Dear expert,
I want to plot histo, h1 and h2 on same canvas c1, but the code mentioned below Draw h1 and h3 on same canvas. Is there a way to draw h1 and h2 on same canvas without closing/deleting c1, also not defining any new canvas for h3. i.e I want h3 draw on default canvas… I also don’t want to change the ordering of drawing of histos.
void can()
{
TH1F *h1 = new TH1F("h1","par",540,0,540);
TH1F *h2 = new TH1F("h2","Ch",100,0,400);
TH1F *h3 = new TH1F("h3","Ch2",100,0,400);
TCanvas *c1 = new TCanvas("c1","param");
c1->Divide(2,1);
c1->cd(1);
h1->Draw();
c1->cd(2);
h2->Draw();
h3->Draw();
}
