Really ? What about your VRML display :-) To answer Tao in another way:
Did you get an error message like "dgl error (access): dgl server access denied..."
This would mean that the GSAS plot routine is trying to use the SGI graphics
language driver "openGL", which is really only useful for 3D plotting. Unless you
have a PC emulator that knows about openGL, you can't display openGL graphics
on your PC:-)
But for 2D line plots, you don't need openGL. There must be an option with
SGI-GSAS to use another type of graphics driver. You should choose that.
BTW, an excellent general purpose 2D and surface plotting library for both
Unix and PC's is Tim Pearson's 'pgplot' package. It will work on X-terminals too.
We have pgplot based Unix powder plotting applications (with Win95 style GUI's :-).
