How to make the Statistics box appear when plotting a THStack (Pyroot)

I’ve been plotting THStacks using:

canvas107 = ROOT.TCanvas("c_mc_truth_delta_r_lower", "", 800, 800)
S["mc_truth_delta_r_lower"].Draw("HIST S SAME")
canvas107.Draw()
canvasas['107'] = canvas107

but I can’t get the stats box to appear. Problem is, when I plot the elements of the stack separately, it messes up the plot title, axes labels, and presents the histograms in a way I don’t want. Is it possible to preserve the stack and get the stats box?

Hi @Diracula ,

can you provide a minimal self-contained reproducer for your problem? I’m sure then @couet will be able to help.

Some ideas:

have this example:

{
  THStack *hs = new THStack("hs", "test");
  TH1I *h1 = new TH1I("h1","h1", 3, 1, 4);
  TH1I *h2 = new TH1I("h2","h2", 3, 1, 4);

  h1->Fill(2);
  h2->Fill(2);

  h1->Draw();   
  gPad->Update();
  TPaveStats *ps1 = (TPaveStats*)h1->GetListOfFunctions()->FindObject("stats");
  ps1->SetX1NDC(0.1);
  ps1->SetX2NDC(0.3);
  h2->Draw();   
  gPad->Update();

  h1->SetFillColor(kRed);
  h1->SetMarkerStyle(21);
  h1->SetMarkerColor(kRed);

  h2->SetFillColor(kBlue);
  h2->SetMarkerStyle(21);
  h2->SetMarkerColor(kBlue);

  hs->Add(h1);
  hs->Add(h2);

  hs->Draw();
}
