Details:
Ubuntu 14.10 with gnome-shell
To me it only happens if the plot contains a lot of data, in my case 93
thousand samples extracted from wav file using wavread. The plot works just
fine, i was able to plot this data against sample number without issues.
But when I try to "Save as" .png or .jpg, the plot freezes and gs process
appears, hogging ~ 50% of CPU time. Ctrl+C in Octave window restores the plot,
but the save fails.
I am able to save as pdf without issues.
I had some warnings before about epstool and fig2dev missing and before I
installed (using synaptic) epstool, transfig, fig2ps (and it's automatically
suggested dependencies) I had errors "__save_as__ undefined near line (..)"
After I installed those packages I was able to save some other plots.
I believe it is related to size of data being plotted
On my system
t = 1:1:500000;
plot(t,t)
Is enough to get the hanging gs process. No errors appear in Octave console. I
do not know where I could look for more information/logs/errors about the
issue
