THStack with RDataFrame

[eballabe]

Hi @eguiraud,
I just solved the issue (nothing to do with RDataFrame). I just changed the last line:

hs.Draw("HIST")

as I read here:

THStack not filling histograms with color

Dear all, I am encountering a very peculiar esthetic issue: I have 8 histograms stacked with a THStack and drawn, each filled with its own color: histo1->SetLineColor(1); histo1->SetFillColor(1); … I then stack them, and draw them and everything works fine. Then I realized I actually need to weight those histograms when filling them: histo1->Fill(variable, weight1); … And now, with weighted histos, the stack only draws the histograms line and not the “interior”. How can I solve this? Mo…

Thanks for the reply!
