This may look like the obvious answer, but I don't think it is what is
best here.
I guess P�l wants to see bar graphs of category frequencies or percents
for one-, two- or three-way tables.
You can get useful results with a trick
gen frequency = 1
graph bar (sum) frequency, over(frog) over(toad)
once we recall that counting is adding 1s as many times as is needed.
But it is a small pain to extend this even to simple percent
calculations. So, as a convenience, there are various user-written
programs, of which -catplot-, -tabplot- and -spineplot- spring to mind.
-search- using these program names for program locations and
documentation, including various pieces in the Stata Journal from 2004
and 2008.
