This demo illustrates linked Chart and Pivot Grid components. The chart is automatically updated when a user expands or collapses rows/columns in the Pivot Grid, and the Chart shows data from the Pivot Grid's lowest expanded level.

To link these components, do the following:

1. Create a custom method that asynchronously returns an IEnumerable collection (Sales.Load() in this demo).
2. Create a data provider object (PivotGridDataProvider in this demo).
3. Bind the Pivot Grid to the data provider object's PivotGridDataSource property.
4. Bind Charts to the data provider object's ChartDataSource property.
5. Assign corresponding fields to NameField, ArgumentField, and ValueField properties.
6. Additionally, you can assign a data field name to the PaneField property. This enables the Chart to group data by the corresponding field's values and create a separate Pane for each group.
