Well thanks, I found it useful. The esrg library wasn't installed on
my system, so I didn't know the wonders of TVIM before.

But. I'm having trouble with printing color postscript files: on
screen it looks perfect, but on my ps-file the borders of the graph
are missing (ie presumably white).

So, what do I do:

I startup IDL and say 'window,/free,/pixmap,colors=256'
After that, I have to load the colormap I want to use, and I have to
use xloadct for that since I want my particular colormap (no 5, STD
GAMMA-II) reversed.
I create my postscript plot:

set_plot,'ps'
DEVICE,file='colplot.cps',/color, bits=8

End I end up with a graph with white borders (probably color index 255
is set to white somewhere?) Using 'toggle' doesn't make any
difference.

So, can somebody tell me what I did wrong, and how I can do it right?

Thanks in advance.
