Re: problems with octave 8.2.0-1 and plotting

[Fabio Rossi <rossi.f@inwind.it>]

Hello Brian,
thanks for your suggestions, eventually I solved the problem with Achim's hint of using opengl software rendering because the graphics card is not supporting all opengl requirements.

I have followed this guide:

On the same machine, octave built for Windows executes correctly the same command. I have observed the same behaviour also on other Windows machines running Win7 or other graphic adapters.
