Follow-up Comment #1:

Thank you for your bug report. First and foremost, can you confirm whether you
are using the gnuplot or qt toolkit? The script that you attached to this
report has both toolkits selected, are you commenting out one or the other
when you run? Is this a mistake that you left the second line in here
uncommented?


graphics_toolkit ("gnuplot") %Until the later bug is fixed
graphics_toolkit ("qt") %this one has bugs and does not work properly


One thing you can do to isolate the plotting from your script is to save the
workspace variables that you are plotting. For example it looks like Figure 2
is shown when Octave stops responding. You could try inserting


save foo.txt InMat2


into your script. Now quit Octave, start a new session, and try


load foo.txt;
subplot (2, 1, 1);
surf (InMat2(:, :, 1));


Does this crash? If not, keep going. If it does, what about a smaller subset
of InMat2? Try to narrow down what is the minimal set of data that you need to
demonstrate the error.
