Hello,
I am beginner in ROOT. I need to write simple macro. I am trying set title and name in Canvas but it is not correct.
Can anyone tell me how to correctly add a title and name in Canvas?
Thank you and best regards
void macros1() {
TFile f("Pion1GeV.root");
TTree * evt = (TTree*)f.Get("evt");
TCanvas c1("Pion E=1GeV", "Pion E=1GeV; z; x:z", 1600, 1000);
evt->Draw("x:z");
c1.SetTitle("Pion, E=1GeV");//doesn't work
c1.SetName("Pion, E=1GeV");//doesn't work
f.Close();
c1.SaveAs("Pion1GeV.png");
}
