hi ;) i'm a newbie of this very interesting language.
I use the 5.0 version of IDL for Windows95, and i have this problem.

I need to make a graph which contains more different plots inside. I
have used the commands plot and oplot with the keywords Color but i have
no what i want. The result is indeed the graph i need but every line is
showed in a grey level rather then in a color way.
Here is a little prg i have written for testing the graphic capabilities
of IDL.

Could someone help and show me where i make mistakes ?

thanks lot

Vince
