I'll have to look to see what the gray color is about,
but this is the wrong way to call these commands. The
correct way is like this:

> IDL> cgplot, indgen(10),color="Dodger Blue", /window
> IDL> cgplot, indgen(10)+1, color="Hot Pink", /window, /over

I think when you pass Hot Pink through cgColor twice, the
value turns into a long integer, which gets interpreted
incorrectly. It's late here, so I'm not thinking as
clearly as I usually am. :-)

I'll look into it.

Cheers,

David
