Contains all the pie slices in the pie chart. Each pie slice ( RSCharts.TRSPieChartValue ) may have its own Color and Caption. The size of the pie slice is dependent on the Value, e.g., how much that value is proportional to the sum of all pie slice values in the pie chart. Use the Values collection to add, delete, and modify pie slices in the chart.

Property Value
Type: TRSPieChartValues
The following code adds 3 pie slices to the chart:
Delphi
|
var
Value: TRSPieChartValue; // note, this type should be the same that the chart uses (e.g., TRS2DChartValue, TRSArrowChartValue, etc)
begin
// Add first point
Value := RSPieChart1.Values.Add;
Value.Color := clRed;
Value.Value := 10.0;
// Add second point, twice as large as first
Value := RSPieChart1.Values.Add;
Value.Color := clGreen;
Value.Value := 20.0;
// Add third point, twice as large as second
Value := RSPieChart1.Values.Add;
Value.Color := clNavy;
Value.Value := 40.0;
// Draw the pie slices starting at 12:00 and go counter-clockwise
RSPieChart1.Offset := 90;
end;
