SeriesPointData.PointKeyObjects Property

Gets information about a raw data source value(s) based on which the chart creates a series point.

Namespace: DevExpress.Maui.Charts

Assembly: DevExpress.Maui.Charts.dll

NuGet Package: DevExpress.Maui.Charts

Declaration

public IList<object> PointKeyObjects { get; }

Property Value

Type	Description
IList<Object>	A list of objects that specify data source items.

Remarks

If you use a built-in data adapter (SeriesDataAdapter or PieSeriesDataAdapter) to populate a series with data, the PointKeyObjects property returns a list of DataSourceKey objects. If you use a custom data adapter, the PointKeyObjects list items are objects that the adapter’s GetKey method (IXYSeriesData.GetKey or IPieSeriesData.GetKey) returns.

The PointKeyObjects property returns a list with several objects if the chart’s series point aggregates several values of the data source (for example, data source values are measured in minutes while the chart aggregates data and creates points measured in hours or days). If a series point corresponds to a single item of the data source, the PointKeyObjects list contains only an object that specifies that item. For a calculated series (indicator), the PointKeyObjects property returns an empty list.
