Hi all,
I am having an issue regarding the axis. I run my macro and no axis is drawn , just the frame of the plot, what should I add?
{
TFile f1("run1/zcr_data_irr_e.root");
TH1 *ff_data_irr = (TH1*)f1.Get("ff1");
TFile f2("run1/zcr_data_irr_ttb_e.root");
TH1 *ff_data_irr_ttb = (TH1*)f2.Get("ff1");
TCanvas *c4 = new TCanvas("c4","c4");
ff_data_irr->SetMinimum(0);
ff_data_irr->SetMaximum(1.3);
ff_data_irr->SetMarkerStyle( kCircle);
ff_data_irr->SetMarkerColor(kRed);
ff_data_irr->SetLineColor(kRed);
ff_data_irr->Draw("AP");
ff_data_irr->GetYaxis()->SetLabelSize(0.05);
ff_data_irr_ttb->SetMarkerStyle(kFullCircle);
ff_data_irr_ttb->Draw("APSAME");
TLegend * legSyst = new TLegend(0.55,0.75,0.95,0.9);
legSyst->SetTextSize(0.04);
legSyst->SetNColumns(1);
legSyst->AddEntry(ff_data_irr, "data - irr","lp");
legSyst->AddEntry(ff_data_irr_ttb, "data -irr-ttbar","lp");
legSyst->Draw();
c4->Modified();
}
Thanks!
Cheers,
