Delphi

var
   Value: TRSPathChartValue;  // note, this type should be the same that the chart uses (e.g., TRS2DChartValue, TRSArrowChartValue, etc)
 begin
   Value := MyChart.Values.Add;
   Value.Caption := 'Hexagon';
   Value.Color := clRed;
   Value.X := 10.0;
   Value.Y := 20.0;
   Value.Width := 30;

   // this code adds the same point but much more quickly
   Value := MyChart.Values.Add( RSRect(10,20,40,60), 'M850,75 L958,137.5 L958,262.5 L850,325 L742,262.600006103516 L742,137.5 Z', 'Hexagon', clRed );
