Namespace: DevExpress.UI.Xaml.Charts

Assembly: DevExpress.UI.Xaml.Charts.v21.2.dll

NuGet Package: DevExpress.Uwp.Controls

#Declaration

C#
VB.NET

[ContentProperty(Name = "Points")]
public class DataPointCollection :
    ChartDataAdapter

#Remarks

To provide data for a Series, it’s necessary to specify one of the ChartDataAdapter class descendants to the Series.Data property. There are two ways of doing this:

Explicitly add all data points to the series.

To do this, assign the DataPointCollection object to the Series.Data property and add all data points to the DataPointCollection.Points collection.
Populate a series with data from a datasource.

To do this, assign the DataSourceAdapter object to the Series.Data property and specify its settings, such as DataSourceAdapter.DataSource and DataSourceAdapter.DataMembers.

For more information, refer to Providing Data.

#Example

The following example demonstrates how to create a simple Pie Chart with one series.
