To draw a polar graph.

TGraphPolar creates a polar graph (including error bars). A TGraphPolar is a TGraphErrors represented in polar coordinates. It uses the class TGraphPolargram to draw the polar axis.

Example:

{
   TCanvas * CPol = new TCanvas("CPol","TGraphPolar Example",500,500);
   Double_t theta[8];
   Double_t radius[8];
   Double_t etheta[8];
   Double_t eradius[8];
   for (int i=0; i<8; i++) {
      theta[i]   = (i+1)*(TMath::Pi()/4.);
      radius[i]  = (i+1)*0.05;
      etheta[i]  = TMath::Pi()/8.;
      eradius[i] = 0.05;
   }
   TGraphPolar * grP1 = new TGraphPolar(8, theta, radius, etheta, eradius);
   grP1->SetTitle("TGraphPolar Example");
   grP1->SetMarkerStyle(20);
   grP1->SetMarkerSize(2.);
   grP1->SetMarkerColor(4);
   grP1->SetLineColor(2);
   grP1->SetLineWidth(3);
   grP1->Draw("PE");
   // Update, otherwise GetPolargram returns 0
   CPol->Update();
   grP1->GetPolargram()->SetToRadian();
   return CPol;
}
