I have chained many TTrees together into a TChain. The chain now has about 4.3e9 entries. When I use the TChain::Draw like this:
TH1D *hnorm = new TH1D(“shift_norm”,“shift_norm”,nbins,xstart,xend);
I do not appear to be getting the full number of entries in the histogram, rather just 1e9 entries exactly. Is there a limit that I’m not aware of somewhere? I know about the ch->SetEstimate() but I thought that only applied to extracting the values from the chain in vector form.
