TPolyLine not filled in NDC mode

Dear all,

I found that a TPolyline is not filled when NDC mode is used.
This can be seen by the following example:

{ TPolyLine pl(5); pl.SetNDC(kTRUE); pl.SetFillStyle(1001); pl.SetFillColor(kCyan); pl.SetPoint(0, 0.1, 0.1); pl.SetPoint(1, 0.5, 0.1); pl.SetPoint(2, 0.5, 0.2); pl.SetPoint(3, 0.1, 0.2); pl.SetPoint(4, 0.1, 0.1); pl.Draw("f"); // not filled! } .
Is there any way to solve this problem?
I need to use NDC mode to draw objects on a histogram drawin with cont4 option…

Yes, I just look at it. The option “f” is not implemented in the NDC case.
