Different scaling in each bin

ROOT
1

I know that histogram can be scaled by doing:
hist->Scale(factor);
Is there anyway I can apply a different scaling factor to each bin ?

                  -thanks debdatta.

Loop on each bin calling
double cont = h->GetBinContent(bin);
h->SetBinContent(cont*scale_factor_bin);
or
h->Multiply(h2)
