I have a series of stereographic SABER temperature plots (so 2D) on
different pressure surfaces and want to present them in a way such
that the vertical relationships between two different surfaces can
been seen. Up until now, I have been generating the pressure surfaces
(or as I call them slices) in IDL and then manipulating them
individually in Adobe Illustrator by using some shear commands that
make the slices appear that they are hovering over each other (like a
deck of cards with an inch of air between each card). This is time
consuming (especially for many such plots, not to mention being a
rather inelegant solution) and I have been trying to recreate the 3D
stacked map projections using IDL. I have looked on several forums
and on google for potential solutions in map projections and 3D
plotting, but seem unable to find what I need (I don't even know if
what I'm doing has a proper name). Do you have any ideas or solutions
for presenting data in this way?
Any help/ideas are greatly appreciated.

I was just trying to get a better picture of what you are looking for.
Then use a series of calls to icontour, similar to what I guessed
above, each one with a different zvalue. The amount to separate (the
distance in zvalue) will depend on their dimensions and the angle you
want to see the stack, so if you will have to experiment with it.
