I like -stripplot- by Nick Cox for these kinds of graphs.
you can download it by typing in stata -ssc install stripplot-.
There are many examples in the help file to play with.
Note that the help file assumes that you recognize the
variable names as comming from the auto.dta dataset that
comes with Stata, and which you can load by typing in
Stata -sysuse auto-.
Hope this helps,
Maarten
