Hi Xavier,
One can superimpose a lego and a surface plot in the following case:
  - number of bins and range are identical
  - min and max the same.

In your case, just do:

    hd->SetMaximum(mymax);
    hd->SetMinimum(mymin);  mymin = 0
    hf->SetMaximum(mymin);
    hf->SetMinimum(mymin);
    hd->Draw("LEGO");
    hf->SetLineColor(2);
    hf->Draw("SURFSAME");
