| Ok this is a real bug and is present in both 3.0.1+ and 3.1.51+. The fix

Did you have a chance to look at this?  I don't see how to make the x2
tic labels appear in a plot like this.  The pcolor plot uses splot,
and the following

  set view map
  set x2tics
  splot x+y

does not display the x2 tic labels.  I am able to control the x and y
tics, but not the x2 and y2 tics.  That looks like it might be a bug
in gnuplot.  I'm using 4.2.2.  Can someone check with the current
gnuplot development sources?

Thanks,
