Dear all,
I use root 2.25/02.
I can use histo1->GetXaxis()->SetTitle("X-Axis") in histogram.
But when I employ this to TGraphErrors (gr->GetXaxis()->SetTitle("X-Axis")),
I fail. There is a segmentation error message.
Why couldn't I use it in TGraphErrors ?
Thanks for your help !
Sincerely,
Chia Ming
