The reference here is to -surface- from SSC. Please remember to explain where user-written programs you refer come from; this is a very longstanding request on this list. -graph combine- is just doing precisely what it claims, juxtaposing graphs. All you can do with -graph combine- is put graphs side by side. There is absolutely no scope for it to do what you want. Nor is it surprising that there is no option controlling z-axes; Stata has no concept of a z-axis and any appearance to the contrary is just a programmer-produced illusion. What you want I think requires non-trivial Stata programming or recourse to other software. Good official support for 3-D graphics has been on many users' wishlists for some time, including mine. but as of now I don't see a way to do what you want in Stata. (Whether the graph could be drawn to work well is a separate issue.)
