Creates a new RSCharts.TRS2DChartValue instance and adds it to the Items array. The new instance is initialized with the X, Y, Caption, and Color parameters. Call Add to create a 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.

Add returns the new 2D value.

Namespace: RSCharts

Parameters

Type: TRSChartValueType

Caption

Type: String

Return Value

The following example creates values in the collection:

Delphi
var Value: TRS2DChartValue; // 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; // this code adds the same point but much more quickly Value := MyChart.Values.Add( 10.0, 20.0, 'One', clRed ); end;
