Creates a new TRSPointChartValue instance and adds it to the Items array. The new instance is initialized with the X, Caption, Color, and ImageIndex parameters. Call Add to create a point value in the collection. The new value is placed at the end of the Items array, or, if the collection is Sorted, placed at the sorted point in the collection (based on a default value (0, 0)).
Add returns the new point value.

Caption
Type: String
Color

var
Value: TRSPointChartValue; // note, this type should be the same that the chart uses (e.g., TRS2DChartValue, TRSArrowChartValue, etc)
begin
Value := MyChart.Values.Add;
Value.Caption := 'One';
Value.Color := clRed;
Value.X := 10.0;
Value.Y := 20.0;
Value.ImageIndex := 0;
// this code adds the same point but much more quickly
Value := MyChart.Values.Add( 10.0, 20.0, 'One', clRed, 0 );
end;
