Hello, I need to get data points, or "y values", from a histogram I have. For example, if I know the horizontal, or x, value of a histogram, what command do I use to get the y value out? More specifically, say that my histogram corresponds exactly to the function y = x^2, then if I wanted to know the function value at, say x = 4, then the program would give me 16. I have tried h1->GetBinContents(x); but this hasn't seemed to work. It seems like it should be easy enough to do - but I haven't found the right command yet. Any help would be greatly appreciated. Thank you. mjd
