Gaus generator for histograms

[Akash116]

How do you customize the mean and variance for a gauss function in hist.FillRandom(“gaus”,n_fill)?
my search led me to TRandom but I guess that Gaus is simply a num generator.___

Fill the histogram with mean=1 and sigma=2

import ROOT f = ROOT.gROOT.GetFunction("gaus") f.SetParameters(1.0, 1.0, 2.0) # Constant, Mean, Sigma h1 = ROOT.TH1F("h1", "", 100, -10.0, 10.0) h1.FillRandom("gaus", 10000) h1.Draw() { TF1 *f = ((TF1*)(gROOT->GetFunction("gaus"))); f->SetParameters(1.0, 1.0, 2.0); // Constant, Mean, Sigma TH1F *h1 = new TH1F("h1", "", 100, -10.0, 10.0); h1->FillRandom("gaus", 10000); h1->Draw(); }
