How to get the y-range of a TH1F?

Hi,

I need to access the range of the y axis of a TH1F. GetXmax() seems to always return 1, regardless of the actual range.

TH1F h("h","h",100,0,100) h->Draw() h->Fill(0.5) h->Fill(0.5) h->Fill(0.5) h->Fill(0.5) h->Draw() // maximum is 4 something h->GetMaximum() // returns 4 h->GetYaxis()->GetXmax() // returns 1 h->GetYaxis()->SetRangeUser(0,5) h->Draw() // maximum is 5 h->GetYaxis()->GetXmax() // again returns 1

Thanks,
