Hello,
how can I superimpose the histograms h1 and h2 in the following macro? Moreover, is this the correct way to use cuts? In fact, when I try to plot only one histogram I get an error message related to TCut.
Thank you,
Mark
void macro(){
TCut c1 “a==b”;
TCut c2 “d>e”;
TChain ch(“tree”);
ch.Add(“myfile1.root”);
ch.Add(“myfile2.root”);
TCanvas *C = new TCanvas();
TH1F *h1 = new TH1F(“h1”,“h1”, nbins, x1, x2);
TH1F *h2 = new TH1F(“h2”, “h2”, nbins, x1, x2);
ch.Draw(“Y>>h1”, c1 && c2);
ch.Draw(“X>>h2”, c1 && c2);
C->SaveAs(“myplot.pdf”);
}
