TF1 parameter

Hi,

is it possible to draw the same function with changed parameters in the same pad?

E.g. I plot a straight a*x and I want to see the result for 5 different a’s.

Thanks…

One possible way:

{
   f = new TF1("f","[0]*x",-1,1);
   f->SetParameter(0,1);
   f->DrawClone();
   for (Int_t i=2; i<=5; i++) {
      f->SetParameter(0,i);
      f->DrawClone("same");
   } 
}
