Hi everybody,
I have a root file which has 8 histograms. The aim is to draw all of them in one histogram. Out of these 8 histograms, I want to fit 6 of them with "gaus". But when I use the following script, it just draws the last histogram and fits it with "gaus". What am I missing here.
After reading all of them from the root file I am saying :
c1->SetBorderMode(1);
c1->SetFillColor(kWhite);
gStyle->SetOptFit(0);
gStyle->SetOptStat("");
c1->SetLogy(); h1->SetMaximum(500); h1->SetMinimum(0); h1->SetLineColor(2); h1->SetLineWidth(2); h1->GetXaxis()->SetRange(0,150); h1->Draw(); h2->SetLineColor(4); h2->SetLineWidth(2); h2->Draw("same"); h3->Fit("gaus"); h3->SetMarkerColor(8); h3->SetMarkerStyle(22); h3->SetMarkerSize(0.6); h3->Draw("pSame"); h4->SetMarkerColor(6); h4->SetMarkerStyle(29); h4->SetMarkerSize(0.6); h4->Fit("gaus"); h4->Draw("pSame"); h5->SetMarkerColor(50); h5->SetMarkerStyle(28); h5->SetMarkerSize(0.6); h5->Fit("gaus"); h5->Draw("pSame"); h6->SetMarkerColor(1); h6->SetMarkerStyle(30); h6->SetMarkerSize(0.6); h6->Fit("gaus"); h6->Draw("pSame"); h7->SetMarkerColor(3); h7->SetMarkerStyle(23); h7->SetMarkerSize(0.6); h7->Fit("gaus"); h7->Draw("pSame"); h8->SetMarkerColor(3); h8->SetMarkerStyle(23); h8->SetMarkerSize(0.6); h8->Fit("gaus"); h8->Draw("pSame");
Thanks very much for any help.
