The class TPolyLine does not include the functions to color
the filled area. This functionality is part of the TGraph class.
I have modified your macro accordingly.

{
gROOT->Reset();
Float_t x[7] = {0.2,0.3,0.3,0.2,0.1,0.1,0.2};
Float_t y[7] = {0.4,0.3,0.2,0.1,0.2,0.3,0.4};
TGraph *gr = new TGraph(7,x,y);
gr->SetFillColor(6);
gr->SetFillStyle(3008);
gr->Draw("f");
}
