Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v21.2.dll

NuGet Package: DevExpress.Charts

Declaration

C#

[XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)]
public SeriesPointKey SeriesPointsSortingKey { get; set; }

VB.NET

<XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)>
Public Property SeriesPointsSortingKey As SeriesPointKey

Property Value

Type	Description
SeriesPointKey	A SeriesPointKey enumeration value.

Available values:

Name	Description
Argument	Specifies that sorting is performed by the argument values of a series’ data points.
Value_1	Specifies that series points are sorted based on the first data value within the SeriesPoint.Values array of a series’s data points. For financial data, Value_1 indicates the Low value. For BoxPlot series, it indicates the Min value.
Value_2	Specifies that series points are sorted based on the second data value within the SeriesPoint.Values array of a series’s data points. For financial data, Value_2 indicates the High value. For BoxPlot series, it indicates the Quartile1 value.
Value_3	Specifies that series points are sorted based on the third data value within the SeriesPoint.Values array of a series’s data points. For financial data, Value_3 indicates the Open value. For BoxPlot series, it indicates the Median value.
Value_4	Specifies that series points are sorted based on the fourth data value within the SeriesPoint.Values array of a series’s data points. For financial data, Value_4 indicates the Close value. For BoxPlot series, it indicates the Quartile3 value.
Value_5	Specifies that series points are sorted based on the fifth data value within the SeriesPoint.Values array of a series’s data points. For BoxPlot series, it indicates the Max value.
Value_6	Specifies that series points are sorted based on the sixth data value within the SeriesPoint.Values array of a series’s data points. For BoxPlot series, it indicates the Mean value.

Remarks

Series points can be sorted based upon either their arguments or data values. Use the SeriesPointsSortingKey property to specify which values of the series’ data points should be used to sort the series data.

The sort order can be specified via the SeriesBase.SeriesPointsSorting property.

Note

Since, for some series view types, multiple values for each data point are required, there are four value modes for the SeriesBase.SeriesPointsSortingKey property. So, at runtime, to sort by values points of a series whose view type supports only a single value, choose the SeriesPointKey.Value_1 setting.

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.
