[ROOT] Newbie clue request per two TGraphs

Rootsters:

I seem to think this should display one panel with two sets of two colored 
dots:

{
   gROOT->Reset();	
   c1 = new TCanvas("c1","A Simple Plan",200,10,700,500);	
   c1->SetFillColor(42);
   c1->SetGrid();

   const Int_t na = 2;
  Double_t xa[na] = { 0.0,2.0 }, ya[na] = { 1.10000002384,3.29999995232 } ;
   gra = new TGraph(na,xa,ya);
   gra->SetFillColor(19);
   gra->SetLineStyle (3);
   gra->SetMarkerColor(4);
   gra->SetMarkerStyle(21);
   gra->SetTitle("A Simple Plan");
   gra->Draw("ACP");
		   
   const Int_t nb = 2;
   Double_t xb[nb] = { 1.0,3.0 }, yb[nb] = { 5.80000019073,4.19999980927 };
   grb = new TGraph(nb,xb,yb);
   grb->SetFillColor(19);
   grb->SetLineStyle (3);
   grb->SetMarkerColor(4);
   grb->SetMarkerStyle(21);
   grb->SetTitle("A Simple Plan");
   grb->Draw("ACP");
		   
   c1->Update();
   c1->GetFrame()->SetFillColor(21);
   c1->GetFrame()->SetBorderSize(12);
   c1->Modified();
   }

ROOT thinks otherwise; it only draws the second set. The code resembles 
that in tutorial examples such as zdemo.C.
