I'm trying to show a data array as a surface. The help

prepare the data and secondly can I show more than one
surface on a single chart?

See www.tushar-mehta.com, 3-D surface charts for answers to your first
question.

The second question (multiple surfaces) is pretty tough if the surfaces
overlap. I'm not sure how to visualize that...
