I've been working a lot on improving the OpenGL plotting, but it's true that a lot of the fixes are still ond the development branch and won't be released until 4.2.

Thanks for the hint, Rik. I also try to slowly move over to fltk. But my current installation still has gnuplot as default, since the fltk plots still have some esthetic drawbacks (linewidth, fontsize), which I heard will be fixed.

So currently I'll report gnuplot errors in octave along the way, when I hit them. But I won't get upset if noone makes it his priority to fix them.

I notice you have filed several bugs against plotting with gnuplot. Octave has been moving away from gnuplot steadily since the 3.6.X series. Partly because the interface is slow as it has to be run over pipes. And partly because we don't have as much control over the appearance as we do with the much more tightly integrated OpenGL plot engines in FLTK or Qt. It's fine to report these, but I know the core developers aren't working on further gnuplot integration.

Here is how to reproduce the behavior:

Instead of some nice 3d pie charts I only get an error message:

This only happens with gnuplot. Fltk plots seem to be fine.

This happened with the octave release 3.8.1 as well as the current pre-release 3.8.2-rc1 under Ubuntu Linux. I don't know if it happens under Windows as well.

I use Gnuplot 4.6.1-1 (package 4.6.1-1~precise1 from the standard repository of Ubuntu 12.04).
