No, not in official data.
Often there are two dimension reductions that serve just as well. The -
vibl- package is one example of useful two dimensional plots, where a
3 dimensional plot is a natural choice, (http://www.ats.ucla.edu/stat/Stata/seminars/stata_vibl/vibl.pdf
).
But anyway, you have a free alternative in several R packages, such as:

Commercial packages like JMP 7 or 8 do this kind of plot well. Also
Data Desk 7, but development has stopped on this package.

Can stata make a three-dimensional graph? I want to show how two
variables (one dichotomous and one continuous) change over time with
respect to a dependent variable. I can envision something three-
dimensional getting the point across but haven't found anything in
the manuals to lead me in that direction. Is it possible?
Thanks,
Jennifer
