Family of function in one pad

ROOT
1

hello
I tried to plot a family of functions in the same Pad by defining a function with one free parameter and then tried to set this parameter and draw as follows:

TF1 *f1 = new TF1("f1","[0]*sin(x)",0,1);
f1->SetParameter(0,0);
f1->Draw();
for (int i=1;i<10>
        f1->SetParameter(0,i);
	f1->SetLineColor(i+1);
	f1->Draw("same");
}

!!of course it should be “for (int i=1;i<10;i++)”, but anytime I type it like this it is displayed another way!?

it seems that root updates the drawn function everytime so I only can see the last curve.
Does anybody have an idea about how I can see all this functions in the Pad, perhaps a better method than I tried?
thanks a lot!

Replace

f1->Draw("same"); by

f1->DrawCopy("same");
