Hi,
I am trying to set the axis range on a histogram with the following lines:
TFile* f = new TFile("mode-04-plots.root","READ");
TH1F* h1 = (TH1F*)f->Get("channel_0");
can->cd(4); //A divided TCanvas
h1->GetXaxis->SetRange(((h1->GetMaximumBin())-100),
((h1->GetMaximumBin())-400));
h1->DrawCopy();
These lines produce the error message:
Error: Can't call
TH1F::GetXaxis->SetRange(((h1->GetMaximumBin())-100),
((h1->GetMaximumBin())-400))
in current scope FILE:mode-04-plots.C LINE:54
Possible candidates are...
filename line:size busy function type and name (in TH1F)
filename line:size busy function type and name (in TH1)
filename line:size busy function type and name (in TNamed)
filename line:size busy function type and name (in TObject)
filename line:size busy function type and name (in TAttLine)
filename line:size busy function type and name (in TAttFill)
filename line:size busy function type and name (in TAttMarker)
filename line:size busy function type and name (in TArrayF)
filename line:size busy function type and name (in TArray)
*** Interpreter error recovered ***
Could someone point out what I am doing wrong?
