I don't know a way to do this. A different kind
of answer, which possibly you don't want, is
to change to a different graph type, for it's the
stacking of small and large bars that is causing
the difficulty. For example, with the auto data, I can go
tabplot foreign mpg, percent(foreign)
bysort foreign rep78 : gen freq = _N
bysort foreign : gen base = _N
gen percent = round(100 * freq / base)
gen foreign2 = 1.95 - foreign
tabplot foreign rep78 , percent(foreign) scheme(lean1) plot(scatter foreign2
rep78, ms(none) mlabel(percent) mlabpos(0))
The 1.95 here is not general. A more general rule
would be #categories - 0.05. (In -foreign-, 2 categories.)
I guess your underlying problem has the structure of
vgrup X v2
and the -vgrup?- are just a set of dummies.
So your recipe could be something like this.
-tabplot- is on SSC. There is a discussion in Stata Journal
