How to: Visualize Pivot Grid Data using the Chart Control

  • Dec 17, 2020
  • 3 minutes to read

The following example shows how to bind a Chart control to a Pivot Grid to visualize data.

In this example, after an ASPxPivotGrid and WebChartControl are created, the pivot grid’s ID is assigned to the WebChartControl.DataSourceID property. By default, the PivotGridDataSourceOptions.AutoBindingSettingsEnabled property is set to true, so that binding settings are automatically adjusted, and no further customization is needed. Once the WebChartControl is bound to the ASPxPivotGrid, pivot grid data is immediately displayed in the Chart.

The sample web page contains the ‘Transpose Data Source’ check box that defines the pivot grid’s PivotGridOptionsChartDataSourceBase.ProvideDataByColumns property value. If the check box is checked, the property is set to false, and series are created based on pivot grid rows (instead of columns, which is the default behavior).
