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
