DataSourceAdapterBase.DataSource Property
Gets or sets the data source for the chart.
Namespace: DevExpress.XamarinForms.Charts
Assembly: DevExpress.XamarinForms.Charts.dll
NuGet Package: DevExpress.XamarinForms.Charts
Declaration
public object DataSource { get; set; }Property Value
| Type | Description |
|---|---|
| Object | The data source object. |
Remarks
Data source adapters support data collections that implement the IBindingList or INotifyCollectionChanged interface, and allow you to bind charts to IList, IList<T>, and DataTable collections directly.
Example
This example shows how to provide data for the PieSeries.
Note
If you want to provide data for the ChartView, use the SeriesDataAdapter class.
Set the PieSeries.Data property to a new PieSeriesDataAdapter instance. Use the DataSource, ValueDataMember, and LabelDataMember properties to specify the data source for the chart, and to define data source members used to generate series points and labels.
