I'm having some issues with the new version of Octave in the repository. If I run it normally and try to plot, I get errors saying "insufficient GL support". Is there another package I would need?
As a workaround, I tried switching the graphics toolkit to gnuplot with the following commands:
register_graphics_toolkit ("gnuplot")
graphics_toolkit ("gnuplot")
Unfortunately, I get an error from the second command. It says "error: __init_gnuplot__: the gnuplot program is not available, see 'gnuplot_binary'". This doesn't make sense because I have gnuplot installed. Any ideas?
