TGraphPolar Class Reference

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();
return CPol;
}
