I am using the following Macro to create a histogram “Gamma”, whenever I reload the macro in root I get the following message:
Warning in TH1::Build: Replacing existing histogram: Gamma (Potential memory leak).
I thought adding the Gamma->Reset() should take care of that but it didn’t.
the macro is :
{
TCanvas *2d_v1_Gamma = new TCanvas(“2d_v1_Gamma”,"(nOut/nTop) Vs (nb2/cxPE) for Gamma");
Gamma->Reset(); // This will reset the Gamma histogram so you wont
//keep getting the message "Potential Memory Leak"
TH2F *Gamma = new TH2F(“Gamma”,“Gamma”,40,0,17.5,40,0,0.54);
gStyle->SetOptStat(“kFALSE”);
t1->Draw("(nOut/nTop):(nb2/cxPE)>>Gamma",“sqrt(xcorexcore+ycoreycore)*(primary==1 && nTop>55 && nFit>80)”,“COLZ”);
Gamma->GetXaxis()->SetTitle("(nb2/cxPE)");
Gamma->GetYaxis()->SetTitle("(nOut/nTop)");
Gamma->Draw(“COLZ”);
TPaveText *pt = new TPaveText(0.7,0.9,0.9,0.995,“blNDC”);
pt->SetName(“Kharra”);
pt->SetBorderSize(2);
pt->SetFillColor(19);
TText *text = pt->AddText(“Multiplicity Trigger of 50 PMTs”);
pt->Draw();
}
Any ideas
