Re: st: percentage label with legend

"somewhere while googling" is a fairly vague reference, but the
apparent contradiction can easily be resolved.  -graph, pie- was the
syntax before Stata 8; in Stata 8 upwards the commands

webuse auto
tabulate foreign, generate(f)
graph7 f1 f2, pie

will automatically produce labels with percents explicit.

I wrote a -pieplot- (SSC) which is a convenience wrapper for -graph,
pie- so that for example

pieplot foreign, percent

shows percents. However, it does not support what Tashi wants. In my
view legends are at best necessary evils, so I try to lose them, not
add more information to them.

As in previous threads, this is all a matter of taste, but what Tashi
is doing is in my view much better done using a bar or dot chart.
