Re: [ROOT] How to get the histogramm after the TChain->Draw method.

Hi,
    Try 'TH1* htemp = (TH1*)gROOT->FindObject("htemp")' after calling
TChain->Draw.  The temporary histogram exists (with the name "htemp"); it's
just a hair more work to get a handle on it in compiled code than in CINT
because you have to attach it to an explicitly declared variable.
