Draw two TF1

[couet]

When two TF1 are drawn with option SAME the 2nd one might be partially drawn in case
there is a range defined on it. See:

https://root-forum.cern.ch/t/draw-two-tf1/54510/

a better repoducer is:

{
   auto C = new TCanvas();
   auto f1 = new TF1("f1","1 + 0.5*cos(30*x)",2.5,4);
   f1->SetNpx(250);
   f1->GetXaxis()->SetRangeUser(3,3.5);
   f1->SetMarkerStyle(20);
   f1->SetMarkerColor(2);

   auto f2 = new TF1("f2","1 + 0.5*cos(30*x)",2.5,4);
   f2->SetNpx(250);
   f2->GetXaxis()->SetRangeUser(3.3,3.4);
   f2->SetLineColor(4);
   f2->SetLineWidth(4);

   f1->Draw(" p");
   f2->Draw("same  L");
   C->SetGridx();
}
