Hello,
I am trying to plot two graphs in two canvases but it is not working. Please help.
Thank you… 
//================ Temperature vs Multi ===========================================
TCanvas *Temp_vs_Multi = new TCanvas(“Temp_vs_Multi”,“Temp_vs_Multi”);
TGraphErrors *T_vs_Multi = new TGraphErrors(n,multi,Temp,multi_err,Temp_err);
T_vs_Multi->SetTitle(“Multiplicity dependence of Temerature in p+p collisions”);
T_vs_Multi->GetXaxis()->SetTitle(“Multiplicity”);
T_vs_Multi->GetYaxis()->SetTitle(“Temperature (GeV/k)”);
T_vs_Multi->SetMarkerStyle(20);
T_vs_Multi->SetMarkerColor(2);
Temp_vs_Multi->cd();
T_vs_Multi->Draw(“ALP”);
//=============== q vs Multi ======================================================
TCanvas *q_vs_M = new TCanvas(“Temp_vs_Multi”,“Temp_vs_Multi”);
TGraphErrors *q_vs_Multi = new TGraphErrors(n,multi,q,multi_err,q_err);
q_vs_Multi->SetTitle(“Multiplicity dependence of Non-extensive parameter q in p+p collisions”);
q_vs_Multi->GetXaxis()->SetTitle(“Multiplicity”);
q_vs_Multi->GetYaxis()->SetTitle(“q”);
q_vs_Multi->SetMarkerStyle(20);
q_vs_Multi->SetMarkerColor(4);
q_vs_M->cd();
q_vs_Multi->Draw(“ALP”);
