IChartCircleInfo.SeriesAsRings

Fore Syntax

SeriesAsRings: Boolean;

Fore.NET Syntax

SeriesAsRings: boolean;

Description

The SeriesAsRings property determines whether series are displayed in the chart rings.

Comments

Available values:

True. Chart series are displayed in rings.
False. Chart series are displayed in sectors.

The property is not relevant for the doughnut chart (IChart.Type = ChartType.HoleSize).

The following figure shows examples of displaying a chart with series in rings (left) and sectors (right):

Fore Example

To execute the example, place a button, the ChartBox and UiChart components on the form. Add event handlers, which are used in the example.

Add links to the Chart and MathFin system assemblies.

Sub UiChart1OnGetDataValue(Sender: Object; Args: IUiChartGetDataValueEventArgs);
Begin
    Args.Result := True;
    Args.Value := Math.Rand;
    ChartBox1.Source := UiChart1 As IChartSource;
    UiChart1.Type := ChartType.Circles;
End Sub UiChart1OnGetDataValue;
…
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Begin
    UiChart1.Chart.CircleInfo.SeriesAsRings := True;
End Sub Button1OnClick;

On executing the example a pie chart with series in sectors is displayed. After clicking the button series are displayed in rings.

Fore.NET Example

To execute the example, place a button, the ChartBoxNet and UiChartNet components on the form. Specify a data source for ChartBoxNet. Add event handlers, which are used in the example.
