I have string labels for bins that I would prefer over just seeing the numbers. A common problem with text on tick labels is poor spacing, however, TH2 can easily have labels on the y axis, so I imagine that drawing the axis’ text on y is doable for TH1 as well.
The way I’m hoping that ROOT supports is that everything is the same except I’d need a specifier to draw with x and y axes flipped while or before I call TH1::Draw. But if this isn’t the case, I’ll take any answer.
