Hello,
I’m trying to create a histogram which draws the tick marks on the negative side of the Y axis. I’m doing this via:
h1->GetYaxis()->SetTicks("-");
This works for the X-axis, but it puts the labels up into the data. This is not ideal behavior. The Y-axis doesn’t respond at all. I’m using root 5.18/5.19.
I’ve attached a small macro that reproduces the behavior as well as a png of it.
see this example. The simplest thing to do when you have this kind of problem is to use the graphics editor (see canvas “view” menu) , change the axis options using the GUI
and generate the canvas.C file from the canvas “File” menu.

void tic() {
TH1F *h = new TH1F("h","ticks & ticks",100,-3,3);
h->FillRandom("gaus");
h->GetXaxis()->SetLabelOffset(0.026);
h->GetXaxis()->SetTickLength(-0.03);
h->GetYaxis()->SetLabelOffset(0.018);
h->GetYaxis()->SetTickLength(-0.02);
h->Draw("");
}
Thanks so much, this works perfect! I’ll keep this in mind next time I’m designing a histogram!
