David I think meant not in official Stata.
Jennifer's problem sounds, from another point of view, four-dimensional.
Even if it is, -mrunning- from SSC offers another alternative.

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.
