Online Help for "ISURFACE procedure" gives this:

Insert a contour onto the surface by clicking the Surface Contour button on
the toolbar, then clicking and dragging on the surface to position the
contour at the desired height.

But I found that I couldn't get any contours with:
iSurface, sin(xx)*sin(yy),xx,yy
... I had to just use:
iSurface, sin(xx)*sin(yy)

I think that if you look in Online Help:Using IDL iTools:Working with
Surfaces (or Contours) you will find more of what you are looking for.

Cheers,
