[Pkg-octave-devel] Bug#297028: octave-forge: Missing depends on grace, switching back to gnuplot hard

[Dennis Jørgensen]

Package: octave-forge
Version: 2004.11.16-5
Severity: important


The new octave-forge made grace the default for plotting, without
depending on it, which octave doesn't like at all:

octave:1> x=linspace(-pi,pi,100);
octave:2> plot(x,sin(x))
grplot: Cannot start xmgrace

grplot:No grace subprocess
Segmentation fault


Installing grace fixes plotting of a single plot, but "hold on" doesn't work.
Installing grace6 just gives blank plots.

(Results based on very little testing)


Turning of grace seems hard:

octave:1> toggle_grace_use 
error: /usr/share/octave/2.1.65/site/octave-forge-alternatives/m/graceplot: No such file or directory
error: near line 55 of file `/usr/share/octave/site/m/octave-forge/graceplot/toggle_grace_use.m'

Looking at the code of toggle_grace_use made me aware of grace_octave_path:

octave:1> grace_octave_path('/usr/share/octave/site/m/octave-forge/graceplot/');octave:2> toggle_grace_use 
Use Grace: off
octave:3>

But if I plot something after this, grace still comes up. I don't
know if this is because I'm using grace_octave_path in the wrong
way, but then I guess toggle_grace_use should have failed again.
