histogram label position

[filippo dare]

Hi everybody, a stupide question here, but I am not able to find sollutions. I am running the following code. I would ask you if there is any way to center the xlabel on the bar. That because when I change bar size the xlabel does not move.

You need (mostly) the discrete option.

Consider this as a better start:

twoway histogram high, discrete percent by(grade, row(1)) barwidth(0.2) graphregion(color(white)) xlabel(0 "non high" 1 "high")

That said, a binary outcome and a binary predictor boils down to two means, as the % scoring 1 = 100 MINUS % scoring 0. Do you need a graph at all?
