Hi,
Can one create and fill a polygon in root? I have tried to use
TPolyLine the following way but it doesn't seem to work:
TCanvas *mycanvas = new TCanvas("mycanvas", "My Canvas",400,10,800,800);
Int_t NPoints = 4;
Float_t X[4]; X[0]=0.35; X[1]=0.45; X[2]=0.55; X[3]=0.35;
Float_t Y[4]; Y[0]=0.4; Y[1]=0.6; Y[2]=0.4; Y[3]=0.4;
TPolyLine *plin = new TPolyLine(NPoints,X,Y);
plin->SetLineColor(3); //green
plin->SetLineWidth(2);
plin->SetFillColor(4); //blue
plin->Draw();
It seems that the SetFillColor(4) has no effect. Is this a bug, or is this
functionality not there (can it be put in?), or am I doing something
wrong. Grateful for help.
