How to iterate over tree with dynamically generated branches

[thart]

Hi Jean-François,

thanks for the suggestions – I will give it a try.

Actually, I tried the >> redirection into a histogram but failed so far to get it working in Python as in cint

Redirect branch into histogram?

Hi, you could do the following: import ROOT canvas = ROOT.TCanvas("canvas","Canvas Title") canvas.cd() rootTree.Draw("myBranch>>histo(100.,0.,30.)","anotherBranch==1") histo=ROOT.gROOT.FindObject("histo") histo.Draw() canvas.Update() canvas.Print("foo.pdf" )
