FillRandom() at a new mean?

Is it possible to use FillRandom() for a mean other than zero?

I assume your question about TH1::FillRandom. It requires you to pass a function name (like gaus).
You can do, for example for a gaussian:

TF1 * gaus = (TF1*) gROOT->GetFunction("gaus");
gaus->SetParameter("Mean",value);
h1->FillRandom("gaus");

Exactly what I was looking for, thanks!
