Here is an example:
void graphsame()
{
c1 = new TCanvas("c1","2 Graphs",200,10,700,500);
const Int_t n = 20;
Double_t x[n], y[n], y1[n];
for (Int_t i=0;i<n;i++) {
x[i] = i*0.1;
y[i] = 10*sin(x[i]+0.2);
y1[i] = y[i]+1;
}
gr = new TGraph(n,x,y);
gr1 = new TGraph(n,x,y1);
gr->Draw("ACP");
gr1->Draw("CP");
}
