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
