TH1::GetBinLowEdge is a shortcut for h->GetXaxis()->GetBinLowEdge To be general, I would strongly recommend to always get the axis info (1-d,2-d,3-d, why-not multi-d}) via TAxis *xaxis = h->GetXaxis(); xlow = xaxis->GetBinLowEdge(bin); TAxis *yaxis = h->GetYaxis(); ylow = yaxis->GetBinLowEdge(); etc. Rene Brun
