TRSDonutChartExValues.Add(TRSChartValueType,String,TCanvasColor) Method

Comments (0)

Creates a new TRSDonutChartExValue instance and adds it to the Items array. The new instance is initialized with the SweepAngle, Caption, and Color parameters. The StartAngle defaults to the end angle of the last item in the collection.

Call Add to create a donut slice 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 donut slice value.

noteNote

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: RSDonutCharts

expandingExamples

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;
