
+ - Set DM-Upload-Allowed field to yes.
+ * Add myself to Uploaders.
+ .
+ The person named in the Author field signed this changelog entry.

+-# These exist entirely to fool aclocal when bootstrapping libtool.
+-#
+-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+-# which have later been changed to m4_define as they aren't part of the
+-# exported API, or moved to Autoconf or Automake where they belong.
+-#
+-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+-# using a macro with the same name in our local m4/libtool.m4 it'll
+-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+-# and doesn't know about Autoconf macros at all.)
+-#
+-# So we provide this file, which has a silly filename so it's always
+-# included after everything else. This provides aclocal with the
+-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+-# because those macros already exist, or will be overwritten later.
+-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+-#
+-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+-# Yes, that means every name once taken will need to remain here until
+-# we give up compatibility with versions before 1.7, at which point

++ at chapter Samples
++
++This chapter contain a lot of sample codes for all types of plots and for most important examples and hints. The same sample (with pictures) you can find at @uref{http://mathgl.sf.net/pictures.html}. Most of examples have the sample code on 5 languages: C++, MGL, C, Fortran and Python. However, I put only C++ code for some of examples due to a lot of them and clearency how to write code for other languages. All samples are divided on 6 large categories.
++
++The minimal code to view the samples for different languages are following.
++
++ at strong{C++ code}
++
++For compilation use: @code{g++ -o sample sample.cpp -lmgl}.
++ at verbatim
++#include <mgl/mgl_zb.h>
++int main()
++{
++ mglGraph *gr = new mglGraphZB;
++ //~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
++ // put sample code here
++ //~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
++ gr->ShowImage(); delete gr;
++ return 0;
++}
++ at end verbatim
++ at strong{MGL code}
++
++For preview use: @code{mglview sample.mgl}.
++ at verbatim
++#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
++# put sample code here
++# --> you may use sample as is :)
++#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
++ at end verbatim
++ at strong{Pure C code}
++
++For compilation use: @code{gcc -o sample sample.c -lmgl}.
++ at verbatim
++#include <mgl/mgl_c.h>
++int main()
++{
++ HMGL gr = mgl_create_graph_zb(600,400);
++ /*~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*/
++ /* put sample code here */
++ /*~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*/
++ mgl_show_image(gr,"",0);
++ mgl_delete_graph(gr);
++ return 0;
++}
++ at end verbatim
++ at strong{Fortran code}
++
++For compilation use: @code{gfortran -o sample sample.f90 -lmgl}. Note, fortran don't have argument checking. So you have to take special attention to pass real variables to real arguments of functions and integer variables to integer arguments of functions. There is no other special checking for that!!!

++MathGL library can be used by several manners. Each has positive and negative sides:
++ at itemize @bullet
++ at item
++ at emph{The using of MathGL library features for creating graphical window (requires FLTK or GLUT libraries).}
++
++Positive side is the possibility to view the plot at once and to modify it (rotate, zoom or switch on transparency or lighting) by hand or by mouse. Negative sides are: the need of X-terminal and limitation consisting in working with the only one set of data at a time.
++ at item
++ at emph{Direct writing to file in bitmap or vector format without creation of graphical window.}
++
++Positive aspects are: batch processing of similar data set (for example, a set of resulting data files for different calculation parameters), running from the console program (including the cluster calculation), fast and automated drawing, saving pictures for further analysis (or demonstration). Negative sides are: the usage of the external program for picture viewing. Also, the data plotting is non-visual. So, you have to imagine the picture (view angles, lighting and so on) before the plotting. I recommend to use graphical window for determining the optimal parameters of plotting on the base of some typical data set. And later use these parameters for batch processing in console program.
++ at item
++ at emph{Drawing in memory with the following displaying by other graphical program.}
++
++In this case the programmer has more freedom in selecting the window libraries (not only FLTK or GLUT), in positioning and surroundings control and so on. I recommend to use such way for ``settled'' programs.
++ at end itemize
++
++Let me consider the aforesaid in more detail.
++

++* Using FLTK/GLUT window::
++* Drawing to file::
++* Drawing in memory::
++* Using QMathGL::
++ at end menu
++
++
++ at c ------------------------------------------------------------------
++ at node Using FLTK/GLUT window, Drawing to file, , Basic usage
++ at subsection Using FLTK/GLUT window
++ at cindex window
++ at cindex widgets
++
++The ``interactive'' way of drawing in MathGL consists in window creation with help of class @code{mglGraphGLUT} or @code{mglGraphGLUT} (@pxref{Widget classes}) and the following drawing in this window. There is a corresponding code:
++ at verbatim
++ int sample(mglGraph *gr, void *)
++ {
++ gr->Rotate(60,40);
++ gr->Box();
++ return 0;
++ }
++ //-----------------------------------------------------
++ int main(int argc,char **argv)
++ {
++ mglGraphFLTK gr;
++ gr.Window(argc,argv,sample,"MathGL examples");
++ return mglFlRun();
++ }
++ at end verbatim
++Here function @code{sample} is defined. This function does all drawing. Other function @code{main} is entry point function for console program. Arguments of @code{main} should be transfered to @code{Window()} since it may contain OS specific information (@pxref{mglGraphAB class}).
++
++Alternatively you can create yours own class inherited from class @code{mglDraw} and reimplement the function @code{Draw()} in it:
++ at verbatim
++ class Foo : public mglDraw
++ {
++ public:
++ int Draw(mglGraph *gr);
++ } foo;
++ //-----------------------------------------------------
++ int Foo::Draw(mglGraph *gr)
++ {
++ gr->Rotate(60,40);
++ gr->Box();
++ return 0;
++ }
++ //-----------------------------------------------------
++ int main(int argc,char **argv)
++ {
++ mglGraphFLTK gr;
++ gr.Window(argc,argv,foo,"MathGL examples");
++ return mglFlRun();
++ }
++ at end verbatim
++
++The similar code can be written for @code{mglGraphGLUT} or for @code{mglGraphQT} window (function @code{sample()} is the same):
++ at verbatim
++ int main(int argc,char **argv)
++ {
++ mglGraphGLUT gr;
++ gr.Window(argc,argv,sample,"MathGL examples");
++ return 0;
++ }
++ at end verbatim
++
++The rotation, shift, zooming, switching on/off transparency and lighting can be done with help of tool-buttons (for @code{mglGraphFLTK} and @code{mglGraphQT}) or by hot-keys: @samp{a}, @samp{d}, @samp{w}, @samp{s} for plot rotation, @samp{r} and @samp{f} switching on/off transparency and lighting. Press @samp{x} for exit (or closing the window).
++
++In this example function @code{sample} rotates axes (@code{Rotate()}, @pxref{Transformation matrix}) and draws the bounding box (@code{Box()}). Drawing procedure is separated in a function since it will be used on demand when window canvas needs to be redrawn. Widget classes (@code{mglGraphFLTK}, @code{mglGraphGLUT} and so on) support a delayed drawing, when all plotting functions are called once at the beginning of writing to memory lists. Further program displays the saved lists faster. Resulting redrawing will be faster but it requires sufficient memory. Several lists (frames) can be displayed one after another (by pressing @samp{,}, @samp{.}) or run as cinema. To switch these feature on one needs to modify function @code{sample}:
++ at verbatim
++ int sample1(mglGraph *gr, void *)
++ {
++ gr->NewFrame(); // the first frame
++ gr->Rotate(60,40);
++ gr->Box();
++ gr->EndFrame(); // end of the first frame
++ gr->NewFrame(); // the second frame
++ gr->Box();
++ gr->Axis("xy");
++ gr->EndFrame(); // end of the second frame
++ return GetNumFrame(); // returns the frame number
++ }
++ at end verbatim
++First, the function creates a frame @code{NewFrame()} for rotated axes and draws the bounding box. After the frame drawing the function @code{EndFrame()} @strong{must be} called! The second frame contains the bounding box and axes @code{Axis("xy")} in the initial (unrotated) coordinates. Function @code{sample} returns the number of created frames @code{GetNumFrame()}.
++
++ at c ------------------------------------------------------------------
++ at node Drawing to file, Drawing in memory, Using FLTK/GLUT window, Basic usage
++ at subsection Drawing to file
++
++Another way of using MathGL library is the direct picture writing to file. It is most usable for plot creating during calculation or for using of small programs (like Matlab or Scilab scripts) for visualizing repetitive sets of data. But the speed of drawing is much higher in comparison with a script language. There are two classes for exporting in file: class @code{mglGraphZB} saves in bitmap format (like PNG), @code{mglGraphPS} saves in vector PostScript format (@pxref{Plotter classes}).
++
++The following code produces a bitmap PNG picture:
++ at verbatim
++ int main(int ,char **)
++ {
++ mglGraphZB gr;
++ gr.Alpha(true);
++ gr.Light(true); gr.Light(0,mglPoint(1,0,-1));
++ sample(&gr,NULL); // The same drawing function.
++ gr.WritePNG("test.png"); // Don't forget to save the result!
++ return 0;
++ }
++ at end verbatim
++The only difference from the previous (using windows) variant is manual switching the transparency @code{Alpha} and lightning @code{Light} on, if the plot requires it. The using of frames is not advisable since the whole image is prepared each time. If function @code{sample} contains frames then each frame will be saved to a separate file. In principle, one does not need to separate drawing functions in case of direct file writing in consequence of the single calling of this function for each picture. However, one may use the same drawing procedure to create a plot with changed parameters, to export in different file types, to emphasize the drawing code and so on. So, in future I will put the drawing in separate function.
++
++The code for export in vector EPS file looks the same:
++ at verbatim
++ int main(int ,char **)
++ {
++ mglGraphPS gr;
++ gr.Light(true); gr.Light(0,mglPoint(1,0,-1));
++ sample(&gr,NULL); // The same drawing function.
++ gr.WriteEPS("test.eps"); // Don't forget to save the result!
++ return 0;
++ }
++ at end verbatim
++The differences from the using of bitmap picture are: applying of the other class @code{mglGraphPS}, and writing to other format (function @code{WriteEPS()} instead of function @code{WritePNG()}). Moreover, there is no switching of the plot transparency @code{Alpha} since EPS format does not support it. Possibly I shall include transparency in future by program emulation.
++
++Classes @code{mglGraphZB} and @code{mglGraphPS} have some merits and demerits. Class @code{mglGraphZB} draws beautiful surface with transparency, smoothed colors and lightning, but the output picture is @emph{bitmap}, that leads to a bad scalability. On the contrary, class @code{mglGraphPS} creates vector file with excellent scalability. But file has large size (especially for surfaces), it does not support transparency and color smoothing. So, vector picture looks stylish but a bit angularly.
++
++ at c ------------------------------------------------------------------
++ at node Drawing in memory, Using QMathGL, Drawing to file, Basic usage
++ at subsection Drawing in memory
++
++The last way of MathGL using is the drawing in memory. Class @code{mglGraphZB} allows one to create a bitmap picture in memory. Further this picture can be displayed in window by some window libraries (like wxWidgets, FLTK, Windows GDI and so on). For example, the code for drawing in wxWidget library looks like:
++ at verbatim
++ void MyForm::OnPaint(wxPaintEvent& event)
++ {
++ int w,h,x,y;
++ GetClientSize(&w,&h); // size of the picture
++ mglGraphZB gr(w,h);
++
++ gr.Alpha(true); // draws something using MathGL
++ gr.Light(true); gr.Light(0,mglPoint(1,0,-1));
++ sample(&gr,NULL);
++
++ wxImage img(w,h,gr.GetBits(),true);
++ ToolBar->GetSize(&x,&y); // gets a height of the toolbar if any
++ wxPaintDC dc(this); // and draws it
++ dc.DrawBitmap(wxBitmap(img),0,y);
++ }
++ at end verbatim
++The drawing in other libraries is most the same. Moreover, I excluded the support of TIFF and JPEG files from MathGL by default for compatibility with wxWidgets library.
++
++ at c ------------------------------------------------------------------
++ at node Using QMathGL, , Drawing in memory, Basic usage
++ at subsection Using QMathGL
++
++MathGL have several interface widgets for different widget libraries. There are QMathGL for Qt, Fl_MathGL for FLTK in MathGL v.1.8. These classes provide control which display MathGL graphics. Unfortunately there is no uniform interface for widget classes because all libraries have slightly different set of functions, features and so on. However the usage of MathGL widgets is rather simple. Let me show it on the example of QMathGL.
++
++First of all you have to define the drawing function or inherit a class from @code{mglDraw} class. After it just create a window and setup QMathGL instance as any other Qt widget:
++ at verbatim
++ int main(int argc,char **argv)
++ {
++ QApplication a(argc,argv);
++ QMainWindow *Wnd = new QMainWindow;
++ Wnd->resize(650,480); // for fill up the QMGL, menu and toolbars
++ Wnd->setWindowTitle(title);
++ // here I allow to scroll QMathGL -- the case
++ // then user want to prepare huge picture
++ QScrollArea *scroll = new QScrollArea(Wnd);
++
++ // Create and setup QMathGL
++ QMathGL *QMGL = new QMathGL(Wnd);
++ QMGL->setPopup(popup); // if you want to setup popup menu for QMGL
++ QMGL->setDraw(sample, NULL);
++ // or use QMGL->setDraw(foo); for instance of class Foo:public mglDraw
++ QMGL->update();
++
++ // continue other setup (menu, toolbar and so on)
++ makeMenu();
++ scroll->setWidget(QMGL);
++ Wnd->setCentralWidget(scroll);
++ Wnd->show();
++ return a.exec();
++ }
++ at end verbatim

++
++Now I show several non-obvious features of MathGL: several subplots in a single picture, curvilinear coordinates, text printing and so on. Generally you may miss this section at first reading, but I don't recommend it.

++
++Let me demonstrate possibilities of axes transformation. MathGL has the following functions: @code{SubPlot}, @code{InPlot}, @code{Aspect} and @code{Rotate} (@pxref{Transformation matrix}). The order of their calling is strictly determined. First, one changes the position of axes in image area (functions @code{SubPlot} and @code{InPlot}). After that one may rotate the plot (function @code{Rotate}). Finally, one may change aspects of axes (function @code{Aspect}). The following code illustrates the aforesaid it:
++ at verbatim
++ int sample(mglGraph *gr, void *)
++ {
++ gr->SubPlot(2,2,0);
++ gr->Box();
++ gr->Puts(mglPoint(-1,1.1,1),"Just box","rL");
++ gr->InPlot(0.2,0.5,0.7,1);
++ gr->Box();
++ gr->Puts(mglPoint(0,1.2,1),"InPlot example");
++

++
++MathGL library can draw not only the bounding box but also the axes, grids, labels and so on. The limits of axes and their origin (the point of intersection) are determined by function @code{Axis()}. Also you can use @code{XRange(), YRange(), ZRange()} functions (@pxref{Ranges (bounding box)}). Ticks on axis are specified by function @code{SetTicks} (@pxref{Ticks}). First argument the direction for each change will be applied. Second argument gives the step between ticks (if positive) or gives the number of ticks on the axis (if negative) or set to use logarithmic ticks (if zero). Third argument gives numbers of sub-ticks between ticks (default is zero). Last argument define the initial ticks position.
++
++Function @code{Axis} draws axes. Its textual string shows in which directions the axis or axes will be drawn (by default @code{"xyz"}, function draws axes in all directions). Function @code{Grid} draws grid perpendicularly to specified directions. Example of axes and grid drawing is:
++ at verbatim
++ int sample(mglGraph *gr, void *)
++ {
++ gr->SubPlot(2,2,0);
++ gr->SetTicks('x', 0.4, 3); // sets tick step to 0.5
++ gr->SetTicks('y', 0.4, 3); // and draws 3 subticks
++ gr->Box(); // should be after the ticks change
++ gr->Axis("xy");
++ gr->Grid();
++ gr->Puts(mglPoint(0,1.3,1),"Axis and grid");
++
++ gr->SetTicks('x'); gr->SetTicks('y'); // restore back
++ gr->Axis(mglPoint(-1,-1,-1),mglPoint(1,1,1),mglPoint(0,0,0));
++
++ gr->SubPlot(2,2,1);
++ gr->Rotate(60,40);
++ gr->Axis();
++ gr->Label('x',"x");
++ gr->Label('y',"y");
++ gr->Label('z',"z");
++ gr->Puts(mglPoint(0,0,1.5),"Axis and labels");
++
++ gr->SubPlot(2,2,2);
++ gr->Rotate(60,40);
++ gr->SetTicks('x', 0.2); gr->SetTicks('y', 0.2);
++ gr->SetTicks('z', 0.2); // too low step of ticks
++ gr->Axis(mglPoint(-1,-1,-1),mglPoint(1,1,1),mglPoint(-1,-1,-1));
++ gr->Axis();
++ gr->Grid();
++ gr->Puts(mglPoint(0,0,1.5),"Shift origin and add grid");
++ gr->Puts(mglPoint(0,0,1.2),"(note, too many ticks)");
++
++ gr->SubPlot(2,2,3);
++ gr->Rotate(60,40);
++ gr->SetTicks('x', -6); // decrease the number of ticks
++ gr->SetTicks('y', -6);
++ gr->Axis("yz");
++ gr->Label('y',"Y axis",0);
++ gr->Label('z',"Z axis",0);
++ gr->Puts(mglPoint(0,0,1.5),"Remove X axis, and");
++ gr->Puts(mglPoint(0,0,1.2),"decrease number of ticks");
++ return 0;
++ }
++ at end verbatim
++
++This example shows the importance of the correct choosing of the number of ticks on axis. If tick step is too small then its text may overlap and becomes unreadable. This code has the example of @code{Label} function. It draws label for axis in specified direction. The text position on axis is specified by third argument of @code{Label} function. If it is positive then then text is drawn near the axis maximum, if negative then the same takes place near the minimum of axis, if zero - then at the center of axis.

++MathGL prints text by vector font. There are functions for manual specifying of text position (like @code{Puts}) and for its automatic selection (like @code{Label}, @code{Legend} and so on). MathGL prints text always in specified position even if it lies outside the bounding box. The default size of font is specified by variables @var{FontSize} (@pxref{Font settings}). However, the actual size of output string depends on position of axes (depends on functions @code{SubPlot}, @code{InPlot}). The switching of the font style (italic, bold, wire and so on) can be done for the whole string (by function parameter) or inside the string. By default MathGL parses TeX-like commands for symbols and indexes (see @pxref{mglFont class}). Example of MathGL font drawing is:
++ at verbatim
++ int sample(mglGraph *gr, void *)
++ {
++ setlocale(LC_CTYPE, "ru_RU.cp1251");
++ gr->Puts(mglPoint(0,1),"Text can be in ASCII and in Unicode");

++ at node Animation, , Text printing example, Advanced usage
++ at subsection Animation
++
++You can make animation by several methods in MathGL: by export in animated GIF, or by save each frame in separate file (usually JPEG) and convert these files into movie. Let me show both methods.
++
++The simplest methods is making animated GIF. There are 3 steps: (1) open GIF file by @code{StartGIF()} function; (2) create the frames by calling @code{NewFrame()} before and @code{EndFrame()} after plotting; (3) close GIF by @code{CloseGIF()} function. So the simplest code for ``running'' sinusoid will look like this:
++ at verbatim
++ int sample(mglGraph *gr, void *)
++ {
++ mglData dat(100);
++ char str[32];
++ gr->StartGIF("sample.gif");
++ for(int i=0;i<100;i++)
++ {
++ gr->NewFrame(); // start frame
++ gr->Box(); // some plotting
++ sprintf(str,"sin(pi*x+%g*pi)",0.02*i);
++ dat.Modify(str);
++ gr->Plot(dat,"b");
++ gr->EndFrame(); // end frame
++ }
++ gr->CloseGIF();
++ return 0;
++ }
++ at end verbatim
++
++The second way is saving each frame in separate file (usually JPEG) and later make the movie from them. MathGL have special function for saving frames -- it is @code{WriteFrame()}. This function save each frame with automatic name @samp{frame0001.jpg, frame0002.jpg} and so on. Here prefix @samp{frame} is defined by @var{PlotId} variable of @code{mglGraph} class. So the similar code will look like this:
++ at verbatim
++ int sample(mglGraph *gr, void *)
++ {
++ mglData dat(100);
++ char str[32];
++ for(int i=0;i<100;i++)
++ {
++ gr->NewFrame(); // start frame
++ gr->Box(); // some plotting
++ sprintf(str,"sin(pi*x+%g*pi)",0.02*i);
++ dat.Modify(str);
++ gr->Plot(dat,"b");
++ gr->EndFrame(); // end frame
++ gr->WriteFrame(); // save frame
++ }
++ return 0;
++ }
++ at end verbatim
++
++Created files can be converted to movie by help of a lot of programs. For example, you can use ImageMagic (command @samp{convert frame*.jpg movie.mpg}), MPEG library, GIMP and so on.
++
++Finally, you can use @code{mgl2gif} tool for doing the same with MGL scripts (@pxref{Utilities}).

++
++Class @code{mglData} contains all functions for the data handling in MathGL (@pxref{mglData class}). There are several matters why I use class @code{mglData} but not a single array: it does not depend on type of data (float or double), sizes of data arrays are kept with data, memory working is simpler and safer.
++
++ at menu
++* Array creation::
++* Data changing::
++ at end menu
++
++ at c ------------------------------------------------------------------
++ at node Array creation, Data changing, , Data handling
++ at subsection Array creation
++
++One can put the data in @code{mglData} instance by several ways. Let us do it for sinus function:
++ at itemize @bullet
++ at item
++one can create external array, fill it and put to @code{mglData} variable
++ at verbatim
++ double *a = new double[50];
++ for(int i=0;i<50;i++) a[i] = sin(M_PI*i/49.);
++
++ mglData y;
++ y.Set(a,50);
++ at end verbatim
++
++ at item
++another way is to create @code{mglData} instance of the desired size and then to work directly with data in this variable
++ at verbatim
++ mglData y(50);
++ for(int i=0;i<50;i++) y.a[i] = sin(M_PI*i/49.);
++ at end verbatim
++
++ at item
++next way is to fill the data in @code{mglData} instance by textual formula with the help of @code{Modify()} function
++ at verbatim
++ mglData y(50);
++ y.Modify("sin(pi*x)");
++ at end verbatim
++
++ at item
++or one may fill the array in some interval and modify it later
++ at verbatim
++ mglData y(50);
++ y.Fill(0,M_PI);
++ y.Modify("sin(u)");
++ at end verbatim
++
++ at item
++finally it can be loaded from file
++ at verbatim
++ FILE *fp=fopen("sin.dat","wt"); // create file first
++ for(int i=0;i<50;i++) fprintf(fp,"%g\n",sin(M_PI*i/49.));
++ fclose(fp);
++
++ mglData y("sin.dat"); // load it
++ at end verbatim
++
++ at item
++at this one can read only part of data
++ at verbatim
++ FILE *fp-fopen("sin.dat","wt"); // create large file first
++ for(int i=0;i<70;i++) fprintf(fp,"%g\n",sin(M_PI*i/49.));
++ fclose(fp);
++
++ mglData y;
++ y.Read("sin.dat",50); // load it
++ at end verbatim
++ at end itemize
++
++Creation of 2d- and 3d-arrays is mostly the same. But one should keep in mind that class @code{mglData} uses flat data representation. For example, matrix 30*40 is presented as flat (1d-) array with length 30*40=1200 (nx=30, ny=40). The element with indexes @{i,j@} is a[i+nx*j]. So for 2d array we have:
++ at verbatim
++ mglData z(30,40);
++ for(int i=0;i<30;i++) for(int j=0;j<40;j++)
++ z.a[i+30*j] = sin(M_PI*i/29.)*sin(M_PI*j/39.);
++ at end verbatim
++or by using @code{Modify()} function
++ at verbatim
++ mglData z(30,40);
++ z.Modify("sin(pi*x)*cos(pi*y)");
++ at end verbatim
++
++The only non-obvious thing here is using multidimensional arrays in C/C++, i.e. arrays defined like @code{float dat[40][30];}. Since, formaly this arrays element @code{dat[i]} can address the memory in arbitrary place you should use the proper function to convert such arrays to @code{mglData} object. For C++ this is functions like @code{mglData::Set(float **dat, int N1, int N2);}. For C this is functions like @code{mgl_data_set_float2(HMDT d, const float **dat, int N1, int N2);}. At this, you should keep in mind that @code{nx=N2} and @code{ny=N1} after conversion.

++ at subsection Data changing
++
++MathGL has functions for data processing: differentiating, integrating, smoothing and so on (for more detail, @pxref{mglData class}). Let us consider some examples. The simplest ones are integration and differentiation. The direction in which operation will be performed is specified by textual string, which may contain symbols @samp{x}, @samp{y} or @samp{z}. For example, the call of @code{Diff("x")} will differentiate data along @samp{x} direction; the call of @code{Integral("xy")} perform the double integration of data along @samp{x} and @samp{y} directions; the call of @code{Diff2("xyz")} will apply 3d Laplace operator to data and so on. Example of this operations on 2d array a=x*y is presented in code:
++ at verbatim
++ int sample(mglGraph *gr, void *)
++ {
++ mglData a(30,40); a.Modify("x*y");
++ gr->Axis(mglPoint(0,0,0),mglPoint(1,1,1));
++ gr->SubPlot(2,2,0); gr->Rotate(60,40);
++ gr->Surf(a); gr->Box();
++ gr->Puts(mglPoint(0.7,1,1.2),"a(x,y)");
++ gr->SubPlot(2,2,1); gr->Rotate(60,40);
++ a.Diff("x"); gr->Surf(a); gr->Box();
++ gr->Puts(mglPoint(0.7,1,1.2),"da/dx");
++ gr->SubPlot(2,2,2); gr->Rotate(60,40);
++ a.Integral("xy"); gr->Surf(a); gr->Box();
++ gr->Puts(mglPoint(0.7,1,1.2),"\\int da/dx dxdy");
++ gr->SubPlot(2,2,3); gr->Rotate(60,40);
++ a.Diff2("y"); gr->Surf(a); gr->Box();
++ gr->Puts(mglPoint(0.7,1,1.2),"\\int {d^2}a/dxdy dx");
++ return 0;
++ }
++ at end verbatim
++
++ at float
++ at image{png/sample6, 7cm}
++ at caption{Example of data differentiation and integration}
++ at end float
++
++Data smoothing (function @code{Smooth()}) is more interesting and important. This function has 2 main arguments: type of smoothing and its direction. Now 4 methods are supported: @code{SMOOTH_NONE} does nothing for delta=0 or approaches data to zero with the step delta, @code{SMOOTH_LINE_3} linear averaging by 3 points, @code{SMOOTH_LINE_5} linear averaging by 5 points, @code{SMOOTH_QUAD_5} quadratic averaging by 5 points. Let me demonstrate it for 1d case:
++ at verbatim
++ int sample(mglGraph *gr, void *)
++ {
++ mglData y0(30),y1,y2,y3;
++ y0.Modify("0.4*sin(2*pi*x)+0.3*cos(3*pi*x)-0.4*sin(4*pi*x)+0.2*rnd");
++
++ y1=y0; y1.Smooth(SMOOTH_LINE_3);
++ y2=y0; y2.Smooth(SMOOTH_LINE_5);
++ y3=y0; y3.Smooth(SMOOTH_QUAD_5);
++
++ gr->Plot(y0,"k"); gr->AddLegend("NONE","k");
++ gr->Plot(y1,"r"); gr->AddLegend("LINE_3","r");
++ gr->Plot(y2,"g"); gr->AddLegend("LINE_5","g");
++ gr->Plot(y3,"b"); gr->AddLegend("QUAD_5","b");
++ gr->Legend(); gr->Box();
++ return 0;
++ }
++ at end verbatim
++
++ at float
++ at image{png/sample7, 7cm}
++ at caption{Example of data smoothing}
++ at end float
++
++Finally one can create new data arrays on base of the existing one: extract slice, row or column of data (@code{SubData()}), summarize along some of direction(s) (@code{Sum()}), find distribution of data elements (@code{Hist()}). Note, that all these functions are not thread-safe because they use static internal variable for output array. In particular, the using of several of them in arguments of the same function will lead to unpredictable result.

++Let me now show how to plot the data. MathGL generally has 2 types of plotting functions. Simple variant requires a single data array for plotting, other data (coordinates) are considered uniformly distributed in interval @var{Min}*@var{Max}. Second variant requires data arrays for all coordinates. It allows one to plot rather complex multivalent curves and surfaces (in case of parametric dependencies). Argument setting to default values allows one to plot data in standard form. Manual arguments setting gives possibility for fine tuning of colors, positions and view of graphics. Note, that the call of drawing function adds something to picture but does not clear the previous plots (as it does in Matlab). Another difference from Matlab is that all setup (like transparency, lightning, axis borders and so on) must be specified @strong{before} plotting functions.

++ at subsection Plots for 1D data
++
++Term ``1D data'' means that data depend on single index (parameter) like curve in parametric form @{x(i),y(i),z(i)@}, i=1...n. There are 5 generally different types of data representations: simple line plot, line plot with filling under it, stairs plot, bar plot and vertical lines (@pxref{1D plotting}). Each type of plotting has similar interface. There are 3D version and two 2D versions. One of last requires single array. The parameters of line and marks (@pxref{Line styles}) are specified by the string argument. If the string parameter is @code{NULL} then solid line with color from palette is used (@pxref{Palette and colors}).
++
++Below I shall show the features of 1D plotting on base of @code{Plot()} function (@pxref{Plot}). Let us start from sinus plot:
++ at verbatim
++ int sample(mglGraph *gr, void *)
++ {
++ mglData y0(50); y0.Modify("sin(pi*(2*x-1))");
++ gr->SubPlot(2,2,0);
++ gr->Plot(y0); gr->Box();
++ at end verbatim
++Style of line is not specified in @code{Plot()} function. So MathGL uses the solid line with first color of palette (this is blue). Next subplot shows array @var{y1} with 2 rows:
++ at verbatim
++ gr->SubPlot(2,2,1);
++ mglData y1(50,2);
++ y1.Modify("sin(pi*2*x-pi)");
++ y1.Modify("cos(pi*2*x-pi)/2",1);
++ gr->Plot(y1); gr->Box();
++ at end verbatim
++As previously I did not specify the style of lines. As a result, MathGL again uses solid line with next colors in palette (there are green and red). Now let us plot a circle on the same subplot. The circle is parametric curve @math{x=cos(\pi t), y=sin(\pi t)}. I will set the color of the circle (dark yellow, @samp{Y}) and put marks @samp{+} at point position:
++ at verbatim
++ mglData x(50); x.Modify("cos(pi*2*x-pi)");
++ gr->Plot(x,y0,"Y+");
++ at end verbatim
++Note that solid line is used because I did not specify the type of line. The same picture can be achieved by @code{Plot2()} function. Let us draw ellipse by orange dash line:
++ at verbatim
++ gr->Plot2(y1,"q|");
++ at end verbatim
++
++Drawing in 3D space is mostly the same. Let us draw spiral with default line style. Now its color is 4-th color from palette (this is cyan):
++ at verbatim
++ gr->SubPlot(2,2,2); gr->Rotate(60,40);
++ mglData z(50); z.Modify("2*x-1");
++ gr->Plot(x,y0,z); gr->Box();
++ at end verbatim
++Function @code{Plot3()} does 3D curve plot but for single array. Use it to put circle marks on the previous plot:
++ at verbatim
++ mglData y2(10,3); y2.Modify("cos(pi*(2*x-1+y))");
++ y2.Modify("2*x-1",2);
++ gr->Plot3(y2,"bo ");
++ at end verbatim
++Note that line style is empty @samp{ } here. Usage of other 1D plotting functions looks similar:
++ at verbatim
++ gr->SubPlot(2,2,3); gr->Rotate(60,40);
++ gr->Bars(x,y0,z,"r"); gr->Box();
++ return 0;
++ }

++ at subsection Plots for 2D data
++
++Surfaces @code{Surf()} and other 2D plots (@pxref{2D plotting}) are drown the same simpler as 1D one. The difference is that the string parameter specifies not by line style but by the color scheme of the plot (@pxref{Color scheme}). Here I draw attention on 4 most interesting color schemes. There is gray scheme where color is changed from black to white (string @samp{kw}) or from white to black (string @samp{wk}). Another scheme is useful for accentuation of negative (by blue color) and positive (by red color) regions on plot (string @samp{"BbwrR"}). Last one is the popular ``jet'' scheme (string @samp{"BbcyrR"}).
++
++Now I shall show the example of a surface drawing. At first let us switch lightning on
++ at verbatim
++ int sample(mglGraph *gr, void *)
++ {
++ gr->Light(true); gr->Light(0,mglPoint(0,0,1));
++ at end verbatim
++and draw the surface, considering coordinates x,y to be uniformly distributed in interval @var{Min}*@var{Max}
++ at verbatim
++ mglData a0(50,40);
++ a0.Modify("0.6*sin(2*pi*x)*sin(3*pi*y)+0.4*cos(3*pi*(x*y))");
++ gr->SubPlot(2,2,0); gr->Rotate(60,40);
++ gr->Surf(a0); gr->Box();
++ at end verbatim
++Color scheme was not specified. So previous color scheme is used. In this case it is default color scheme (``jet'') for the first plot. Next example is a sphere. The sphere is parametrically specified surface:
++ at verbatim
++ mglData x(50,40),y(50,40),z(50,40);
++ x.Modify("0.8*sin(2*pi*x)*sin(pi*y)");
++ y.Modify("0.8*cos(2*pi*x)*sin(pi*y)");
++ z.Modify("0.8*cos(pi*y)");
++ gr->SubPlot(2,2,1); gr->Rotate(60,40);
++ gr->Surf(x,y,z,"BbwrR");gr->Box();
++ at end verbatim
++I set color scheme to @code{"BbwrR"} that corresponds to red top and blue bottom of the sphere.
++
++Surfaces will be plotted for each of slice of the data if @var{nz}>1. Next example draws surfaces for data arrays with @var{nz}=3:

++Drawing of other 2D plots is analogous. The only peculiarity is the usage of flag @samp{#}. By default this flag switches on the drawing of a grid on plot (@code{Grid()} or @code{Mesh()} for plots in plain or in volume). However, for isosurfaces (including surfaces of rotation @code{Axial()}) this flag switches the face drawing off. Figure becomes wired.

++Drawing procedures for 3D plot looks similarly to 1D and 2D plots described above. There are 3 general types of 3D plots (@pxref{3D plotting}): (i) plots on slices or on projections, (ii) isosurfaces, (iii) cloud-like plots. Plots on slice are clear enough -- one specifies a slice (as its index or as coordinate value) and MathGL draws contour lines or density plot on slice plane. Isosurface gives more information. Isosurface is 3D analogue of the contour line @code{Cont()}. It shows the region where data array values exceed specified isosurface level. Plot becomes more informative if one adds transparency, lightning or sets color scheme depending on coordinates. Generalization of isosurface is the cloud-like plot. For this plot the darker color and less transparent regions correspond to higher values of data. Contrary, the regions with low values are transparent. For plotting of the phase of fields (or beams or pulses) one can use isosurface which transparency depends on the other data array (see function @code{Surf3A()}). As example of 3D data plots let us draw the Gaussian beam diffraction in space. Beam propagates along @var{x} axis:
++ at verbatim
++ int sample(mglGraph *gr, void *)
++ {
++ gr->Alpha(true); gr->Light(true);
++ gr->Light(0,mglPoint(0,0,1));
++ mglData a(30,30,30),b(30,30,30);

++ at node Surface transparency, , Plots for 3D data, Data plotting
++ at subsection Surface transparency
++
++MathGL library has advanced features for setting and handling the surface transparency. The simplest way to add transparency is the using of function @code{Alpha()}. As a result, all further surfaces (and isosurfaces, density plots and so on) become transparent. However, their look can be additionally improved.
++
++First, the selected surface will be non-transparent if one sets the flag @code{Transparent} before the surface drawing and sets it off after the drawing.
++
++Second, the value of transparency can be different from surface to surface. To do it just change the value of @code{AlphaDef} before the drawing of the selected surface. If its value is close to 0 then the surface becomes more and more transparent. Contrary, if its value is close to 1 then the surface becomes practically non-transparent. This is some analogue of @code{Transparent=true}.
++
++Third feature is the changing of the way how the light goes through overlapped surfaces. The variable @code{TranspType} defines it. By default the usual transparency is used (@code{TranspType=0}) -- surfaces below is less visible than the upper ones. A ``glass-like'' transparency (@code{TranspType=1}) has a different look when the surface just decreases the background light (the surfaces are commutable in this case).
++
++A ``neon-like'' transparency (@code{TranspType=2}) has more interesting look. In this case a surface is the light source (like a lamp on the dark background) and just adds some intensity to the color. At this, the library sets automatically the black color for the background and changes the default line color to white.
++
++As example I shall show the variant of plot from @ref{Plots for 2D data} (grid drawing is disabled) for different types of transparency.

++ at section C/Fortran interface
++
++The usage of pure C or Fortran or any similar interfaces (@pxref{C interface}) is practically identical to classes usage. But there are some differences. C functions must have argument HMGL (for graphics) and/or HMDT (for data arrays) which specifies the object for drawing or manipulating (changing). Fortran users may regard these variables as integer. So, firstly the user has to create this object by function mgl_create_*() and has to delete it after the using by function mgl_delete_*().
++
++Also, all arguments of C function have to be defined. So there are several functions with practically identical names doing practically the same. But some of them have simplified interface for the quick plotting and some of them have access to all plotting parameters for manual tunning.
++
++As an example of C function usage let me draw the plot from @ref{Plots for 2D data}. The C code which does it is shown below:
++ at verbatim
++ #include <mgl/mgl_c.h>
++ int main()
++ {
++ HMGL gr = mgl_create_graph_zb(600, 400);
++ mgl_set_alpha(gr, true);
++ mgl_set_light(gr, true);
++ HMDT a = mgl_create_data_size(30,20,1);
++ mgl_data_modify(a,"0.6*sin(2*pi*x)*sin(3*pi*y) + 0.4*cos(3*pi*(x*y))",0);

++ mgl_box(gr, true);
++
++ /* don't forgot to save graphics */
++ mgl_write_png(gr,"sample.png",0);
++ return 0;
++ }
++ at end verbatim
++
++Practically the same simple to create a window. For example let rewrite the code from for window creation (@pxref{Using FLTK/GLUT window}):

++ at node ``Compound'' graphics, Two axes in one plot, , Hints
++ at subsection ``Compound'' graphics
++
++As I noted above, MathGL functions (except the special one, like Clf()) do not erase the previous plotting but just add the new one. It allows one to draw ``compound'' plots easily. For example, popular Matlab command @code{surfc} can be emulated in MathGL by 2 calls:
++ at verbatim
++ Surf(a);
++ Cont(a, 0, 7, -1); // draw contours at z = -1
++ at end verbatim
++Here @var{a} is 2-dimensional data for the plotting, @code{-1} is the value of z-coordinate at which the contour should be plotted (at the bottom in this example). Analogously, one can draw density plot instead of contour lines and so on.
++
++Another nice plot is contour lines plotted directly on the surface:
++ at verbatim
++ Light(true); // switch on light for the surface
++ Surf(a, "BbcyrR"); // select 'jet' colormap for the surface
++ Cont(a, "y"); // and yellow color for contours
++ at end verbatim
++The possible difficulties arise in black&white case, when the color of the surface can be close to the color of a contour line. In that case I may suggest the following code:
++ at verbatim
++ Light(true); // switch on light for the surface
++ Surf(a, "kw"); // select 'gray' colormap for the surface
++ CAxis(-1,0); // first draw for darker surface colors
++ Cont(a, "w"); // white contours
++ CAxis(0,1); // now draw for brighter surface colors
++ Cont(a, "k"); // black contours
++ CAxis(-1,1); // return color range to original state
++ at end verbatim
++The idea is to divide the color range on 2 parts (dark and bright) and to select the contrasting color for contour lines for each of part.
++
++Similarly, one can plot flow thread over density plot of vector field amplitude (this is another amusing plot from Matlab) and so on. The list of compound graphics can be prolonged but I hope that the general idea is clear.
++
++ at c ------------------------------------------------------------------
++ at node Two axes in one plot, Titles for the plot, ``Compound'' graphics, Hints
++ at subsection Two axes in one plot
++
++Developing the previous hint one can make a plot with 2 or more axes. The idea is that the change of settings does not influence on the already drawn graphics. So, for 2-axes plot let us set the first axis and draw everything concerning it. Then let us setup the second axis and draw things for the second axis. The corresponding code is (@pxref{2-axes sample}):
++ at verbatim
++ // set up first axis
++ Axis(mglPoint(-1,-1,-1),mglPoint(1,1,1),mglPoint(-1,-1,-1));
++ Axis(); // draw it
++ Plot(y1,"b"); // draw something in first axis
++ // set up second axis
++ Axis(mglPoint(0,0,0),mglPoint(1,1,1),mglPoint(1,1,1));
++ Axis(); // draw it
++ Stem(y2,"r"); // draw something in second axis
++ at end verbatim
++Note, that the first and the second axes look better if being placed in different corners. In the code presented above the first axis is placed in the left-bottom corner, and the second one is placed in the right-top corner.
++
++ at c ------------------------------------------------------------------
++ at node Titles for the plot, Changing of the color range, Two axes in one plot, Hints
++ at subsection Titles for the plot
++
++The printing of nice titles for the plot is not so trivial task in general case. The problem is that the rotation and aspect change lead to different looks for titles of different subplots. So, the resulting look is not so good as it could be. The solution is simple -- to print titles exactly after @code{SubPlot}() call and before any rotation, aspect change and so on! Analogously, the title for the whole picture looks better if it is printed first (before any @code{SubPlot()} calls). Alternatively you can use function @code{Title()} for plotting title for the picture at any time.
++
++ at c ------------------------------------------------------------------
++ at node Changing of the color range, Management of the point cutting, Titles for the plot, Hints
++ at subsection Changing of the color range
++
++By default (for the user comfort), the color range is set equal to z-range of the plot. However, there are different ranges. So, one can obtain amusing plot by the change of color range manually. For example, there are plots with one-color bottom (or top) or practically bi-color picture and so on.
++
++For example, compare 2 surfaces:
++ at verbatim
++ SubPlot(2,1,0)
++ Axis(mglPoint(-1,-1,-1),mglPoint(1,1,1),mglPoint(-1,-1,-1));
++ Surf(a); // usual coloring range
++ SubPlot(2,1,1)
++ CAxis(0,1);
++ Surf(a); // bottom of the surface have one-colour filling
++ at end verbatim
++
++ at c ------------------------------------------------------------------
++ at node Management of the point cutting, Vector field visualization, Changing of the color range, Hints
++ at subsection Management of the point cutting
++
++Sometimes an experimental or numerical surface has outstanding points. Visualization of such surface will lead to the hole(s) in place of such points. The standard method of ``fighting'' -- to change data values -- is not always good and is not so convenient. MathGL library has another method -- to set variable @code{Cut=false}. As a consequence, all outstanding points will be projected on the bounding box.
++
++Such method is good not only for outstanding points but also for the case when one need to plane the bottom or the top of the plot. Exactly such case is demonstrated in the code:
++ at verbatim
++ mglData a(20,30); // create some data
++ a.a.Modify("0.6*sin(2*pi*x)*sin(3*pi*y) + 0.4*cos(3*pi*(x*y))");
++ // set lower border above the data minimal value
++ Axis(mglPoint(-1,-1,0),mglPoint(1,1,1));
++ Cut = false; // set off cutting flag
++` Surf(a); // and draw the surface
++ at end verbatim
++It is an interesting result, is not it?

++
++Vector field visualization (especially in 3d case @code{Vect3} or @code{VectC}) may look tangly -- there are too many overlapping lines. I may suggest 2 ways to solve this problem. The first one is to change @code{MeshNum} for decreasing the number of hachures. The second way is to use the flow thread chart @code{Flow}. Unfortunately, I don't know any other methods to visualize 3d vector field. If you know any, e-mail me and I shall add it to MatGL.
++

++ at node Several light sources, CutMin and CutMax features, Vector field visualization, Hints
++ at subsection Several light sources
++
++In contrast to the most of other programs, MathGL supports several (up to 10) light sources. Moreover, the color each of them can be different: white (this is usual), yellow, red, cyan, green and so on. The use of several light sources may be interesting for the highlighting of some peculiarities of the plot or just to make an amusing picture. Note, each light source can be switched on/off individually (@pxref{Several light sample}).
++
++ at c ------------------------------------------------------------------
++ at node CutMin and CutMax features, Mapping visualization, Several light sources, Hints
++ at subsection CutMin and CutMax features
++
++MathGL library has a feature for cutting of points in some region @var{CutMin*CutMax}. Such an excision can be used to improve the look of the graphics. Moreover, this cutting may help to show an internal structure of an object (like @code{isocaps} plot in Matlab). For example, let us use the standard 3D data array and show its interior (@pxref{CutMinMax sample}).
++
++ at verbatim
++ mglData c(61,51,40); // create the data
++ mglData v(10); v.Fill(-0.5,1);
++ c.Modify("(-2*((2*x-1)^2 + (2*y-1)^2 + (2*z-1)^4 - (2*z-1)^2 - 0.1))");
++ gr->CutMin = mglPoint(0,-1,-1); gr->CutMax = mglPoint(1,0,1.1);

++ at end verbatim
++
++One can also exclude points from arbitrary area in space. This area defined by textual formula @code{CutOff()} (@pxref{Cutting}). The algorithm is the same as shown for ``rectangular cutting''.
++
++ at c ------------------------------------------------------------------
++ at node Mapping visualization, Log-scaled plot, CutMin and CutMax features, Hints
++ at subsection Mapping visualization
++
++Sometime ago I worked with mapping and have a question about its visualization. Let me remember you that mapping is some transformation rule for one set of number to another one. The 1d mapping is just an ordinary function -- it takes a number and transforms it to another one. The 2d mapping (which I used) is a pair of functions which take 2 numbers and transform them to another 2 ones. Except general plots (like @code{SurfC}, @code{SurfA}) there is a special plot -- Arnold diagram. It shows the area which is the result of mapping of some initial area (usually square).
++
++I tried to make such plot in @code{Map}. It shows the set of points or set of faces, which final position is the result of mapping. At this, the color gives information about their initial position and the height describes Jacobian value of the transformation. Unfortunately, it looks good only for the simplest mapping but for the real multivalent quasi-chaotic mapping it produces a confusion. So, use it if you like :).
++
++ at c ------------------------------------------------------------------
++ at node Log-scaled plot, ``Templates'', Mapping visualization, Hints
++ at subsection Log-scaled plot
++
++Log-scaled plot can be drawn by 2 steps. First, one should change the scale of axis by call @code{Axis("lg(x)", "lg(y)", 0);} (in this example, x- and y-axis will be log-scaled). Second, one should set logarithmic scale for axis ticks by changing variables: @code{SetTicks('x',0); SetTicks('y',0);}. Finally, one should check (or change) the axis ranges and origin so that their values to be positive. For example of log-log plot @pxref{Log-log sample}.
++
++ at c ------------------------------------------------------------------
++ at node ``Templates'', Nonlinear fitting hints, Log-scaled plot, Hints
++ at subsection ``Templates''
++
++As I have noted before, the change of settings will influence only for the further plotting commands. This allows one to create template function which will contain settings and primitive drawing for often used plots. Correspondingly one may call this template-function for drawing simplification.
++
++For example, let one has a set of points (experimental or numerical) and wants to compare it with theoretical law (for example, with exponent law @math{\exp(-x/2), x \in [0, 20]}). The template-function for this task is:
++ at verbatim
++ void template(mglGraph *gr)
++ {
++ mglData law(100); // create the law
++ law.Modify("exp(-10*x)");
++ gr->Axis(mglPoint(0,0.0001), mglPoint(20,1), mglPoint(0,0.0001));
++ gr->Axis(0,"lg(y)",0); gr->dy = 0;
++ gr->Plot(law,"r2");
++ gr->Text(mglPoint(10,0.2),"Theoretical law: e^x","rL");
++ gr->Label('x',"x val."); gr->Label('y',"y val.");
++ gr->Axis(); gr->Grid("xy","g;"); gr->Box();
++ }
++ at end verbatim
++At this, one will only write a few lines for data drawing:
++ at verbatim
++ template(gr); // apply settings and default drawing from template
++ mglData dat("fname.dat"); // load the data
++ // and draw it (suppose that data file have 2 columns)
++ gr->Plot(dat.SubData(0),dat.SubData(1),"bx ");
++ at end verbatim
++A template-function can also contain settings for font, transparency, lightning, color scheme and so on.
++
++ at c ------------------------------------------------------------------
++ at node Nonlinear fitting hints, , ``Templates'', Hints
++ at subsection Nonlinear fitting hints
++
++Nonlinear fitting is rather simple. All that you need is the data to fit, the approximation formula and the list of coefficients to fit (better with its initial guess values). Let me demonstrate it on the following simple example (@pxref{Fitting sample}). First, let us use sin function with some random noise:
++ at verbatim
++ mglData rnd(100), idl(50); //data to be fitted and ideal data
++ rnd.Modify("0.4*rnd+0.1+sin(4*pi*x)");
++ idl.Modify("0.3+sin(4*pi*x)");
++ at end verbatim
++and plot it to see that data we will fit
++ at verbatim
++ gr->Axis(mglPoint(-1,-2), mglPoint(1,2));
++ gr->Plot(rnd, ". "); gr->Plot(idl, "b");
++ gr->Box();
++ gr->Text(mglPoint(0,2.2), "initial: y = 0.3+sin(2\pi x)", "C:b", -1);
++ at end verbatim
++
++The next step is the fitting itself. For that let me specify an initial values @var{ini} for coefficients @samp{abc} and do the fitting for approximation formula @samp{a+b*sin(c*x)}
++ at verbatim
++ mglData res; // The data for found formula
++ float ini[3] = {1, 1, 3};
++ gr->Fit(res, rnd, "a+b*sin(c*x)", "abc", ini);
++ at end verbatim
++Now display it
++ at verbatim
++ gr->Plot(res, "r");
++ gr->Text(mglPoint(-1,-1.3), "fitted:", "L:r", -1);
++ gr->PutsFit(mglPoint(0,-1.8), "y = ", "C:r", -1);
++ at end verbatim
++
++NOTE! the fitting results may have strong dependence on initial values for coefficients due to algorithm features. The problem is that in general case there are several local "optimums" for coefficients and the program returns only first found one! There are no guaranties that it will be the best. Try for example to set @code{ini[3] = @{0, 0, 0@}} in the code above.

++
++Solving of Partial Differential Equations (PDE, including beam tracing) and ray tracing (or finding particle trajectory) are more or less common task. So, MathGL have several functions for that. There are @code{mglRay()} for ray tracing, @code{mglPDE()} for PDE solving, @code{mglQO2d()} for beam tracing in 2D case (@pxref{Global functions}). Note, that these functions take ``Hamiltonian'' or equations as string values. And I don't plan now to allow one to use user-defined functions. There are 2 reasons: the complexity of corresponding interface; and the basic nature of used methods which are good for samples but may not good for serious scientific calculations.
++
++The ray tracing can be done by @code{mglRay()} function. Really ray tracing equation is Hamiltonian equation for 3D space. So, the function can be also used for finding a particle trajectory (i.e. solve Hamiltonian ODE) for 1D, 2D or 3D cases. The function have a set of arguments. First of all, it is Hamiltonian which defined the media (or the equation) you are planning to use. The Hamiltonian is defined by string which may depend on coordinates @samp{x}, @samp{y}, @samp{z}, time @samp{t} (for particle dynamics) and momentums @samp{p}=@math{p_x}, @samp{q}=@math{p_y}, @samp{v}=@math{p_z}. Next, you have to define the initial conditions for coordinates and momentums at @samp{t}=0 and set the integrations step (default is 0.1) and its duration (default is 10). The Runge-Kutta method of 4-th order is used for integration.
++ at verbatim
++ mglData r,a,re(128),im(128);
++ r = mglRay("p^2+q^2-x-1", mglPoint(-0.7, -1), mglPoint(0, 0.5));
++ gr->Plot(r.SubData(0), r.SubData(1));
++ at end verbatim
++This example calculate the reflection from linear layer (media with Hamiltonian @samp{p^2+q^2-x-1}=@math{p_x^2+p_y^2-x-1}). This is parabolic curve. The resulting array have 7 columns which contain data for @{x,y,z,p,q,v,t@}.
++
++The solution of PDE is a bit more complicated. As previous you have to specify the equation as pseudo-differential operator @math{\hat H(x, \nabla)} which is called sometime as ``Hamiltonian'' (for example, in beam tracing). As previously, it is defined by string which may depend on coordinates @samp{x}, @samp{y}, @samp{z} (but not time!), momentums @samp{p}=@math{(d/dx)/i k_0}, @samp{q}=@math{(d/dy)/i k_0} and field amplitude @samp{u}=@math{|u|}. The evolutionary coordinate is @samp{z} in all cases. So that, the equation look like @math{du/dz = ik_0 H(x,y,\hat p, \hat q, |u|)[u]}. Dependence on field amplitude @samp{u}=@math{|u|} allows one to solve nonlinear problems too. For example, for nonlinear Shrodinger equation you may set @code{ham="p^2 + q^2 - u^2"}. Also you may specify imaginary part for wave absorption, like @code{ham = "p^2 + i*x*(x>0)"}, but only if dependence on variable @samp{i} is linear (i.e. @math{H = Hre+i*Him}).
++
++Next step is specifing the initial conditions at @samp{z}=@code{Min.z}. The function need 2 arrays for real and for imaginary part. Note, that coordinates x,y,z are supposed to be in specified range [Min, Max]. So, the data arrays should have corresponding scales. Finally, you may set the integration step and paramter k0=@math{k_0}. Also keep in mind, that internally the 2 times large box is used (for suppressing numerical reflection from boundaries) and the equation should well defined even in this extended range.
++
++Final comment is concerning the possible form of pseudo-differential operator @math{H}. At this moment, simplified form of operator @math{H} is supported -- all ``mixed'' terms (like @samp{x*p}->x*d/dx) are excluded. For example, in 2D case this operator is effectively @math{H = f(p,z) + g(x,z,u)}. However commutable combinations (like @samp{x*q}->x*d/dy) are allowed for 3D case.
++
++So, for example let solve the equation for beam deflected from linear layer and absorbed later. The operator will have the form @samp{"p^2+q^2-x-1+i*0.5*(z+x)*(z>-x)"} that correspond to equation @math{ik_0 \partial_z u + \Delta u + x \cdot u + i (x+z)/2 \cdot u = 0}. This is typical equation for Electron Cyclotron (EC) absorption in magnetized plasmas. For initial conditions let me select the beam with plane phase front @math{exp(-48*(x+0.7)^2)}. The corresponding code looks like this (@pxref{PDE sample}):
++ at verbatim
++ mglData a,re(128),im(128);
++ re.Fill("exp(-48*(x+0.7)^2)", gr->Min, gr->Max);
++ a = mglPDE("p^2+q^2-x-1+i*0.5*(z+x)*(z>-x)", re, im,
++ gr->Min, gr->Max, 0.01, 30);
++ a.Transpose("yxz");
++ gr->CAxis(0, 1);
++ gr->Dens(a,"wyrRk");
++ at end verbatim
++
++The last example is example of beam tracing. Beam tracing equation is special kind of PDE equation written in coordinates accompanied to a ray. Generally this is the same parameters and limitation as for PDE solving but the coordinates are defined by the ray and by parameter of grid width @var{w} in direction transverse the ray. So, you don't need to specify the range of coordinates. @strong{BUT} there is limitation. The accompanied coordinates are well defined only for smooth enough rays, i.e. then the ray curvature @math{K} (which is defined as @math{1/K^2 = (|\ddot r|^2 |\dot r|^2 - (\ddot r, \dot r)^2)/|\dot r|^6}) is much large then the grid width: @math{K>>w}. So, you may receive incorrect results if this condition will be broken.
++
++You may use following code for obtaining the same solution as in previous example:
++ at verbatim
++ mglData r, xx, yy, a, im(128), re(128);
++ const char *ham = "p^2+q^2-x-1+i*0.5*(y+x)*(y>-x)";
++ r = mglRay(ham, mglPoint(-0.7, -1), mglPoint(0, 0.5), 0.02, 2);
++ // now start beam tracing
++ re.Fill("exp(-48*x^2)", gr->Min, gr->Max);
++ a = mglQO2d(ham, re, im, r, 1, 30, &xx, &yy);
++ gr->CAxis(0, 1);
++ gr->Dens(xx, yy, a, "wyrRk");
++ at end verbatim
++

++ at subsection MGL parser using
++
++Sometimes you may prefer to use MGL scripts in yours code. It is simpler (especcially in comparison with C/Fortran interfaces) and fast way to plot the data with annotations, labels and so on. Class @code{mglParse} (@pxref{mglParse class} parse MGL scripts in C++. It have also the corresponding interface for C/Fortran (@pxref{MGL parsing (Pure C)}).
++
++The key function here is @code{mglParse::Parse()} (or @code{mgl_parse()} for C/Fortran) which execute one command per string. At this the detailed information about the possible errors or warnings is passed as function value. Or you may execute the whole script as long string with lines separated by @samp{\n}. Functions @code{mglParse::Execute()} and @code{mgl_parse_text()} perform it. Also you may set the values of paramters @samp{$0}... at samp{$9} for the script by functions @code{mglParse::AddParam()} or @code{mgl_add_param()}, allow/disable picture resizing, check ``once'' status and so on. The usage is rather stright-forward.
++
++The only non-obvious thing is data transition between script and yours program. There are 2 stages: add or find variable; and set data to variable. In C++ you may use functions @code{mglParse::AddVar()} and @code{mglParse::FindVar()} which return pointer to @code{mglVar} structure. This structure contain data itself, the variable name and callback function which will be called if variable destroied. Last feature allows you to control the presence of the variable and, for example, close a window with data if this variable is destroyed. In C/Fortran the corresponding functions are @code{mgl_add_var()}, @code{mgl_find_var()}. But these functions return the data array only. Note, you @strong{must not delete or free} the data obtained from these functions!
++
++So, some simple example at the end. Here I define a data array, create variable, put data into it and plot it. The C++ code looks like this:
++ at verbatim
++ float a[100]; // let a_i = sin(4*pi*x), x=0...1
++ for(int i=0;i<100;i++) a[i]=sin(4*M_PI*i/99);
++ mglParse *parser = new mglParse;
++ mglData &d = (parser->AddVar("dat"))->d;
++ d.Set(a,100); // set data to variable
++ parser->Execute(gr, "plot dat; xrange 0 1\nbox\naxis");
++ // you may break script at any line do something
++ // and continue after that
++ parser->Execute(gr, "xlabel 'x'\nylabel 'y'");
++ // also you may use cycles or conditions in script
++ parser->Execute(gr, "for $0 -1 1 0.1\nline 0 0 -1 $0 'r'\nnext");
++ gr->WritePNG("test.png"); // don't forgot to save picture
++ at end verbatim
++The code in C/Fortran looks practically the same:
++ at verbatim
++ float a[100]; // let a_i = sin(4*pi*x), x=0...1
++ int i;
++ for(i=0;i<100;i++) a[i]=sin(4*M_PI*i/99);
++ HMPR parser = mgl_create_parser();
++ HMDT d = mgl_add_var(parser, "dat");
++ mgl_data_set_float(d,a,100,1,1); // set data to variable
++ mgl_parse_text(gr, parser, "plot dat; xrange 0 1\nbox\naxis");
++ // you may break script at any line do something
++ // and continue after that
++ mgl_parse_text(gr, parser, "xlabel 'x'\nylabel 'y'");
++ // also you may use cycles or conditions in script
++ mgl_parse_text(gr, parser, "for $0 -1 1 0.1\nline 0 0 -1 $0 'r'\nnext");
++ mgl_write_png(gr, "test.png", ""); // don't forgot to save picture

++
++MathGL library have interface for a set of languages. Most of them are based on C interface via SWIG tool. There are Python, Java, Octave, Lisp, C#, Guile, Lua, Modula 3, Ocaml, Perl, PHP, Pike, R, Ruby, Tcl. Also there is Fortran interface which have similar set of functions but slightly different type of arguments (integers instead of pointers). The C interface functions are described in @ref{C interface}.
++ at c ++++++++++
++Some of languages listed above support classes (like Python). So for them the special wrapper was written. These classes and functions are described in @ref{Python interface}.
++ at c ++++++++++
++Finally the special command language MGL was written for faster access to C++ plotting functions. Corresponding scripts can be executed separately (by UDAV, mgl2png, mgl2eps and so on) or from the C++ code (@pxref{mglParse class}). These commands are described in @ref{MGL interface}.
++
++C interface is base for many other interfaces. It contain pure C functions for most of methods of MathGL classes. In difference from C++ classes, C functions must have argument HMGL (for graphics) and/or HMDT (for data arrays) which specify the object for drawing or manipulating (changing). So, firstly user have to create this object by function @code{mgl_create_*()} and have to delete it after using by function @code{mgl_delete_*()}.
++
++All C functions are described in header file @code{#include <mgl/mgl_c.h>}
++and use variable of types:
++ at itemize
++ at item
++ at code{HMGL} --- Pointer to class @code{mglGraph} (@pxref{MathGL core}).
++ at item
++ at code{HMDT} --- Pointer to class @code{mglData} (@pxref{mglData class}).
++ at item
++ at code{HMPR} --- Pointer to class @code{mglParse} (@pxref{mglParse class})..
++ at end itemize
++These variables contain identifiers for graphics drawing objects and for data objects.
++
++Fortran functions/subroutines have the same names as C functions. However, there is a difference. Variable of types @code{HMGL, HMDT} must be integer with sufficient size (@code{integer*4} for 32-bit operating system or @code{integer*8} for 64-bit operating system). All C functions are subroutines in Fortran which should be called by operator @code{call}. The exceptions are functions which return variables of types @code{HMGL} or @code{HMDT}. These functions should be declared as integer in Fortran code. Also one should keep in mind that strings in Fortran are denoted by @code{'} sign but not @code{"} one.
++
++For compiling Fortran program you should specify AT&T calling conversion (it is default for gfortran, g77 and so on). The internal difference of AT&T interface from C interface is that the symbol '_' is added at the end of function name, and string length(s) is passed at the end of argument list. For example:
++ at itemize
++ at item
++C function is
++
++void mgl_fplot(HMGL graph, const char *fy, const char *stl, int n);
++
++ at item
++AT&T function is
++
++void mgl_fplot_(uintptr_t *graph, const char *fy, const char *stl, int
++*n, int ly, int ls);

++There are several functions for setup lighting. The general function is @code{mgl_set_light()} which switch on/off the lighting for overall plot. It influence only for graphics which created after @code{mgl_set_light()} call. Generally MathGL support up to 10 independent light sources. But in OpenGL mode only 8 of light sources is used due to OpenGL limitations. The position, color, brightness of each light source can be set separately. By default only one light source is active. It is source number @code{0} with white color, located at top of the plot.

++These functions control how and where further plotting will be placed. There is a curtain order of calling of these functions for the better plot view. First one should be SubPlot() or InPlot() for specifying the place. After it a Rotate() and Aspect(). And finally any other plotting functions may be called. Alternatevely you can use ColumnPlot() for position plots in the column one by another without gap between plot axis (bounding boxes).

++These functions draw the text. There are functions for drawing text in arbitrary place, in arbitrary direction and along arbitrary curve. The class mglFont (@pxref{mglFont class}) is used for low-level string parsing and printing. It can use arbitrary font-faces and parse many TeX commands. All these functions have 2 variant: for printing 8-bit text (@code{char *}) and for printing Unicode text (@code{wchar_t *}). In first case the conversion in current locale is used. So sometimes you need to specify it by @code{setlocale()} function. The size argument control the size of text: if positive it give the value, if negative it give the value relative to @var{FontSize}. The font type (STIX, arial, courier, times and so on) can be selected by function @code{mgl_load_font()}. @xref{Font settings (Pure C)}.
++
++The font parameters are described by string. This string may contain several characters of font type (@samp{rbiwou}) and/or align (@samp{LRC}) specification. Also it may contain the text color @samp{wkrgbcymhRGBCYMHW} (@pxref{mglColor class}) after symbol @samp{:}. The font types are: @samp{r} -- roman font, @samp{i} -- italic style, @samp{b} -- bold style, @samp{w} -- wired style, @samp{o} -- over-lined text, @samp{u} -- underlined text. By default roman font is used. The align types are: @samp{L} -- align left (default), @samp{C} -- align center, @samp{R} -- align right. Also a parsing of the LaTeX-like syntax is provided (for detail @pxref{mglFont class}). For example, string @samp{iC:b} correspond to italic font style for centered text which printed by blue color.

++These functions perform plotting of 1D data. 1D means that data depended from only 1 parameter like parametric curve @{x(i),y(i),z(i)@}, i=1...n. There are 5 generally different types of data representations: simple line plot (Plot), line plot with filling under it (Area), stairs plot (Step), bar plot (Bars, Barh) and vertical lines (Stem). Each type of plotting has similar interface. There are 3D version and two 2D versions. One of last requires single array. The parameters of line and marks are specified by the string argument. If the string parameter is NULL then solid line with color from palette Pal is used (@pxref{Palette and colors}). Also there are some special 1d plots having slightly different interface: surface of curve rotation (Torus), chart (Chart) and error boxes (Error), marks with variable size (Mark), tubes (Tube) and so on. @xref{Line styles}.

++These functions perform plotting of 2D data. 2D means that data depend from 2 independent parameters like matrix @math{f(x_i,y_j), i=1...n, j=1...m}. There are 6 generally different types of data representations: simple mesh lines plot (Mesh), surface plot (Surf), surface plot by boxes (Boxs), surface plot by tiles (Tile), waterfall-like plot (Fall), belt plot (Belt), density plot (Dens), contour lines plot (Cont), solid contours plot (ContF) and its rotational figure (Axial). Cont, ContF and Axial functions have variants for automatic and manual selection of level values for contours. Also there are functions for plotting data grid lines according to the data format (Grid) for enhancing density or contour plots. Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These functions perform plotting of 3D data. 3D means that data depend from 3 independent parameters like matrix @math{f(x_i,y_j,z_k), i=1...n, j=1...m, k=1...l}. There are 4 generally different types of data representations: isosurface or surface of constant value (Surf3), density plot at slices (Dens3), contour lines plot at slices (Cont3), solid contours plot at slices (ContF3) and cloud-like plot (Cloud). Surf3, Cont3 and ContF3 functions have variants for automatic and manual selection of level values for surfaces/contours. Also there are functions for plotting data grid lines according to the data format (Grid3) for enhancing density or contour plots. Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These functions perform plotting of 2D and 3D vector fields. There are 5 generally different types of vector fields representations: simple vector field (Vect), vector field with coloring (VectC), vector field by dew-drops (Dew), flow threads (Flow), flow pipes (Pipe). Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These functions fit data to formula. Fitting goal is to find formula parameters for the best fit the data points, i.e. to minimize the sum @math{\sum_i (f(x_i, y_i, z_i) - a_i)^2/s_i^2}. At this, approximation function @samp{f} can depend only on one argument @samp{x} (1D case), on two arguments @samp{x,y} (2D case) and on three arguments @samp{x,y,z} (3D case). The function @samp{f} also may depend on parameters. Normally the list of fitted parameters is specified by @var{var} string (like, @samp{abcd}). Usually user should supply initial values for fitted parameters by @var{ini} variable. But if he/she don't supply it then the zeros are used.
++
++Functions Fit() and FitS() do not draw the obtained data themselves. They fill the data @var{fit} by formula @samp{f} with found coefficients and return the @math{\chi^2} error of approximation. At this, the @samp{x,y,z} coordinates are equidistantly distributed in the interval @var{Min}-- at var{Max}. Number of points in @var{fit} is selected as maximal value of @var{fit} size and the value of @var{FitPnts}.

++
++MathGL provide the interface to a set of languages via SWIG library. Some of these languages support classes. The typical example is Python -- which is denoted in the chapter title.
++
++To use Python classes just execute @samp{import mathgl}. The simplest example will be:
++ at verbatim
++import mathgl
++a=mathgl.mglGraph()
++a.Box()
++a.WritePNG('test.png')
++ at end verbatim
++Alternatively you can import all classes from @code{mathgl} module and easily access MathGL classes:
++ at verbatim
++from mathgl import *
++a=mglGraph()
++a.Box()
++a.WritePNG('test.png')
++ at end verbatim
++It become useful if you will create many @code{mglData} object, for example.
++
++There are 2 classes in Python interface:
++ at itemize
++ at item @code{mglGraph}
++-- provide practically the same functionality as C++ class @code{mglGraph} (@pxref{MathGL core}). But it is not abstract class and it allows one to select at construction stage which plotter (ZB or PS and so on) will be used.
++ at item @code{mglData}
++-- is absolutely the same class as C++ @code{mglData} (@pxref{mglData class}). But an additional feature to acess data values is added. You can use construction like this: @code{dat[i]=sth;} or @code{sth=dat[i]} at this flat representation of data is used (i.e., @var{i} can be in range 0...nx*nx*nz-1.
++ at c @item @code{mglParse} -- practically the same as C++ class @code{mglParse} (@pxref{mglParse class}).
++ at end itemize
++
++There is main difference from C++ classes -- Python class @code{mglGraph} don't have variables (options). All corresponding features are moved to methods.
++The core of MathGL Python class is @strong{mglGraph} class. It contains a lot of plotting functions for 1D, 2D and 3D plots. So most of sections is describe its methods. Its constructor have following arguments:
++
++ at defop Constructor {mglGraph (Python)} @code{} mglGraph (@code{int} kind=@code{0}, @code{int} width=@code{600}, @code{int} height=@code{400})
++Create the instance of class mglGraph with specified sizes @var{width} and @var{height}. Parameter @var{type} may have following values: @samp{0} -- use @code{mglGraphZB} plotter (default), @samp{1} -- use @code{mglGraphPS} plotter, @samp{2} -- use @code{mglGraphGL} plotter, @samp{3} -- use @code{mglGraphIDTF} plotter.

++There are several functions and variables for setup transparency. The general function is @code{Alpha()} which switch on/off the transparency for overall plot. It influence only for graphics which created after @code{Alpha()} call. Variable @code{SetAlphaDef()} specify the default value of alpha-channel. You may switch off transparency of selected plot by variable @code{SetTransparent()}. Finally, variable @code{SetTranspType()} set the kind of transparency. @sref{Transparent surface sample}
++
++ at deftypemethod {mglGraph (Python)} @code{void} Alpha (@code{bool} enable)
++Sets the transparency on/off. It is recommended to call this function before any plotting command. In any case it must be called before @code{Finish()} function if the last is used. Default value is transparency off. Unfortunately it switches the transparency on/off for all subplots. Use @code{SetTransparent(false)} in particular plot to disable its transparency.

++This variable set the transparency type. Normal transparency (@samp{0}) -- below things is less visible than upper ones. It does not look well in OpenGL mode (mglGraphGL) for several surfaces. Glass-like transparency (@samp{1}) -- below and upper things are commutable and just decrease intensity of light by RGB channel. Lamp-like transparency (@samp{2}) -- below and upper things are commutable and are the source of some additional light. I recommend to set @code{SetAlphaDef(0.3)} or less for lamp-like transparency.

But in OpenGL mode only 8 of light sources is used due to OpenGL limitations. The position, color, brightness of each light source can be set separately. By default only one light source is active. It is source number @code{0} with white color, located at top of the plot.

++These functions control how and where further plotting will be placed. There is a curtain order of calling of these functions for the better plot view. First one should be SubPlot() or InPlot() for specifying the place. After it a Rotate() and Aspect(). And finally any other plotting functions may be called. Alternatevely you can use ColumnPlot() for position plots in the column one by another without gap between plot axis (bounding boxes).

++These functions draw the text. There are functions for drawing text in arbitrary place, in arbitrary direction and along arbitrary curve. The class mglFont (@pxref{mglFont class}) is used for low-level string parsing and printing. It can use arbitrary font-faces and parse many TeX commands. All these functions have 2 variant: for printing 8-bit text (@code{char *}) and for printing Unicode text (@code{wchar_t *}). In first case the conversion in current locale is used. So sometimes you need to specify it by @code{setlocale()} function. The size argument control the size of text: if positive it give the value, if negative it give the value relative to @var{FontSize}. The font type (STIX, arial, courier, times and so on) can be selected by function LoadFont(). @xref{Font settings (Python)}.
++
++The font parameters are described by string. This string may contain several characters of font type (@samp{rbiwou}) and/or align (@samp{LRC}) specification. Also it may contain the text color @samp{wkrgbcymhRGBCYMHW} (@pxref{mglColor class}) after symbol @samp{:}. The font types are: @samp{r} -- roman font, @samp{i} -- italic style, @samp{b} -- bold style, @samp{w} -- wired style, @samp{o} -- over-lined text, @samp{u} -- underlined text. By default roman font is used. The align types are: @samp{L} -- align left (default), @samp{C} -- align center, @samp{R} -- align right. Also a parsing of the LaTeX-like syntax is provided (for detail @pxref{mglFont class}). For example, string @samp{iC:b} correspond to italic font style for centered text which printed by blue color.

++These functions perform plotting of 1D data. 1D means that data depended from only 1 parameter like parametric curve @{x(i),y(i),z(i)@}, i=1...n. There are 5 generally different types of data representations: simple line plot (Plot), line plot with filling under it (Area), stairs plot (Step), bar plot (Bars, Barh) and vertical lines (Stem). Each type of plotting has similar interface. There are 3D version and two 2D versions. One of last requires single array. The parameters of line and marks are specified by the string argument. If the string parameter is NULL then solid line with color from palette Pal is used (@pxref{Palette and colors (Python)}). Also there are some special 1d plots having slightly different interface: surface of curve rotation (Torus), chart (Chart) and error boxes (Error), marks with variable size (Mark), tubes (Tube) and so on. @xref{Line styles}.

++These functions perform plotting of 2D data. 2D means that data depend from 2 independent parameters like matrix @math{f(x_i,y_j), i=1...n, j=1...m}. There are 6 generally different types of data representations: simple mesh lines plot (Mesh), surface plot (Surf), surface plot by boxes (Boxs), surface plot by tiles (Tile), waterfall-like plot (Fall), belt plot (Belt), density plot (Dens), contour lines plot (Cont), solid contours plot (ContF) and its rotational figure (Axial). Cont, ContF and Axial functions have variants for automatic and manual selection of level values for contours. Also there are functions for plotting data grid lines according to the data format (Grid) for enhancing density or contour plots. Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These functions perform plotting of 3D data. 3D means that data depend from 3 independent parameters like matrix @math{f(x_i,y_j,z_k), i=1...n, j=1...m, k=1...l}. There are 4 generally different types of data representations: isosurface or surface of constant value (Surf3), density plot at slices (Dens3), contour lines plot at slices (Cont3), solid contours plot at slices (ContF3) and cloud-like plot (Cloud). Surf3, Cont3 and ContF3 functions have variants for automatic and manual selection of level values for surfaces/contours. Also there are functions for plotting data grid lines according to the data format (Grid3) for enhancing density or contour plots. Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These functions perform plotting of 2D and 3D vector fields. There are 5 generally different types of vector fields representations: simple vector field (Vect), vector field with coloring (VectC), vector field by dew-drops (Dew), flow threads (Flow), flow pipes (Pipe). Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These functions perform miscelaneous plotting. There is unstructured data points plots (Dots), surface reconstruction (Crust), surfaces on the triangular mesh (TriPlot), textual formula plotting (Plots by formula), data plots at edges (Dens[XYZ], Cont[XYZ], ContF[XYZ]), simple plot (SimplePlot). Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These functions fit data to formula. Fitting goal is to find formula parameters for the best fit the data points, i.e. to minimize the sum @math{\sum_i (f(x_i, y_i, z_i) - a_i)^2/s_i^2}. At this, approximation function @samp{f} can depend only on one argument @samp{x} (1D case), on two arguments @samp{x,y} (2D case) and on three arguments @samp{x,y,z} (3D case). The function @samp{f} also may depend on parameters. Normally the list of fitted parameters is specified by @var{var} string (like, @samp{abcd}). Usually user should supply initial values for fitted parameters by @var{ini} variable. But if he/she don't supply it then the zeros are used. Parameter @var{print}=@code{true} switch on printing the found coefficients to @var{Message} (@pxref{Error handling}).
++
++Functions Fit() and FitS() do not draw the obtained data themselves. They fill the data @var{fit} by formula @samp{f} with found coefficients and return the @math{\chi^2} error of approximation. At this, the @samp{x,y,z} coordinates are equidistantly distributed in the interval @var{Min}-- at var{Max}. Number of points in @var{fit} is selected as maximal value of @var{fit} size and the value of @var{FitPnts}.

++The core of MathGL is @strong{mglGraph} class defined in @code{#include <mgl/mgl.h>}. It contains a lot of plotting functions for 1D, 2D and 3D plots. It also encapsulates parameters for axes drawing. Moreover an arbitrary coordinate transformation may be used for each axis. All plotting functions use data encapsulated in mglData class (@pxref{mglData class}) that allows to check sizes of used arrays easily. Also it have many functions for data handling: modify it by formulas, find momentums and distribution (histogram), apply operator (differentiate, integrate, transpose, Fourier and so on), change data sizes (interpolate, squeeze, crop and so on). Additional information about colors, fonts, formula parsing can be found in @ref{Other classes}.
++
++Note that class mglGraph is abstract and contains only interface functions for plotting but does not make plot by itself. For plotting in specific device (screen, memory or file) one should use derived classes: mglGraphZB -- for bitmap picture in file or in memory; mglGraphPS -- for vector PostScript picture; mglGraphGL -- for drawing using OpenGL, or for GLUT windows interface; and so on, @pxref{Plotter classes}. If you want not only to create a picture but to view it in a window/widget or to run animation and so on then look at @ref{Widget classes}.

++There are several functions and variables for setup transparency. The general function is @code{Alpha()} which switch on/off the transparency for overall plot. It influence only for graphics which created after @code{Alpha()} call (with one exception, mglGraphGL). Variable @code{AlphaDef} specify the default value of alpha-channel. You may switch off transparency of selected plot by variable @code{Transparent}. Finally, variable @code{TranspType} set the kind of transparency. @sref{Transparent surface sample}
++
++ at deftypemethod mglGraph @code{bool} Alpha (@code{bool} enable)
++Sets the transparency on/off. It is recommended to call this function before any plotting command. Function returns previous value of transparency. In any case it must be called before @code{Finish()} function if the last is used. Default value is transparency off. Unfortunately it switches the transparency on/off for all subplots. Use @code{Transparent = false} in particular plot to disable its transparency.
++ at end deftypemethod

++This variable set the transparency type. Normal transparency (@samp{0}) -- below things is less visible than upper ones. It does not look well in OpenGL mode (mglGraphGL) for several surfaces. Glass-like transparency (@samp{1}) -- below and upper things are commutable and just decrease intensity of light by RGB channel. Lamp-like transparency (@samp{2}) -- below and upper things are commutable and are the source of some additional light. I recommend to set @code{AlphaDef = 0.3} or less for lamp-like transparency.

It influence only for graphics which created after @code{Light()} call (with one exception, mglGraphGL). Generally MathGL support up to 10 independent light sources. But in OpenGL mode only 8 of light sources is used due to OpenGL limitations. The position, color, brightness of each light source can be set separately. By default only one light source is active. It is source number @code{0} with white color, located at top of the plot.

++These functions draw the text. There are functions for drawing text in arbitrary place, in arbitrary direction and along arbitrary curve. The class mglFont (@pxref{mglFont class}) is used for low-level string parsing and printing. It can use arbitrary font-faces and parse many TeX commands. All these functions have 2 variant: for printing 8-bit text (@code{char *}) and for printing Unicode text (@code{wchar_t *}). In first case the conversion in current locale is used. So sometimes you need to specify it by @code{setlocale()} function. The size argument control the size of text: if positive it give the value, if negative it give the value relative to @var{FontSize}. The font type (STIX, arial, courier, times and so on) can be selected by function SetFont(), GetFont(). @xref{Font settings}.
++
++The font parameters are described by string. This string may contain several characters of font type (@samp{rbiwou}) and/or align (@samp{LRC}) specification. Also it may contain the text color @samp{wkrgbcymhRGBCYMHW} (@pxref{mglColor class}) after symbol @samp{:}. The font types are: @samp{r} -- roman font, @samp{i} -- italic style, @samp{b} -- bold style, @samp{w} -- wired style, @samp{o} -- over-lined text, @samp{u} -- underlined text. By default roman font is used. The align types are: @samp{L} -- align left (default), @samp{C} -- align center, @samp{R} -- align right.

++These functions perform plotting of 1D data. 1D means that data depended from only 1 parameter like parametric curve @{x(i),y(i),z(i)@}, i=1...n. There are 5 generally different types of data representations: simple line plot (Plot), line plot with filling under it (Area), stairs plot (Step), bar plot (Bars, Barh) and vertical lines (Stem). Each type of plotting has similar interface. There are 3D version and two 2D versions. One of last requires single array. The parameters of line and marks are specified by the string argument. If the string parameter is NULL then solid line with color from palette Pal is used (@pxref{Palette and colors}). Also there are some special 1d plots having slightly different interface: surface of curve rotation (Torus), chart (Chart) and error boxes (Error), marks with variable size (Mark), tubes (Tube) and so on. @xref{Line styles}.

++These functions perform plotting of 2D data. 2D means that data depend from 2 independent parameters like matrix @math{f(x_i,y_j), i=1...n, j=1...m}. There are 6 generally different types of data representations: simple mesh lines plot (Mesh), surface plot (Surf), surface plot by boxes (Boxs), surface plot by tiles (Tile), waterfall-like plot (Fall), belt plot (Belt), density plot (Dens), contour lines plot (Cont), solid contours plot (ContF) and its rotational figure (Axial). Cont, ContF and Axial functions have variants for automatic and manual selection of level values for contours. Also there are functions for plotting data grid lines according to the data format (Grid) for enhancing density or contour plots. Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These functions perform plotting of 3D data. 3D means that data depend from 3 independent parameters like matrix @math{f(x_i,y_j,z_k), i=1...n, j=1...m, k=1...l}. There are 4 generally different types of data representations: isosurface or surface of constant value (Surf3), density plot at slices (Dens3), contour lines plot at slices (Cont3), solid contours plot at slices (ContF3) and cloud-like plot (Cloud). Surf3, Cont3 and ContF3 functions have variants for automatic and manual selection of level values for surfaces/contours. Also there are functions for plotting data grid lines according to the data format (Grid3) for enhancing density or contour plots. Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These plotting functions draw @emph{two matrix} simultaneously. There are 5 generally different types of data representations: surface or isosurface colored by other data (SurfC, Surf3C), surface or isosurface transpared by other data (SurfA, Surf3A), tiles with variable size (TileS), mapping diagram (Map), STFA diagram (STFA). Surf3A and Surf3C have variants for automatic and manual selection of level values for isosurfaces. Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These functions perform plotting of 2D and 3D vector fields. There are 5 generally different types of vector fields representations: simple vector field (Vect, VectL), vector field with coloring (VectC), vector field by dew-drops (Dew), flow threads (Flow), flow pipes (Pipe). Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These functions fit data to formula. Fitting goal is to find formula parameters for the best fit the data points, i.e. to minimize the sum @math{\sum_i (f(x_i, y_i, z_i) - a_i)^2/s_i^2}. At this, approximation function @samp{f} can depend only on one argument @samp{x} (1D case), on two arguments @samp{x,y} (2D case) and on three arguments @samp{x,y,z} (3D case). The function @samp{f} also may depend on parameters. Normally the list of fitted parameters is specified by @var{var} string (like, @samp{abcd}). Usually user should supply initial values for fitted parameters by @var{ini} variable. But if he/she don't supply it then the zeros are used. Parameter @var{print}=@code{true} switch on printing the found coefficients to @var{Message} (@pxref{Error handling}).
++
++Functions Fit() and FitS() do not draw the obtained data themselves. They fill the data @var{fit} by formula @samp{f} with found coefficients and return the @math{\chi^2} error of approximation. At this, the @samp{x,y,z} coordinates are equidistantly distributed in the interval @var{Min}-- at var{Max}. Number of points in @var{fit} is selected as maximal value of @var{fit} size and the value of @var{FitPnts}. Note, that this functions use GSL library and do something only if MathGL was compiled with GSL support. @sref{Fitting sample}

++Class for working with data array. This class is defined in @code{#include <mgl/mgl_data.h>}. The class has functions for easy and safe allocation, resizing, loading and saving, modifying of data arrays. Also it can numerically differentiate and integrate data, interpolate, fill data by formula and so on. Class supports data with dimensions up to 3 (like function of 3 variables - x,y,z). The internal representation of numbers is float. Float type was chosen because it has smaller size in memory and usually it has enough precision in plotting purposes.

Note, that really this ranges are increased by factor 3/2 for purpose of reducing reflection from boundaries. Parameter @var{dz} set the step along evolutionary coordinate z. At this moment, simplified form of function @var{ham} is supported -- all ``mixed'' terms (like @samp{x*p}->x*d/dx) are excluded. For example, in 2D case this function is effectively @math{ham = f(p,z) + g(x,z,u)}. However commutable combinations (like @samp{x*q}->x*d/dy) are allowed. Here variable @samp{u} is used for field amplitude |u|. This allow one solve nonlinear problems -- for example, for nonlinear Shrodinger equation you may set @code{ham="p^2 + q^2 - u^2"}. You may specify imaginary part for wave absorption, like @code{ham = "p^2 + i*x*(x>0)"}, but only if dependence on variable @samp{i} is linear (i.e. @math{ham = hre+i*him}). @sref{PDE sample}

++Solves GO ray equation like dr/dt = d @var{ham}/dp, dp/dt = -d @var{ham}/dr. This is Hamiltonian equations for particle trajectory in 3D case. Here @var{ham} is Hamiltonian which may depend on coordinates @samp{x}, @samp{y}, @samp{z}, momentums @samp{p}=px, @samp{q}=py, @samp{v}=pz and time @samp{t}: @math{ham = H(x,y,z,p,q,v,t)}. The starting point (at @code{t=0}) is defined by variables @var{r0}, @var{p0}. Parameters @var{dt} and @var{tmax} specify the integration step and maximal time for ray tracing. Result is array of @{x,y,z,p,q,v,t@} with dimensions @{7 * int(@var{tmax}/@var{dt}+1) @}.

Parameters @var{ini_re}, @var{ini_im} specify real and imaginary part of initial field distribution. Parameters @var{ray} set the reference ray, i.e. the ray around which the accompanied coordinate system will be maked. You may use, for example, the array created by @code{mglRay()} function.

++
++MathGL library supports (from version 1.3) the simplest scripts for data handling and plotting. These scripts can be used independently (with the help of mgl2png, mgl2eps, mgl2svg programs and others) or in the frame of the library using.
++
++MGL script language is rather simple. Each string is a command. First word of string is the name of command. Other words are command arguments. Command may have up to 1000 arguments (at least for now). Words are separated from each other by space or tabulation symbol. The upper or lower case of words is sufficient, i.e. variables a and A are different variables. Symbol @samp{#} starts the comment (all characters after # will be ignored). The exception is situation when # is a part of some string. Also options can be specified at the end of string (after symbol @samp{;}, @pxref{Command options (MGL)}).
++
++If string contain references to external parameters (substrings @samp{$0}, @samp{$1} ... @samp{$9}) then before execution the values of parameter will be substituted instead of reference. It allows to use the same MGL script for different parameters (filenames, paths, condition and so on).
++
++Argument can be a string, a variable name or a number.
++ at itemize @bullet
++ at item
++The string is any symbols between ordinary marks @samp{'}.
++
++ at item
++Variable name is arbitrary combination of symbols (except spaces and @samp{'}) started from a letter and with length less than 64. It is possible to use sub-arrays (like in @code{subdata} command) as command argument. For example, @code{a(1)} or @code{a(1,:)} or @code{a(1,:,:)} is second row, @code{a(:,2)} or @code{a(:,2,:)} is third column, @code{a(:,:,0)} is first slice and so on. Also you can extract a part of array from m-th to n-th element by code @code{a(m:n,:,:)} or just @code{a(m:n)}.
++
++If names for data columns was specified (by set_id command or in the file at string started with @code{##}) then it is possible to use any column combinations defined by formulas, like @code{a('n*w^2/exp(t)')}.
++
++Also, any expression (without spaces) of existed variables produce temporary variable. For example, @samp{sqrt(dat(:,5)+1)} will produce temporary variable with data values equal to @code{tmp[i,j] = sqrt(dat[i,5,j]+1)}. Such variables can not be used as 1st argument for commands which create (return) the data (like @samp{new}, @samp{read}, @samp{hist} and so on).
++
++ at item
++Special names @code{nan=#QNAN, pi=3.1415926..., on=1, off=0, :=-1} are treated as number if they were not redefined by user. Variables with suffixes are treated as numbers (@pxref{Suffixes}). Also results of formulas with sizes 1x1x1 are treated as number (for example, @samp{pi/dat.nx}).
++ at end itemize
++Before the first using all variables must be defined with the help of commands, like, @code{new, var, list, copy} or @code{read}.
++
++All MGL commands can be divided on several groups. I will use the following notation for a command description: command names are bold, strings are denoted by commas, variable names are italic, numbers are typewriter. Optional arguments are placed in square brackets and default values for them are shown. Detailed description of color, line styles, color schemes, font types, TeX-like symbols and formulas can be found in corresponding section.

It influence only for graphics which created after @code{alpha} call (with one exeption, mglGraphGL). Command @code{alphadef} specify the default value of alpha-channel. You may switch off transparency of selected plot by command @code{transparent}. Finally, command @code{transptype} set the kind of transparency. @sref{Transparent surface sample}
++
++ at deffn {MGL command} alpha @code{[val=on]}
++Sets the transparency on/off. It is recommended to call this command before any plotting command. Default value is @code{off}. Use @code{transparent off} in particular plot to disable its transparency.

++ at end deffn
++ at deffn {MGL command} transptype @code{val}
++This command set the transparency type. Normal transparency (@samp{0}) -- below things is less visible than upper ones. It does not look well in OpenGL mode (mglGraphGL) for several surfaces. Glass-like transparency (@samp{1}) -- below and upper things are commutable and just decrease intensity of light by RGB channel. Lamp-like transparency (@samp{2}) -- below and upper things are commutable and are the source of some additional light. I recommend to set @code{alphadef 0.3} or less for lamp-like transparency.

It influence only for graphics which created after @code{mgl_set_light()} call (with one exeption, mglGraphGL). Generally MathGL support up to 10 independent light sources. But in OpenGL mode only 8 of light sources is used due to OpenGL limitations. The position, color, brightness of each light source can be set separately. By default only one light source is active. It is source number @code{0} with white color, located at top of the plot.
++

++These commands perform plotting of 2D and 3D vector fields. There are 6 generally different types of vector fields representations: simple vector field (Vect), vector field with coloring (VectC), vector field by dew-drops (Dew), flow threads (Flow), flow pipes (Pipe), vectors along a curve (Traj). Each type of plotting has similar interface. There are 2 kind of versions which handle the arrays of data and coordinates or only single data array. Parameters of color scheme are specified by the string argument. @xref{Color scheme}.

++These commands fit data to formula. Fitting goal is to find formula parameters for the best fit the data points, i.e. to minimize the sum @math{\sum_i (f(x_i, y_i, z_i) - a_i)^2/s_i^2}. At this, approximation command @samp{f} can depend only on one argument @samp{x} (1D case), on two arguments @samp{x,y} (2D case) and on three arguments @samp{x,y,z} (3D case). The command @samp{f} also may depend on parameters. Normally the list of fitted parameters is specified by @var{var} string (like, @samp{abcd}). Usually user should supply initial values for fitted parameters by @var{ini} variable. But if he/she don't supply it then the zeros are used.
++
++Commands @code{fit} and @code{fits} do not draw the obtained data themselves. They fill the data @var{out} by formula @samp{f} with found coefficients. At this, the @samp{x,y,z} coordinates are equidistantly distributed in the bounding box. Number of points in @var{out} is selected as maximal value of @var{out} size or 100. Also you may print the last formula with found coefficients by @code{putsfit} command. @sref{Fitting sample}
++
++The dimensions of arrays must be at least the same as the number of specified arrays @var{xdat}, @var{ydat}, @var{zdat}. Also the fitting only along specified directions will be performed (for example, along x and y if only @var{xdat} and @var{ydat} are specified). If array @var{xdat} is not specified then its an automatic array is used with values equidistantly distributed along x.

++Command options allow the easy setup of the plot by changing of global settings only for this plot. Options are specified at the end of string. Each option is separated from the previous text by symbol @samp{;}. Options work so that them remember the current settings, change settings as it being set in the option, execute command and return the original settings back. So, the options usage for data handling commands or for graphics setup commands is useless.
++
++The most useful options are @code{xrange, yrange, zrange}. They sets the boundaries for data change. This boundaries are used for automatically filled variables. So, these options allow one to change the position of some plots. For example, in command @code{plot y; xrange 0.1 0.9} the x coordinate will be equidistantly distributed in range 0.1 ... 0.9.

++MathGL library provides several tools for parsing MGL scripts. There is tools saving it to bitmap (@code{mgl2png}, @code{mgl2gif}) or vectorial (@code{mgl2eps}, @code{mgl2svg}) images. Tool @code{mglview} show MGL script and allow to rotate and setup the image. Also you can translate MGL script to C++ file by help of @code{mgl2cpp} tool.
++
++All of this tools have similar set of arguments. First argument is name of script file, next argument is optional output file name, last arguments are options. There are options for setting script parameters (it is @code{$0, $1, ... $9}) and locale settings. The script parameters have format @samp{-Nval}. Here N=0,1...9 is parameter ID and val is its value. For example, option @samp{-1test} set to substitute @samp{test} instead of @code{$1} in the script. Option -Lval set locale to val. For example, @samp{-Lutf8} will set UTF-8 locale for script.
++
++Additionally you can create animated GIF file or a set of JPEG files with names @samp{frameNNNN.jpg} (here @samp{NNNN} is frame index). You should use @code{mgl2gif} tool and specify the values of @code{$0} parameter for making animation. Values of the parameter @code{$0} can be specified inside the script by comment @code{##a val} for each value @code{val} (one comment for one value) or by option(s) @samp{-Aval}. Tool @code{mgl2gif} will execute script several times (once for each specified value of @code{$0}) and save result in animated GIF file. For saving each frame in JPEG just add command @code{write ''} at the end of the script.

++The class mglGraph (@pxref{MathGL core}) provide the basic tools for creating scientific graphics but it is abstract class. The matter is that there are several possible way to draw a graphics: in bitmap, in vector file, using OpenGL and so on. As result, user should use some of derived classes to do actual drawing. In principle, it is possible to derive a class exactly from mglGraph (and it was in v.1.6). But I recommend to derive from mglGraphAB class for higher compatibility of produced graphics from different classes. Class mglGraphAB is another abstract class which provide basic coordinates transformation, plotting functions and export to bitmap picture. It still require a functions for drawing lines, triangles and quadrangles. So below a set of ``plotter'' classes with short comments.
++
++ at deftp {Class} mglGraphAB
++Abstract class mglGraphAB implements plotting function for 1D, 2D and 3D plots using Z-ordering and provides base functionality for to screen coordinate transformation, bitmap creation and so on. Class is defined in @code{#include <mgl/mgl_ab.h>}.
++ at end deftp
++
++ at deftp {Class} mglGraphZB
++Class mglGraphZB implements plotting function for 1D, 2D and 3D plots using Z-Buffer. It is useful for off-screen (for console or SSH terminal) programs. Also this class can be used in any other programs which may draw bitmap on the screen (for example, by using FLTK, Qt, wxWidgets libraries and so on). Note that bitmap picture is saved while exporting to EPS format. The produced graphics have better quality but slower in comparison with graphics in the class mglGraphPS. Class is defined in @code{#include <mgl/mgl_zb.h>}.
++ at end deftp
++
++ at deftp {Class} mglGraphPS
++Class mglGraphPS implements plotting functions for 1D, 2D and 3D plots and exports them to PostScript or SVG file. It is useful for off-screen (for console or SSH terminal) programs. Note that there is no transparency support now and color interpolation and lightning support is limited (not so nice as in class mglGraphZB). As result the plots with transparency (SurfA, Surf3A, CloudP, CloudQ) may look not so good. However the speed of drawing is higher in comparison with one in the class mglGraphZB. Class is defined in @code{#include <mgl/mgl_eps.h>}.
++ at end deftp
++
++ at deftp {Class} mglGraphGL
++Class mglGraphGL implements plotting function for 1D, 2D and 3D plots under OpenGL. This class can not be used in off-screen applications. Note, that several transparent overlapped surfaces are drawn not so correctly due to OpenGL limitations. Class is defined in @code{#include <mgl/mgl_gl.h>}.
++ at end deftp
++
++ at deftp {Class} mglGraphIDTF
++Class mglGraphIDTF implements plotting function for 1D, 2D and 3D plots and export it in IDTF format. Later this file can be converted in U3D format. Class is defined in @code{#include <mgl/mgl_idtf.h>}.

++Generally this class is a bit less abstract class than mglGraph class (@pxref{MathGL core}). It provide many protected methods for handling intermediate data from mglGraph methods and require a few methods to be defined by derived class. The developers of derived classes should look on file @samp{mgl_ab.h} and comments inside it or contact me.
++
++Here I just show new public methods for class mglGraphAB. There are functions returning the created picture (bitmap), its width and height. You may display it by yourself in any graphical library (see also, @ref{Widget classes}) or save in file (see also, @ref{Export to file}).
++
++ at deftypemethod mglGraphAB @code{const unsigned char *} GetBits ()
++Gets RGB bitmap of the current state of the image. Format of each element of bits is: @{red, green, blue@}. Number of elements is Width*Height. Position of element @{i,j@} is [3*i + 3*Width*j].
++ at end deftypemethod
++
++ at deftypemethod mglGraphAB @code{const unsigned char *} GetRGBA ()
++Gets RGBA bitmap of the current state of the image. Format of each element of bits is: @{red, green, blue, alpha@}. Number of elements is Width*Height. Position of element @{i,j@} is [4*i + 4*Width*j].
++ at end deftypemethod
++
++ at deftypemethod mglGraphAB @code{int} GetWidth ()
++Gets width of the image.
++ at end deftypemethod
++
++ at deftypemethod mglGraphAB @code{int} GetHeight ()
++Gets height of the image.
++ at end deftypemethod
++
++Class mglGraphAB is the base class for ``widget classes''. So there are set of functions for handling window behavior. Most of them are applicable only for ``window'' classes (like mglGraphFLTK and so on, @pxref{Widget classes}). In all other classes these functions just do nothing. You should provide the corresponding interface in derived ``widget'' classes for user convenience.
++
++ at deftypemethod mglGraphAB @code{void} Window (@code{int} argc, @code{char **}argv, @code{int (*}draw)(@code{mglGraph *}gr, @code{void *}p), @code{const char *}title, @code{void *}par=@code{NULL}, @code{void (*}reload)(@code{int} next, @code{void *}p)=@code{NULL}, @code{bool} maximize=@code{false})
++This function creates a window for plotting. Parameters @var{argc}, @var{argv} contain OS specific information and should be the same as in function @code{main(int argc,char **argv)}. Parameter @var{draw} sets a pointer (this is the name of function) to drawing function. There is support of a list of plots (frames). So as one can prepare a set of frames at first and redraw it fast later (but it requires more memory). Function should return positive number of frames for the list or zero if it will plot directly. Note, that @var{draw} can be @code{NULL} for displaying static bitmaps only (no animation or slides). Parameter @var{title} sets the title of the window. Parameter @var{par} contains pointer to data for the plotting function @var{draw}. Parameter @var{maximize}=@code{true} open maximized window.
++
++There are some keys handles for manipulating by the plot: 'a', 'd', 'w', 's' for the rotating; ',', '.' for viewing of the previous or next frames in the list; 'r' for the switching of transparency; 'f' for the switching of lightning; 'x' for hiding (closing) the window.
++
++ at strong{IMPORTANT!!!} You need to add a call of Rotate() (@pxref{Transformation matrix}) function for having possibility of plot rotation. If plot should be unrotated by default just add @code{Rotate(0,0)} in drawing function.

++
++ at deftypemethod mglGraphAB @code{void} Window (@code{int} argc, @code{char **}argv, @code{mglDraw *}draw, @code{const char *}title, @code{bool} maximize=@code{false})
++This function is mostly the same as previous one. The only difference is that the drawing function and function for data reloading are specified as methods on a class inherited from class @code{mglDraw}. This class is defined in @code{#include <mgl/mgl_data.h>} and have only 2 methods:
++ at verbatim
++class mglDraw
++{
++public:
++ virtual int Draw(mglGraph *) { return 0; };
++ virtual void Reload(int) {};
++};

++Class for parsing and executing MGL script. This class is defined in @code{#include <mgl/mgl_parse.h>}.
++
++Class mglParse is the interpreter for MGL scripts (@pxref{MGL interface}). The main function of mglParse class is @code{Parse()}. Exactly this function parses and executes the script string-by-string. Also there are two subservient functions for the finding and creation of a variable. These functions can be useful for displaying values of variables (arrays) in some external program (in window, for example). The variable @var{DataList} contains full list of variables in script. Flag @var{AllowSetSize} allows one to prevent changing the size of the picture inside the script (forbids the MGL command @code{setsize}).
++
++Note an important feature -- if user defines function @var{func} in variable then it will be called before the destroying of this variable (@pxref{mglVar class}).
++
++ at deftypemethod mglParse @code{} mglParse (@code{bool} setsize=@code{false})
++Constructor initializes all values with zero and set @var{AllowSetSize} value.

++Main function in the class. It parses the string @var{str} and executes it by using @var{gr} as a graphics plotter. Returns the value depending on an error presence in the string @var{str}: 0 -- no error, 1 -- wrong command argument(s), 2 -- unknown command, 3 -- string is too long. Optional argument @var{pos} allows to save the string position in the document (or file) for using @code{for|next} command.

++
++Class for working with font: load, get metrics, parse and draw strings. This class is defined in @code{#include <mgl/mgl_font.h>}.
++
++The class is based on loading and drawing of vector Hershey font. There are two styles of specifying of the font type and aligning: by integer parameters or by string.
++
++The string can be any combination of characters: @samp{rbiLCRwou}. The font types are: @samp{r} -- roman font, @samp{i} -- italic style, @samp{b} -- bold style. By default roman font (that is @samp{} or @samp{r}) is used. The align types are: @samp{L} -- align left (default), @samp{C} -- align center, @samp{R} -- align right. Additional font effects are: @samp{w} -- wire, @samp{o} -- over-lined, @samp{u} -- underlined.
++
++The over way of font and alignment setting is the using of the integer constant. Integer font Id can be one of predefined constants: @code{MGL_FONT_ITAL, MGL_FONT_BOLD, MGL_FONT_BOLD_ITAL = MGL_FONT_ITAL+MGL_FONT_BOLD}. Default font is @code{MGL_FONT_ROMAN}. Also there are flags @code{MGL_FONT_ULINE, MGL_FONT_OLINE, MGL_FONT_WIRE} for additional font effects. Align parameter controls the text alignment: 0 -- align left, 1 -- align center, 2 -- align right.
++
++Parsing of the string to special (TeX-like) commands will be done if variable @var{parse} is true (it's default). There are commands for the font style changing inside the string (for example, use \b for bold font): \a or \overline -- over-lined, \b or \textbf -- bold, \i or \textit -- italic, \r or \textrm -- roman (disable bold and italic attributes), \u or \underline -- underlined, \w or \wire -- wired, \big -- bigger size, @@ -- smaller size. The lower and upper indexes are specified by @samp{_} and @samp{^} symbols. At this the changed font style is applied only on next symbol or symbols in braces @{@}. The text in braces @{@} are treated as single symbol that allow one to print the index of index. For example, compare the strings @samp{sin (x^@{2^3@})} and @samp{sin (x^2^3)}. You may also change text color inside string by command #? or by \color? where @samp{?} is symbolic id of the color (@pxref{mglColor class}). For example, words @samp{Blue} and @samp{red} will be colored in the string @samp{#b@{Blue@} and \colorr@{red@} text}.
++
++The most of commands for special TeX or AMSTeX symbols, the commands for font style changing (\textrm, \textbf, \textit, \overline, \underline), accents (\hat, \tilde, \dot, \ddot, \acute, \check, \grave, \bar, \breve) and roots (\sqrt, \sqrt3, \sqrt4) are recognized. The full list contain approximately 2000 commands. Note that first space symbol after the command is ignored, but second one is printed as normal symbol (space). For example, the following strings produce the same result @math{\tilde a}: @samp{\tilde@{a@}}; @samp{\tilde a}; @samp{\tilde@{@}a}.

++ at subsection Format of font files
++
++Starting from v.1.6 the MathGL library uses new font files. The font is defined in 4 files with suffixes @samp{*.vfm}, @samp{*_b.vfm}, @samp{*_i.vfm}, @samp{*_bi.vfm}. These files are text files containing the data for roman font, bold font, italic font and bold italic font. The files (or some symbols in the files) for bold, italic or bold italic fonts can be absent. In this case the roman glyph will be used for them. By analogy, if the bold italic font is absent but the bold font is present then bold glyph will be used for bold italic. You may create these font files by yourself from *.ttf, *.otf files with the help of program @code{font_tools}. This program can be found at MathGL home site.
++
++The format of font files (*.vfm -- vector font for MathGL) is the following.
++ at enumerate
++ at item
++First string contains human readable comment and is always ignored.
++ at item
++Second string contains 3 numbers, delimited by space or tabulation. The order of numbers is the following: @var{numg} -- the number of glyphs in the file (integer), @var{fact} -- the factor for glyph sizing (float), @var{size} -- the size of buffer for glyph description (integer).
++ at item
++After it @var{numg}-th strings with glyphs description are placed. Each string contains 6 positive numbers, delimited by space of tabulation. The order of numbers is the following: Unicode glyph ID, glyph width, number of lines in glyph, position of lines coordinates in the buffer (length is 2*number of lines), number of triangles in glyph, position of triangles coordinates in the buffer (length is 6*number of triangles).
++ at item
++The end of file contains the buffer with point coordinates at lines or triangles vertexes. The size of buffer (the number of integer) is @var{size}.
++ at end enumerate
++
++Note: the closing contour line is done automatically (so the last segment may be absent). For starting new contour use a point with coordinates @code{@{0x3fff, 0x3fff@}}.
++

++ at section mglColor class
++ at cindex mglColor
++
++Structure for working with colors. This structure is defined in @code{#include <mgl/mgl.h>}.
++
++There are two ways to set the color in MathGL. First one is using of float values of red, green and blue channels for precise color definition. The second way is the using of character id. There are a set of characters specifying frequently used colors. Normally capital letter gives more dark color than lowercase one. The full list of characters is: @samp{k} -- black, @samp{r} -- red, @samp{R} -- dark red, @samp{g} -- green, @samp{G} -- dark green, @samp{b} -- blue, @samp{B} -- dark blue, @samp{c} -- cyan, @samp{C} -- dark cyan, @samp{m} -- magenta, @samp{M} -- dark magenta, @samp{y} -- yellow, @samp{Y} -- dark yellow (gold), @samp{h} -- gray, @samp{H} -- dark gray, @samp{w} -- white, @samp{W} -- bright gray, @samp{l} -- green-blue, @samp{L} -- dark green-blue, @samp{e} -- green-yellow, @samp{E} -- dark green-yellow, @samp{n} -- sky-blue, @samp{N} -- dark sky-blue, @samp{u} -- blue-violet, @samp{U} -- dark blue-violet, @samp{p} -- purple, @samp{P} -- dark purple, @samp{q} -- orange, @samp{Q} -- dark orange (brown).
++
++Also you may use ``lighted'' colors in color scheme specification (@emph{not in line style!}). The ``lighted'' color contain 2 symbols: first one is usual symbol for color specification, second one is digit for its brightness. The digit can be in range @samp{1}... at samp{9}. At this @samp{5} correspond to normal color, @samp{1} is very dark version of the color (practically black), @samp{9} is very bright version of the color (practically white).

++
++The code for making high-quality scientific graphics under Linux and Windows. The code for the fast handling and plotting of large data arrays. The code for working in window and console regimes and for easy including into another program. The code with large and renewal set of graphics. Exactly such code I was looking for during last years. Exactly such code I tried to realize in MathGL library.
++
++At this version (@value{VERSION}) MathGL has more than 20000 code strings, more than 40 general types of graphics for 1d, 2d and 3d data arrays. It can export graphics to bitmap and vector (EPS or SVG) files. It has OpenGL interface and can be used from console programs. It has functions for data handling and script MGL language for simplification of data plotting. Also it has several types of transparency and smoothed lightning, vector fonts and TeX-like symbol parsing, arbitrary curvilinear coordinate system and many over useful things (see pictures section at @uref{http://mathgl.sf.net/, homepage}). Finally it is a platform independent and free (under GPL v.2.0 or later license).
++
++ at node MathGL features, Installation and using, Why I have written MathGL?, Overview

++
++MathGL can plot wide range of graphics. It includes:
++ at itemize @bullet
++ at item
++one-dimensional (Plot, Area, Bars, Step, Stem, Torus, Chart, Error, Tube, Mark, @pxref{1D plotting});
++
++ at item
++two-dimensional plots (Mesh, Surf, Dens, Cont, ContF, Boxs, Axial, Fall, Belt, Tile, @pxref{2D plotting});
++
++ at item
++three-dimensional plots (Surf3, Dens3, Cont3, ContF3, Cloud-like, @pxref{3D plotting});
++
++ at item
++dual data plots: vector fields Vect and VectC, flow threads Flow, mapping chart Map, surfaces and isosurfaces transpared or colored (i.e. its transparency or color is depend on) by other data SurfA, SurfC, Surf3A, Surf3C (@pxref{Dual plotting});
++
++ at item
++and so on. For detail @xref{MathGL core}.
++ at end itemize
++
++In fact, I created functions for drawing of all scientific plots that I know. The list of plots is enlarging, so if you need some special type of plot then write me @email{mathgl.abalakin@@gmail.com, e-mail} and it will appear in new version.
++
++I tried to make plots as well-looking as possible: surface can be transparent and highlighted by several (up to 10) light sources. Most of drawing functions have 2 variants: simple one for the fast plotting of data, complex one for specifying of the exact position of plot (including parametric representation). Resulting image can be saved in bitmap (with the help of mglGraphZB, mglGraphGL) PNG, JPEG, TIFF, BMP format or in vector EPS or SVG format (with the help of mglGraphPS), or in IDTF format (with the help of mglGraphIDTF) which can be converted in U3D.
++
++All text are drawn by vector font, that allows high scalability and portability. Text may contain commands for: some of TeX-like symbols, changing index (upper or lower indexes) and style of font inside the text string (@pxref{mglFont class}). Texts of ticks are rotated with axis rotation. It is possible to create a legend of plot and put text in arbitrary position of plot. An arbitrary text encoding (by help of function @code{setlocale()}) and UTF-16 encoding are supported.
++
++Special mglData class is used for data encapsulation (@pxref{mglData class}). Except safe creation and deletion of data arrays it includes functions for data processing (smoothing, differentiating, integrating, interpolating and so on) and reading of data files with automatic size determination. Class mglData can handle arrays with up to three dimensions (arrays which depend up to 3 independent indexes @math{a_@{ijk@}}). Using an array with higher number of dimensions is not reasonable because I do not know how it can be plotted. Data filling and modifying may be fulfilled manually or by textual formulas.
++
++Class mglFormula class allows the fast evaluation of a textual mathematical expression (@pxref{mglFormula class}). It is based on string precompilation to tree-like code at creation of class instance. At evaluation stage code performs only fast tree-walk and returns the value of the expression. Except changing data values, textual formulas are used for drawing in @emph{arbitrary} curvilinear coordinates. A set of such curvilinear coordinates is limited only by user imagination but not a fixed list like polar, parabolic, spherical and so on.

++ at node Installation and using, General concepts, MathGL features, Overview
++ at section Installation and using
++
++MathGL can be installed by 3 ways.
++ at enumerate
++ at item
++Compile from sources. The standard script for autoconf/automake tools is included in library beginning from version 1.2.1. For its running one should execute 3 commands: @code{./configure} after it @code{make} and @code{make install} with root/sudo rights. Script @code{./configure} have several additional options which is switched off by default. They are: @code{--enable-fltk, --enable-glut, --enable-qt} for ebabling FLTK, GLUT and/or Qt windows; @code{--enable-jpeg, --enable-tiff, --enable-hdf5} for enabling corresponded file formats; @code{--enable-all} for enabling all additional features. The full list of options can be viewed by command @code{./configure --help}.
++ at item
++Use precompiled binary. There are binaries for MinGW (platform Win32). For precompiled variant one needs only to unpack the archive to the compiler location (or in any other folder and setup paths). By default precompiled versions include the support of GSL (www.gsl.org) and PNG. So, one needs to have these libraries installed on system.
++ at item
++Install precompiled versions from standard packages (RPM, deb, DevPak and so on, see @uref{http://mathgl.sf.net/download.html, Download} section at homepage).
++ at end enumerate
++
++At the own program compilation one needs to specify the linker key @code{-lmgl} for compilation in console program or with the external (not MathGL) window library. If one wants to use FLTK or GLUT windows then he needs to add the keys @code{-lmgl-fltk} or @code{-lmgl-glut}. Fortran users also should add C++ library by option @code{-lstdc++}.

++The set of MathGL features is rather reach -- just the number of basic graphics types is more than 40. Also there are functions for data handling, plot setup and so on. In spite of it I tried to keep the similar style in function names and in the order of arguments. Mostly it is regarded for different drawing functions.
++
++There are six most general (base) concepts:
++ at enumerate
++ at item
++ at strong{Any picture is created in memory firstly.} The internal (memory) representation can be different: bitmap picture or the list of vector primitives. After it user may decide what he want: save to file, display on the screen, run animation, do additional editing and so on. This approach provides high portability of the program -- the source code will produce exactly the same picture in @emph{any} OS. Another big positive consequence is the ability to create the picture in console program (without window creating)!
++ at item
++ at strong{Every plot settings (style of lines, font, color scheme) are specified by string.} It provides convenience for user/programmer -- short string with parameters is more comprehensible than a large set of parameters. Also it provides portability -- the strings are the same in any OS so that it is not comprehensible to think about type of arguments.
++ at item
++ at strong{All functions have ``simplified'' and ``advanced'' forms.} It is done for user convenience. One needs to specify the only one data array in ``simplified'' form and will see the result. But one may set parametric dependence of coordinates and produce rather complex curves and surfaces in ``advanced'' form. In both cases the order of function arguments are the same: firstly data arrays, secondly the string with plot parameters, and later optional arguments for plot tunning.
++ at item
++ at strong{All data arrays for plotting are encapsulated in class mglData class.} It reduces the number of errors with memory working and provide the uniform interface for data of different types (float, double and so on) or for formulas plotting.
++ at item
++ at strong{All plots are vector plot.} The MathGL library is intended for handling scientific data which have vectorial nature (there are lines, faces, matrices and so on). As result vectorial representation is used in any cases! In addition the vectorial representation allows one to scale easily the plot -- change the canvas size by 2 times and the picture will proportionally scaled.
++ at item
++ at strong{New drawing never clears things drawn already.} This, in some sense, is unexpected, idea allows to create a lot of ``combined'' graphics. For example, for making a surface with contour lines one need to call the function of surface plotting and the function of contour lines plotting (in any order). At this the special functions (as it done in Matlab and some other plotting system) for making this ``combined'' plots are useless. Much more examples of such plots can be found in section @ref{Hints} and in home site (@uref{http://mathgl.sf.net/index.html}).

++Except general concept I want consider on some non-trivial or non-usual general ideas -- plot positioning, axis specification and curvilinear coordinates, styles for lines, text and color scheme.

++ at subsection Coordinate axes
++
++There is twofold axes representation in MathGL. First one consists in normalizing of the data point coordinates in box @var{Min}x at var{Max} (@pxref{Axis settings}). If @var{Cut} is @code{true} then the outlied points are omitted otherwise they are projected to the bounding box (@pxref{Cutting}). Also, the point will be omitted if it lies inside the box defined by @var{CutMin}x at var{CutMax} or if the value of formula @code{CutOff}() is nonzero for its cooridnates. After it transformation formulas are applied to the data point (@pxref{Transformation}). Finally, the data point is plotted by one of function.
++
++There is possibility to set members @var{Max}, @var{Min} directly but one should call @code{RecalcBorder()} function to setup plotting routines. The more safe way is to set these values by calling @code{Axis()} function. In this case the function @code{RecalcBorder()} is called automatically. Another way to specify the size of axis is to set it as a minimal or maximal value of data array. Functions @code{XRange(), YRange(), ZRange()} do it. The second (optional) argument sets to replace the axis range or to join with the existed range.
++
++The axis origin is defined by variable @var{Org} and is applied for all consequent calls of axes or grid drawing. By default, if this point lies outside the bounding box then it is projected to the one (variable @var{AutoOrg} control it). In the case if one of values of @var{Org} is equal to NAN then the corresponding value will be selected automatically.
++
++There is 4-th axis @emph{c} (color axis or colorbar) in addition to usual axes @emph{x, y, z}. It sets the range of values for the surface coloring. Its borders are automatically set to values of Min.z, Max.z during the call of @code{Axis()} function. Also, there are direct change of the color range by setting of variables @var{Cmax}, @var{Cmax}, or calling functions @code{CAxis()} or @code{CRange()}. Use @code{Colorbar()} function for showing the colorbar.
++
++The form (appearence) of tick labels is controlled by @code{SetTicks()} function and few variables (@pxref{Ticks}). It have 3 arguments: first one @var{d} set the tick step (if positive) or tick number (if negative) or switch logarithmic ticks on (if zero); second one @var{ns} set the number of subticks; last one is the starting point for ticks (default is axis origin). The variable @var{TuneTicks} switches on/off ticks enhancing by the detaching of the common multiplier (for small, like from 0.001 to 0.002, or large, like from 1000 to 2000, coordinate values) or common component (for narrow range, like from 0.999 to 1.000). Finally, you may use variables @var{xtt}, @var{ytt}, @var{ztt}, @var{ctt} for setting templates for tick labels (it supports TeX symbols). Also, there is a possibility to print arbitrary text as tick labels if one defines the pointer (name) of function @var{TickStr}.

++ at node Line styles, Color scheme, Coordinate axes, General concepts
++ at subsection Line styles
++
++ at cindex Line style
++ at cindex Mark style
++ at cindex Arrows
++
++The line style is defined by the string which may contain specifications for color (@samp{wkrgbcymhRGBCYMHWlenupqLENUPQ}), dashing style (@samp{-|;:ji} or space), width (@samp{0123456789}) and marks (@samp{o+xsd.^v} and @samp{#} modifier). If one of type of information is omitted then default values with the previous color are used.
++
++The color types are the same as described in mglColor class (@pxref{mglColor class}): @samp{k} -- black, @samp{r} -- red, @samp{R} -- dark red, @samp{g} -- green, @samp{G} -- dark green, @samp{b} -- blue, @samp{B} -- dark blue, @samp{c} -- cyan, @samp{C} -- dark cyan, @samp{m} -- magenta, @samp{M} -- dark magenta, @samp{y} -- yellow, @samp{Y} -- dark yellow (gold), @samp{h} -- gray, @samp{H} -- dark gray, @samp{w} -- white, @samp{W} -- bright gray, @samp{l} -- green-blue, @samp{L} -- dark green-blue, @samp{e} -- green-yellow, @samp{E} -- dark green-yellow, @samp{n} -- sky-blue, @samp{N} -- dark sky-blue, @samp{u} -- blue-violet, @samp{U} -- dark blue-violet, @samp{p} -- purple, @samp{P} -- dark purple, @samp{q} -- orange, @samp{Q} -- dark orange (brown).
++
++Dashing styles has the following meaning: space -- no line (usable for plotting only marks), @samp{-} -- solid line (################), @samp{|} -- dashed line (########________), @samp{;} -- small dashed line (####____####____), @samp{:} -- dotted line (#___#___#___#___), @samp{j} -- dash-dotted line (#######____#____), @samp{i} -- small dash-dotted line (###__#__###__#__).
++
++Marker types are: @samp{o} -- circle, @samp{+} -- cross, @samp{x} -- skew cross, @samp{s} - square, @samp{d} - rhomb (or diamond), @samp{.} -- point, @samp{^} -- triangle up, @samp{v} -- triangle down. If string contain symbol @samp{#} then the solid versions of markers are used.

++ at float
++ at image{png/sample5, 7cm}
++ at caption{Styles of lines and marks.}
++ at end float
++
++One may specify to draw a special symbol (an arrow) at the beginning and at the end of line. It is possible if the specification string contains one of the following symbols: @samp{A} -- outer arrow, @samp{V} -- inner arrow, @samp{I} -- transverse hachures, @samp{K} -- arrow with hachures, @samp{T} -- triangle, @samp{S} -- square, @samp{D} -- rhomb, @samp{O} -- circle, @samp{_} -- nothing (it is default). At this, there is a rule: first symbol specifies the arrow at the end of line, second one specifies the arrow at the beginning of line. For example, @samp{r-A} defines a red solid line with usual arrow at the end, @samp{b|AI} defines a blue dash line with an arrow at the end and with hachures at the start, @samp{_O} defines a line with the current style and with a circle at the start. These styles are applicable during the graphics plotting too (for example, @ref{Plot}).

++
++ at node Color scheme, Font style, Line styles, General concepts
++ at subsection Color scheme
++
++ at cindex Color scheme
++
++The color scheme is used for determining the color of surfaces, isolines, isosurfaces and so on. The color scheme is defined by the string which may contain several characters that are color id (@pxref{mglColor class} or @pxref{Line styles}) or characters @samp{d#:|}. Symbol @samp{d} denotes interpolation by 3d position instead of the coloring by amplitude. Symbol @samp{#} switch to mesh drawing or to wire plot. Symbol @samp{|} disable color interpolation in color scheme which can be usefull, for example, for sharp colors during matrix plotting. Symbol @samp{:} finishes the color scheme parsing. After it the user may put styles for text, rotation axis for curves/isolines and so on. Color scheme may contain up to 32 color values.
++
++Also you may use ``lighted'' colors in color scheme specification (@emph{not in line style!}). The ``lighted'' color contain 2 symbols: first one is usual symbol for color specification, second one is digit for its brightness. The digit can be in range @samp{1}... at samp{9}. At this @samp{5} correspond to normal color, @samp{1} is very dark version of the color (practically black), @samp{9} is very bright version of the color (practically white).
++
++ at float
++ at image{png/colors, 7cm}
++ at caption{Colors and its ids.}
++ at end float
++
++For coloring by @emph{amplitude} (most common) the final color is linear interpolation of color array. The color array is constructed from the string ids. The argument is the amplitude normalized between @var{Cmin} -- @var{Cmax} (@pxref{Ranges (bounding box)}). For example, string containing 4 characters @samp{bcyr} corresponds to colorbar from blue (lowest value) through cyan (next value) through yellow (next value) to the red (highest value). String @samp{kw} corresponds to colorbar from black (lowest value) to white (highest value). String @samp{m} corresponds to a simple magenta color.
++
++There are several useful combinations. String @samp{kw} corresponds to the simplest gray color scheme when higher values are brighter. String @samp{wk} presents the inverse gray color scheme when higher value is darker. Strings @samp{kRryw}, @samp{kGgw}, @samp{kBbcw} present well-known @emph{hot}, @emph{summer} and @emph{winter} color schemes. Strings @samp{BbwrR} and @samp{bBkRr} allow to view bicolor figure on white or black background when negative values are blue and positive values are red. String @samp{BbcyrR} gives color scheme similar to well-known @emph{jet} color scheme.

++ at end table
++
++For the coloring by @emph{coordinate} the final color is determined by position of the point in 3d space and is calculated by formula c=x*c[1] + y*c[2] + z*c[3]. Here c[1], c[2], c[3] are the first three elements of color array; x, y, z are normalized to @var{Min} -- @var{Max} coordinates of the point. This type of coloring is useful for isosurface plot when color may show the exact position of the peace of surface. For example, @pxref{Surf3}.
++
++Also you may use ``lighted'' colors in color scheme specification (@emph{not in line style!}). The ``lighted'' color contain 2 symbols: first one is usual symbol for color specification, second one is digit for its brightness. The digit can be in range '1'...'9'. At this @samp{5} correspond to normal color, @samp{1} is very dark version of the color (practically black), @samp{9} is very bright version of the color (practically white). For example, the color scheme can be @samp{b2b7wr7r2}.
++
++ at node Font style, , Color scheme, General concepts
++ at subsection Font style
++
++ at cindex Font style
++
++Text style is specified by the string which may contain several characters of font (@samp{ribwou}) and/or align (@samp{LRC}) specifications. The string also may contain the color id characters @samp{wkrgbcymhRGBCYMHW} (@pxref{mglColor class}) after the symbol @samp{:}. For example, @samp{biC:b} sets the bold italic font text aligned at the center and with blue color.
++
++The font types are: @samp{r} -- roman font, @samp{i} -- italic style, @samp{b} -- bold style. By default roman roman font is used. The align types are: @samp{L} -- align left (default), @samp{C} -- align center, @samp{R} -- align right. Additional font effects are: @samp{w} -- wired, @samp{o} -- over-lined, @samp{u} -- underlined. Also a parsing of the LaTeX-like syntax is provided (for detail, @pxref{mglFont class} and @ref{Font settings}).
++
++The font size can be defined explicitly (if @var{size}>0) or relatively the base font size as |@var{size}|*@var{FontSize} (if @var{size}<0). The value @var{size}=0 specifies that the string will not be printed. The base font size is measured in internal ``MathGL'' units. Special functions @code{SetFontSizePT(), SetFontSizeCM(), SetFontSizeIN()} allow one to set it in more ``common'' variables for given dpi of the picture.

++ at item The plot does not appear
++Check that points of the plot lie inside the bounding box and resize the bounding box by @code{Axis()} function. Check that the data have correct dimensions for selected type of plot. Be sure that @code{Finish()} is called after the plotting functions (or be sure that the plot is saved to file).
++
++ at item I can not find some special kind of plot.
++Most of ``new'' type of plot can be created by using of the existing drawing functions. For example, the surface of curve rotation can be created by special function @code{Torus()} or as parametrically specified surface @code{Surf()}. See also, @ref{Hints} and @ref{Examples} of MathGL. If you can not find some type of plot then e-mail me and this plot will appear in the next version of MathGL library.
++
++ at item Should I know some graphical libraries (like OpenGL) for the using of MathGL library?
++No. The MathGL library is self-consistent and does not require the knowledge of external libraries.
++
++ at item In which language the library is written? For which languages the library has interface?
++The core of MathGL library is written on C++. But there are interfaces for pure C, Fortran, Pascal, Forth languages and its own command language MGL. Also there are a large set of interpreter languages support (Python, Java, ALLEGROCL, CHICKEN, Lisp, CFFI, C#, Guile, Lua, Modula 3, Mzscheme, Ocaml, Octave, Perl, PHP, Pike, R, Ruby, Tcl). These interfaces are written via SWIG (both pure C functions and classes) but only interface for Python and Octave is included in autoconf/automake script. The matter that I don't know any other interpreter languages :(. Note, the most of other languages can use (can link) pure C functions.
++
++ at item How I can use MathGL with Fortran?
++You can use MathGL as is with @code{gfortran} because it use by default AT&T notation for external functions. For other compilers (like, Visual Fortran) you have to switch on AT&T notation manually. The AT&T notation require that symbol @samp{_} is added at the end of function name, function argument(s) is passed by pointers and string length(s) is passed at the end of argument list. For example:
++
++ at emph{C function} -- @code{void mgl_fplot(HMGL graph, const char *fy, const char *stl, int n);}
++
++ at emph{AT&T function} -- @code{void mgl_fplot_(uintptr_t *graph, const char *fy, const char *stl, int *n, int ly, int ls);}
++
++ at item I have class Foo and drawing method Foo::draw(mglGraph *gr). How I can use it in FLTK or GLUT window?
++The member-functions of classes have hidden parameter (the pointer to a class instance) in C++. So, their direct usage is impossible. The solution is to write interface function:
++ at example
++int foo_draw(mglGraph *gr, void *par)
++@{ ((Foo *)foo)->draw(gr); @}
++ at end example
++and to use it in the call of @code{Window()} function:
++ at example
++gr->Window(argc,argv,foo_draw,"Title",this);
++ at end example
++
++Alternatively you can inherit yours class from @code{mglDraw} class and use functions like @code{gr->Window(argc, argv, foo, "Title");}.
++
++ at item How can I print in Russia/Spanish/Arabian/Japanese and so on?
++The standard way is the using of Unicode encoding for the text output. But MathGL library also has interface for 8-bit (char *) strings with internal conversion to Unicode. This conversion depends on the current locale OS. You may change it by @code{setlocale()} function. For example, for Russian text in CP1251 encoding you may use @code{setlocale(LC_CTYPE, "ru_RU.cp1251");} (under MS Windows the name of locale may differ -- @code{setlocale(LC_CTYPE, "russian_russia.1251")}). I strongly recommend not to use the constant @code{LC_ALL} in conversion. Because it also changes the number format that may lead to mistakes in formulas writing and reading textual data files. For example, the program will await a @samp{,} as a decimal point but the user will enter @samp{.}.
++
++ at item How can I exclude a point or a region of plot from the drawing?
++There are 3 general ways. First, the point with @code{NAN} value of one of coordinate will never be plotted. Second, special variables @var{CutMin}, @var{CutMax} or function @code{CutOff}() define the condition when the points should be omitted (@pxref{Cutting}). Last, you may change the transparency of part of the plot by the help of functions @code{SurfA()}, @code{Surf3A()} (@pxref{Dual plotting}). In last case the transparency is switched on smoothly.
++
++ at item I use VisualStudio, CBuilder or some other compiler (not MinGW/gcc). How can I link MathGL library?
++There are 2 ways. First is use the precompiled binary (*.dll). In this case you should make libraries for yours compiler from *.dll and *.def files. The corresponding command may look like @code{lib.exe /def:libmgl.def}. But such way provide you only pure C functions, not C++ classes. The matter is that there is no standard for C++ functions naming in object files. The standard was accepted only for C functions.
++
++The second way is to compile the library from sources. MathGL library have some external dependencies (PNG, GSL, JPEG, TIFF, FLTK, GLUT, HDF5), but most of them is optional. Some libraries can be found @uref{https://sourceforge.net/project/showfiles.php?group_id=152187&package_id=267177, here}. But also you may exclude from the project the corresponding files to disable usage of JPEG, TIFF, FLTK, GLUT, HDF5 libraries. Also you may define @code{NO_GSL} at compilation stage for disabling GSL support. At this some special functions in formulas, Fourier transform and nonlinear fitting will be disabled also.
++
++For excluding PNG support just comment the body of functions @code{mgl_pnga_save(), mgl_png_save()} in @code{mgl_export.cpp}. After it MathGL library will not depend on any external libraries. But in this case you should redirect the output to some window (as bitmap drawing from mglGraphZB|PS::GetBits() or mglGraphZB|PS::GetRGBA()) and save this bitmap to a file by yourself.
++
++ at strong{Finally!} Please @emph{do not} ask me Windows-specific questions. I do not use Windows. I know nothing about Visual Basic, Visual C++, CBuiled or .NET. Please find the appropriate Usenet discussion group and ask your question there.
++
++ at item How many people write this library?
++The most of the library was written by one person. This is result of near a year of work (mostly in the evening and in holidays): half-year I spent for writing the kernel and half-year or year I spent for extending, improving and documentation writing. This process continues now :). The autoconf/automake script was written mostly by D.Kulagin, and export to IDTF was written mostly by M.Vidassov. Packages to particular platform (RPM or DEB) are prepared by other people (thanks to D. Kulagin, S. Plis, V. Lipatov and N. Troitsky).
++
++ at item How can I display a bitmap?
++You can import data into a mglData instance and display it by Dens() function. For example, for black-and-white bitmap you can use the code: @code{mglData bmp; bmp.Import("fname.png","wk"); gr->Dens(bmp,"wk");}.
++
++ at item How can I use MathGL in Qt, FLTK, wxWidgets ...?
++There are special classes (widgets) for these libraries: QMathGL for Qt, Fl_MathGL for FLTK and so on. If you don't find the appropriate class then you can create yours own widget which display a bitmap from mglGraphAB::GetBits().
++
++ at item How can I create U3D file (make 3D in PDF)?
++There are 2 steps: first you should create IDTF file, and later convert it to U3D. You can use @uref{http://sourceforge.net/project/showfiles.php?group_id=152187&package_id=300628, U3D tools} for converting IDTF file to U3D. It need @uref{http://libharu.org, libharu} 2.1.0 or later. For installation use @code{./bootstrap, ./configure, make, sudo make install}. It provide IDTFConverter program for converting textual files *.idtf to binary files *.u3d. Last ones can be included into PDF.
++
++ at item How I can change font family?
++First, you should download new font files from @uref{http://mathgl.sourceforge.net/download.html, here} or from @uref{http://sourceforge.net/project/showfiles.php?group_id=152187&package_id=267177, here}. Next, you should load font files into mglGraph class instance @var{gr} by following command: @code{gr->SetFont(new mglFont(fontname,path));}. Here @var{fontname} is base font name like @samp{STIX} and @var{path} set the location of font files. Use @code{gr->SetFont(NULL);} for using default font.
++
++ at item How can I draw tick out of bounding box?
++Just set negative value for @var{TickLen}. For example, use @code{gr->SetTickLen(-0.1);}.
