Hello everyone I have some experimental data and simulated data of some beta decay. I want to find out a method to scale down the experimental data and stretch or shrink it so it will fit the simulated data, and getting the parameters that root used for this fit, something like: Ah(ax+b), where “…

Can we shift histogram for several channels? ROOT

I’m not sure if this is fully kosher, but suit yourself : #include "TAxis.h" #include "TH1.h" #include "TArrayD.h" Double_t ScaleX(Double_t x) { Double_t v; v = 10 * x + 100; // "linear scaling" function example return v; } Double_t ScaleY(Double_t y) { Double_t v; v = 20 * y + 200; // "linear scaling" function example return v; } Double_t ScaleZ(Double_t z) { Double_t v; v = 30 * z + 300; // "linear scaling" function example return v; } void ScaleAxis(TAxis *a, Double_t (…
