Hi Gernot,

I do not see a problem with TProfile2D::SetMaximum.
Could you run the following test ?
{
   TProfile2D *p2d = new TProfile2D("p2d","test max",40,-4,4,40,-4,4);
   for (Int_t i=0;i<10000;i++) {
      Double_t x = gRandom->Gaus(0,1);
      Double_t y = gRandom->Gaus(0,1);
      Double_t z = x*x+y*y;
      p2d->Fill(x,y,z);
   }
   p2d->SetMaximum(30);
   p2d->Draw("lego");
}

I am running with version 3 but there are no changes in this area
since version 2.25
