TRSPathChartValues.Add(TRSRect,String,String,TCanvasColor) Method

Creates a new RSCharts.TRSPathChartValue instance and adds it to the Items array. The new instance is initialized with the dimensions (Top, Left, Width, and Height), Path Data, Caption, and Color parameters. Call Add to create a path shape 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)).

Add returns the new path shape value.

Namespace: RSCharts

ARect

Type: TRSRect

Return Value

Type: TRSPathChartValue

The following example creates values in the collection:

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;
   Value.Height := 40;
   Value.Data := 'M850,75 L958,137.5 L958,262.5 L850,325 L742,262.600006103516 L742,137.5 Z';
   // 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 );
end;
