Namespace: DevExpress.XamarinForms.Charts
Assembly: DevExpress.XamarinForms.Charts.dll
NuGet Package: DevExpress.XamarinForms.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.
