How to do a special histogram like this in Stata?

[smith Jason]

Hello, I saw a histogram by group like below.
I want to use the classical Stata data auto.dta to mimic it. (categorical variables-rep78, foreign; continuous-any variable in the dataset except for make and these two variables).
Can someone help me in Stata code?

I see two variables there. not three.

. sysuse auto, clear
(1978 automobile data)

. graph bar (percent), over(rep78) by(foreign) blabel(total, format(%1.0f))
