Thanks many people for contributing their ideas on the multi-surface
plot problem. Inspired by Dr. L. Kramer, I tried the following way which
works pretty well for me:
IDL> surface, Z1, ZRANGE=[100,300], /nodata, /save ;setup coordinates
IDL> surface, Z1, ZRANGE=[100,300], /T3D, xstyle=4, ystyle=4, zstyle=4, /noerase
IDL> surface, Z2, ZRANGE=[100,300], /T3D, xstyle=4, ystyle=4, zstyle=4, /noerase
... ... (repeat this on Z3 and Z4)
It's even better if you use different color for each surface.
Because many people expressed their interest in this problem, I think
it might be good to post this solution.
Finally, Thanks, Leonard. Great idea!
