Declaration

C#

[ResourceFinder(typeof(XtraChartsResFinder), "PropertyNamesRes")]
public enum SortingMode

VB.NET

<ResourceFinder(GetType(XtraChartsResFinder), "PropertyNamesRes")>
Public Enum SortingMode

Members

Name	Description
None	The values are not sorted.
Ascending	The values are sorted in ascending order.
Descending	The values are sorted in descending order.

Related API Members

The following properties accept/return SortingMode values:

Library	Related API Members
Cross-Platform Class Library	SeriesBase.SeriesPointsSorting
WinForms Controls	ChartControl.SeriesSorting
	SeriesBaseModel.SeriesPointsSorting
ASP.NET MVC Extensions	ChartControlSettings.SeriesSorting
ASP.NET Web Forms Controls	WebChartControl.SeriesSorting
.NET Reporting Tools	XRChart.SeriesSorting

Remarks

The values listed by this enumeration are used to set the ChartControl.SeriesSorting and SeriesBase.PointsSorting properties.

Example

The following example shows how to create a Pie chart at runtime.

View Example

The Chart Control uses the Simple Diagram to display pies. Cast the ChartControl.Diagram property to the SimpleDiagram type to access diagram settings. The Chart Control determines the diagram type based on the series that is added first. We recommend that you access the diagram to configure its settings after at least one series is added to the chart.

To access pie series view settings, cast the SeriesBase.View property to the PieSeriesView type.
