  Hi,
 
  The fill area attributes (like SetFillStyle, SetFillColor) etc ..) have 
 no effect on the markers. Filled area and markers are different basic 
 primitives and have different sets of attributes. To do what you requested 
 you should use two different marker types, one filled and the other 
 hollow, and superimpose them. The following macro gives you an example:
 
 {
      TCanvas *c1 = new TCanvas("c1","Test",0,0,600,600);
      TF1 fun1("fun1","sin(x)",0,6.28);      
      fun1.SetMarkerColor(5);  
      fun1.SetMarkerSize(2.);
      fun1.SetMarkerStyle(29); 
      fun1.Draw("P"); 
      TF1 fun2("fun1","sin(x)",0,6.28);
      fun2.SetMarkerColor(1);
      fun2.SetMarkerSize(2.);
      fun2.SetMarkerStyle(30);
      fun2.Draw("P SAME");
 }
 
  Cheers,         O.Couet
