Hi rooters, I'm working with some fits of 2-dimensional histograms with TF2's. But, since people have a hard time seeing fits of 2-d histograms, I'd like to present these in 1-D slices. I'm finding that, while it's easy to get the slices, it is hard to get the 1-D function representing the fit values at the midpoint of the bin. In other words, what I would like is a way, given a TF2, to create something that looks like a TF1 from it, binding one or the other coordinates of the TF2 to a specific value. I'm not sure exactly how this would look, but something like: TF1 * newf = TF2.BindX(33); TF1 * newg = TF2.BindY(13.2); would work. I don't think there's anything like this now, but if there is, please let me know how to do it. ;) If not, I think it would be an extremely valuable addition to ROOT. George Heintzelman gah@bnl.gov
