Hello!
I am plotting an angle from 0 to pi and would like the tick marks at fractions of pi ( i.e. pi/4, pi/2, etc ) and the label of these tick marks to actually be pi/4 etc and not the decimal equivalent.
I cannot find any documentation that shows how to tell an axis to do this. Surely there is a simple way.

The pi axis is not currently implemented (it will be). As a workaround see the example below
Rene
{
Double_t pi = TMath::Pi();
TH1F h("h","test",100,-pi,pi);
h.FillRandom("gaus",5000);
h.GetXaxis()->SetLabelOffset(99);
h.GetXaxis()->SetNdivisions(-4);
h.Draw();
TLatex l;
l.SetTextSize(0.04);
l.SetTextAlign(23);
double yl = -2;
l.DrawLatex(-pi,yl,"-#pi");
l.DrawLatex(-pi/2,yl,"-#frac{#pi}{2}");
l.DrawLatex(0,yl,"0");
l.DrawLatex(pi/2,yl,"#frac{#pi}{2}");
l.DrawLatex(pi,yl,"#pi");
}
Great! Thanks for the help.
