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"); 
}
