Hello ROOTers,
I want to fit the curve exponentially.
I tried this
TF1 *f1 =new TF1(“f1”,“expo(0)”,0,20);
g1->Fit(f1,“R”);
but not got what I really want?
What will be the correct code???
Thanks,
Summit

Your distribution is certainly not an exponential distribution. You better fit it with a “pol2” or “pol3”
