Hi,
The best is to use a THStack like in $ROOTSYS/tutotials/hist/hstack.C

Subject: [ROOT] 3D histos together
Dear rooters,
sorry if this question was already raised (in fact I remember somewhere it was asked but do not find the answer). Is there a way to display more than one 3D histos in one pad (not superimposed)? I created a trivial example of what would like to have but not in 4 pads. To explain my need. I have 4 plates of silicon pad and I want to see a particle passing throw all of them showing energy realize in each pad. The z axis should be repeated several times: 0-Emax, 0-Emax, etc
Please find below a bad example of what I want. Thanks, Dmitry
void test_3d() {
TH2F *h1 = new TH2F("h1","",10,-2,2,10,-2,2); TH2F *h2 = new TH2F("h2","",10,-2,2,10,-2,2); TH2F *h3 = new TH2F("h4","",10,-2,2,10,-2,2); TH2F *h4 = new TH2F("h3","",10,-2,2,10,-2,2);
// fill the histos
h1->SetBinContent(3,4,10); h2->SetBinContent(4,5,10); h3->SetBinContent(5,6,10); h4->SetBinContent(6,7,10);
TCanvas *c = new TCanvas("c","",400,1600);
c->Divide(1,4);
c->cd(1);
h1->Draw("lego");h1->SetStats(0);
c->cd(2);
h2->Draw("lego");h2->SetStats(0);
c->cd(3);
h3->Draw("lego");h3->SetStats(0);
c->cd(4);
h4->Draw("lego");h4->SetStats(0);
c->cd();
// or like this
TCanvas *c2 = new TCanvas("c2","",400,1600);
// fill the histos
h1->Draw("lego"); h2->Draw("lego same"); h3->Draw("lego same"); h4->Draw("lego same");
