Hi I am having trouble with overlapping 3 Histograms in one drawing. Do you have any documentation or could you provide input on my code:
void Distribution(){
TRandom3 a;
TH1D *h = new TH1D(“h”, “h”, 100, 500, 600);
for(int i = 0; i<100000; i++){
double val1 = a.Gaus(550, 16);
//double val2 = a.Gaus(550, 8);
//double total = val1+val2;
h->Fill(val1);
}
TH1D *f = new TH1D(“f”, “f”, 100, 500, 600);
for(int i = 0; i<100000; i++){
//double val1 = a.Gaus(550, 16);
double val2 = a.Gaus(550, 8);
//double total = val1+val2;
h->Fill(val2);
}
TH1D *d = new TH1D(“d”, “d”, 100, 500, 600);
for(int i = 0; i<100000; i++){
double val1 = a.Gaus(550, 16);
double val2 = a.Gaus(550, 8);
double total = val1+val2;
h->Fill(total);
}
TH1D *c = new TH1D(“c”, “Overlap”, 100, 500, 600);
c->Add(h, f, d);
c->Draw();
}
