TRSChartValues.Add(TRSChartValueType,String,TCanvasColor) Method

Creates a new TRSChartValue instance and adds it to the Items array. The new instance is initialized with the Value, 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 (based on a default value (0)).

Add returns the new value.

Note
Note that because every time you change a value an event is called, it is faster to add and initialize a value using the overloaded Add method.

Namespace: RSChartPanel

Parameters

Value

Type: TRSChartValueType

Caption

Type: String

Color

Type: TCanvasColor

Return Value

Type: TRSChartValue

The following example creates values in the collection:

Delphi

var
   Value: TRSDonutChartExValue;  // 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.StartAngle := 0.0;
   Value.SweepAngle := 90.0;
   Value.InnerRadius := 0.7;
   Value.OuterRadius := 0.9;
   // this code adds the same point but much more quickly
   Value := MyChart.Values.Add( 0.0, 90.0, 0.7, 0.9, 'One', clRed );
end;
