Hello all,
Since I got such a great response to my last post I thought I'd try one
more time. Thanks to JD I got the code running but now the
behaviour on Windows and Linux is different. On the Linux side my plot
window comes up with a white background, on the Windows side a black one.
Same code and version of IDL 5.3. Since I need the white BG I tried
!P.BACKGROUND = 255 on windows but no change.

To get IDL color maps to work under Linux
I have to have

in my IDL_STARTUP file
try that
