Hello co-rooters!

I am trying to make a polar graph using `TGraphPolar`

in which only the line of the graph should be drawn, i.e. no axes or `Polargram`

.

To do so I used the `SetNdivPolar(0)`

and `SetNdivRadial(0)`

commands however only the radial components vanish, as seen in the following image.

I also tried to set the line size of the polargram through the editor to 0, however only the divisions vanished.

How is it possible to draw just the line of the `TPolarGraph`

?

A macro that illustrates the issue comes up next!

```
{
TF1 *Leg2 = new TF1("Leg2", "(3.*pow( TMath::Cos(x), 2 ) - 1. )/2.", 0, 2.*TMath::Pi());
TF1 *Leg4 = new TF1("Leg4", "(35.*pow(TMath::Cos(x) , 4) - 30.*pow( TMath::Cos(x), 2 ) + 3. )/8.", 0, 2.*TMath::Pi());
TF1 *f_0 = new TF1("f_0", "1. + 0.8*Leg2(x) - 0.2*Leg4(x)", 0, 2.*TMath::Pi());
double x[1000];
double y[1000];
for (int i=0; i<1000; ++i){
x[i] = i*TMath::Pi()/500.;
y[i] = f_0->Eval(x[i]);
}
TGraphPolar *gpolar = new TGraphPolar(1000, x, y);
gpolar->Draw("L");
c1->Update();
gpolar->GetPolargram()->SetNdivPolar(0);
gpolar->GetPolargram()->SetNdivRadial(0);
}
```

Any idea on how to solve that?

Thank you very much in advance!
