It is NOT possible using the direct graphics routine CONTOUR.
You would have a great deal more control if you were to use
the object graphics routine IDLgrCONTOUR. But, there would
be a significantly longer learning curve. You might be able
to use XContour from my web page as a place to jump-start
the process:

XContour is *very* old. If you manage to improve it, I'd like
to hear about it. :-)
Cheers,
David
