Creates a new TRSChartValue instance and adds it to the Items array. The new instance is initialized with the Values, 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.
Namespace: RSChartPanel
Delphi
|
public
function Add( Values: array of TRSChartValueType; Caption: String = '';
Color: TCanvasColor = clxDefaultColor ): TRSChartValue; overload;
|
Parameters
Values
Type: array of 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;
