Thanks for the reply, Is there anyway I could con a small example? I've read up about the 2D histograms, and I think I know how to create one with this TH2(name,title,nbinsx,xlow,xup,nbinsy,ylow,yup) but I'm not sure about how to place points on the graph to make it look like a line plot. The tutorials are all fancier than I need.
