Humm. Even if you forget Device, Decomposed=0 you can usually
get *black*, for goodness sake. :-)

Something is *seriously* wrong with your IDL! You aren't
trying to set a system variable and have the same keyword
set on the Shade_Surf command, are you?

I believe it. :-)

Here is how I would do it. This works on the display
AND in PostScript. You can get the LoadData program
from my web page, or supply your own 2D data set.
data = LoadData(2)
LoadCT, 0 ; Start at the beginning.
LoadCT, 5, NColors=254, Bottom=1 ; Load colors for surface.
Device, Decomposed=0 ; So you can see some colors.
Set_Shading, Values=[1,254] ; Shading values correspond to colors.
Shade_Surf, data, Color=0, Background=255, Font=1, Charsize=3.0
Set_Shading, Values=[0,255] ; Set shading values to default.
Cheers,
David
