Hi, This features has been added to the CVS repository. Enjoy, Philippe. -----Original Message----- From: owner-roottalk@pcroot.cern.ch [mailto:owner-roottalk@pcroot.cern.ch]On Behalf Of Gernot Maier Sent: Wednesday, August 01, 2001 11:11 AM To: roottalk Subject: [ROOT] Filling a TProfile2D Hej Rooters, maybe a very simple question, but I don't manage to fill a TProfile2D from Tree. I did: myTree->Draw("var1:var2:var3","somecuts","prof"); The resulting histogram is empty. As I understood the Usersguide (v.3.1a) on page 51 it should work like this. The definition of a TProfile2D histo and filling it then with myTree->Draw("var1:var2:var3>>hisProf2D","somecuts","prof"); gives a seg fault while drawing the histogram. I'm using Root 3.01/06 on alpha OSF and SuSe Linux. thanks in advance Gernot ----- Gernot Maier KASCADE Collaboration Institut fuer Kernphysik Tel. +49 (0) 7247 82-4174 Forschungszentrum Karlsruhe maier@ik1.fzk.de
