Thanks for this. Your specific examples are very welcome.
Your graph can be produced directly by
. sysuse auto, clear
. catplot hbar foreign rep78, percent(foreign) asyvars
I personally would prefer this example from the help
for -tabplot- (SSC)
. tabplot for rep78, percent(foreign) showval(offset(0.05) format(%2.1f))
while there is always something like this:
. histogram rep78, discrete by(foreign) xla(1/5) percent barw(0.6)
