I'm trying to plot a two-column data file in root. I've read it into root as an ntuple. Now it seems that when I directly plot the ntuple (i.e. using "ntuple_name->Draw()") that root creates a scatter plot of the data by making it a 2D histogram, and plotting that. I'm trying to do a fit to this data (root's nice fitting routines are why I'm doing this in the first place), and I can't use any of the predefined functions since they are all 1D functions (and therefore only capable of fitting 1D histograms). I am also not certain that defining my own function of two variables is the right way to do this since I'm not really trying to fit a surface. Can anyone help with this? I can't be the only one who has tried to do this... Thanks, Vic Gehman
