Hello,
Apologies for reposting my question from yesterday (save image as
color-mapped 8-bit rather than true-color). I am hoping this
reposting clarifies what I am trying to accomplish.
The attachment is a simple script that creates a 2D array of unsigned,
8-bit integers and uses

Hello,
The attached script shows my (failed) attempt to define a custom color
map from a set of RGB values (taken from an IDL palette).
My approach is presumably completely wrong, but I have not found
information or examples on how to do this.
Could someone point in the right direction?
not understand how to use that example to replicate an
IDL color map.
The requirement is for me to exactly duplicate the IDL color map
(actually several IDL color maps) listed in my script.

Hmm,
vmin and vmax should work.

OK, upon a more careful review of the code, I made a simple(-minded)
error. Specifying vmin and vmax do work (as everyone already knew).
Thanks to Jae-Joon and Eric for their quick replies. and valuable

Hello,
Maybe my googling skills are deficient, but I wasn't able to find any
information on how to define my own colormap.
Can someone give me a pointer, or a basic example how to create a simple
map that e.g. maps -1 to Red, 0 to White, and 1 to Blue?
Thanks,

Hello.
I would like to know, please, how you can add graphics on a same plot.
eg :
superpose sine and cosine graphs on the same plot.
Thank you very much.
