Thanks

TH1F - read and made histogram

That’s maybe something for @couet In the meantime, you could try: gStyle->SetOptStat(); // just a precaution ((TH1*)(hs->GetStack()->Last()))->Draw("HIST L"); // the sum hs->Draw("SAME HIST L"); or: gStyle->SetOptStat(); // just a precaution TH1 *hl = ((TH1*)(hs->GetStack()->Last())); // the sum hl->SetNameTitle("MyName", "my title;my X axis;my Y axis"); hl->Draw("HIST L"); hs->Draw("SAME HIST L"); where, instead of: hl->SetNameTitle("MyName", "my title;my X axis;my Y axis"); you could us…

The “final histogram” does not exist when you draw a stack of histograms. To get such information you will need to add all the histograms in a single one. Then you will be able to get the stats on the total.

Thanks couet! Yes this was my doubt. So after getting the stat information from the added histogram, these(ex:Entries) can be put as text on the stacked histogram canvas.

Use the getters to get Entries etc … and draw them as text using something like

auto Text_Entries = new TText( xpos, ypos, Form("Entries = %g\n", hsum->GetEntries());
Text_Entries->Draw();

And why don’t you simply use my example?

Hi Wile,

Thanks! Its working. But there is another outer line coming on the stacked plot. How to avoid this as attached

here?

Oh Sorry! Just removed the L option in drawing. Then only the histograms.

Thanks!
