Hi Marc:

Here's an example:
**************!
sysuse auto, clear
graph hbox mpg, over(foreign)

levelsof for, loc(ll)
foreach v in `ll' {
qui su for if for==`v', d
loc nn = `r(N)'
lab	def origin `v' `"`:lab origin `v'' (n = `nn')"', modify
}
lab li
qui su for, d
graph hbox mpg, over(foreign) note(total n = `r(N)')
**************!
Also, there are more detailed examples/tips on my site:  http://goo.gl/nYAMl
