I did not implement a TH3::SetBinContent(binx,biny,binz).
Use TH1::SetBinContent(bin) where
Int_t bin = hist->GetBin(binx,biny) for a TH2 object
Int_t bin = hist->GetBin(binx,biny,binz) for a TH3 object
Int_t bin = hist->GetBin(binx) for a TH1 object if you like!

Once you have bin, you can use all the Get/Set bin methods, eg
hist3->GetBinContent(bin)
