PivotGridControl.ChartDataSource Property

Gets a data source for a chart control.

Namespace: DevExpress.Xpf.PivotGrid

Assembly: DevExpress.Xpf.PivotGrid.v24.2.dll

NuGet Package: DevExpress.Wpf.PivotGrid

Declaration

C#

public IBindingList ChartDataSource { get; }

VB.NET

Public ReadOnly Property ChartDataSource As IBindingList

Property Value

Type	Description
IBindingList	The data source for a chart control.

Remarks

To set the PivotGridControl as the data source for a chart control, assign the ChartDataSource property’s value to the ChartControl.DataSource property.

Example

This example demonstrates how to bind a ChartControl to a PivotGridControl. For this, assign the PivotGridControl.ChartDataSource property value to the ChartControl.DataSource property.

The Transpose Data Source checkbox is bound to the PivotGridControl.ChartProvideDataByColumns property. If the checkbox is checked, the property is set to false, and chart series are based on pivot grid rows instead of columns.
