{
  TH1F *h = new TH1F("h", "h;X;Y", 100, -5., 5.);
  h->FillRandom("gaus");
  h->Draw("HIST");
  TH1 *hh = (TH1*)h->Clone();
  // hh->SetLineWidth(0);
  hh->SetLineColor(kGreen);
  hh->SetFillColor(kGreen);
  hh->GetXaxis()->SetRangeUser(1., 2.);
  hh->Draw("SAME HIST");
  h->Draw("SAME HIST");
  h->Draw("SAME AXIS"); // ... or ... gPad->RedrawAxis();
}

Try, e.g.: hh->SetFillStyle(3003);
