SeriesBase.SeriesPointsSorting Property

Gets or sets the sort order of the series’ points.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v20.1.dll

NuGet Packages: DevExpress.Charts, DevExpress.WindowsDesktop.Charts

Declaration

C#

[XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)]
public SortingMode SeriesPointsSorting { get; set; }

VB.NET

<XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)>
Public Property SeriesPointsSorting As SortingMode

Property Value

Type	Description
SortingMode	A SortingMode enumeration value.

Available values:

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

Remarks

The Chart Control can sort series points based on their arguments or data values, specified in the SeriesBase.SeriesPointsSortingKey property. Use the SeriesPointsSorting property to choose the sort mode for data points.

When there are multiple series with the same arguments in the chart’s collection, and a sort order is applied to one of these series, points are sorted within all series.

Note

If series have different point arguments, the Chart Control sorts points within a single series only. Use the QualitativeScaleComparer to sort all series in this case.

The following images demonstrate the three modes available for the SeriesPointsSorting property, with the series points sorted by their values.

SeriesPointsSorting = None	SeriesPointsSorting = Ascending SeriesPointsSortingKey = Value_1	SeriesPointsSorting = Descending SeriesPointsSortingKey = Value_1

For more information, refer to the following help topic: Sorting Data.

Example

The following properties allow you to sort series points within a series.

Property	Description
SeriesBase.SeriesPointsSortingKey	Specifies the point sort order.
SeriesBase.SeriesPointsSorting	Specifies the value by which series points should be sorted.
