In other words, one of the histograms would be semi-transparent.

    sysuse auto, clear

twoway histogram mpg if foreign, width(2) start(12) blcolor(red) bfcolor(none) fraction || histogram mpg if !foreign, width(2) start(10) barw(1.8) bfcolor(none) blcolor(blue) fraction ytitle(Proportions) legend(order(1 "Foreign" 2 "Domestic") col(1) pos(1) ring(0))
