Root histogram integral
Web1) define a function which should reproduce the background. 2) create a TF1 whose expression is Background + Gaussian. 3) fit the whole histogram with that TF1. 4) create two new TF1 objects containing the Background only and the. Gaussian only. 5) compute the integral of the Background TF1 in the peak. WebJan 13, 2016 · I am trying to create a histogram with variable bin width, but I believe that the constructor for TH1F states that the widths must be binwidth+1. Here are my lower bin bounds: 0.0, 0.4, 0.58, 0.90, 1.08, 1.50, 2.20. Is it possible for me to plot these variable bins? My input so far is: root [0] Float_t Lower [7]; root [1] Lower [0]=0.0;
