Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v20.1.dll

Declaration

[Obsolete("This enumeration is now obsolete. Use the SeriesPointKey enumeration instead.")]
public enum SortingKey
<Obsolete("This enumeration is now obsolete. Use the SeriesPointKey enumeration instead.")>
Public Enum SortingKey

Members

Name Description
Argument

Specifies that sorting is performed by the argument values of a series' data points.

Value_1

Specifies that sorting is performed by the first data value within the SeriesPoint.Values array of a series's data points. For financial data this indicates the Low value.

Value_2

Specifies that sorting is performed by the second data value within the SeriesPoint.Values array of a series's data points. For financial data this indicates the High value.

Value_3

Specifies that sorting is performed by the third data value within the SeriesPoint.Values array of a series's data points. For financial data this indicates the Open value.

Value_4

Specifies that sorting is performed by the fourth data value within the SeriesPoint.Values array of a series's data points. For financial data this indicates the Close value.

Remarks

The values listed by this enumeration can be used to set the SeriesBase.PointsSortingKey property.

Examples

The following example demonstrates how to create a ChartControl with a series of the PieSeriesView type, and add this chart to a form at runtime.

Note that this series view type is associated with the SimpleDiagram type, and you should cast your diagram object to this type, in order to access its specific options.
