Hi,
I'm a beginner of using David's cgWindow. I'm wondering how to
display two images using two different color tables in a cgWindow?
I've tried a few things, but all failed.
A second quesiton I'm having is when I issue the command: "cgloadct,
13, /addcmd". It will pop up two resizable windows: one with black
background and one with white background.
My final question is regarding using postscript font in IDL 7.0. When
I generate a postscript file with ps font, the "multiple" sign cannot
be displayed correctly (displayed as a "dot"); e.g., 6x10^5 will be
displayed as 6*10^5. I have tried this on various computers with both
Win and Mac. All give the same results.
I'm wondering whether someone can help me with these IDL questions.
Many thanks in advance.
Bill

Whoops! The variable t should be this, of course:
t = ['6x10!A-9!x', '7x10!A-4!x']
Cheers,
David
