Hi, I tried to divide canvas into 2 by 2. When I clike canvas window to get the canvas menu and clike divide in canvas menu(I mean using GUI) it works. However, when I type the command, "c1->GetPadDivision(2,2)" it does not work. When I execute the following commands, it draws histogram on original canvas c1 instead of on the 1st pad in canvas. root [0] TFile file("../ntuple.root"); root [1] c1 = new TCanvas("s1","Histogram",700,500) (class TCanvas*)0x0 root [2] c1->cd(1); root [3] c1->GetPadDivision(2,2); root [4] c1->cd(1); root [5] si_adc.Draw("a0","iny==8 && inx==10"); Could you help me? --- Thanks, Jayoung
