DataPointCollection Class

Provides a collection of data points for a series.

Namespace: DevExpress.UI.Xaml.Charts

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

NuGet Package: DevExpress.Uwp.Controls

Declaration

C#

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

VB.NET

<ContentProperty(Name:="Points")>
Public Class DataPointCollection
    Inherits 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.
