Dear all, A basic question, I am running on dec/alpha/4, and using root version 2.24/02. I have create a tree of which one branch is a TH1F object with the following procedure : main(int argc, char **argv) { TH1F *myhisto; TTree *CELL; // Create a ROOT TTree CELL = new TTree("T","My TTree"); CELL->Branch("myhisto","TH1F",&myhisto,128000,0); ... filling myhisto ... // here i fill the Tree CELL->Fill(); ... write CELL in a root file ... return 0; } I mean this is the right way to process, but how can I access to myhisto (draw it for example)? Thanks, Lionel Neukermans
