Hi rooters!
The macro below is taken from the root tutorials and my output differs
from the one posted on the web in that I cannot get the boundaries of the
histogram to be painted in a different color than the canvas.
I suppose c1->GetFrame->SetFillColor(...) is supposed to do this, but
the whole canvas is painted with the color set by c1->setFillColor(...).
What am I doing wrong?

gROOT->Reset();
c1 = new TCanvas("c1","A Simple Graph Example",200,10,700,500);
c1->SetFillColor(4);
c1->SetGridx();
c1->SetGridy();
c1->GetFrame()->SetFillColor(2);
c1->GetFrame()->SetBorderSize(12);
Float_t x[20], y[20];
for (Int_t i=0;i<n;i++) {
x[i] = i*0.1;
y[i] = 10*sin(x[i]+0.2);
printf(" i %i %f %f \n",i,x[i],y[i]);
}
gr = new TGraph(n,x,y);
gr->SetFillColor(19);
gr->SetLineColor(2);
gr->SetLineWidth(4);
gr->SetMarkerColor(4);
gr->SetMarkerStyle(21);
gr->Draw("ACP");
c1->Update();
gr->GetHistogram()->SetXTitle("X title");
gr->GetHistogram()->SetYTitle("Y title");
