Remarks
The DxPivotGridDataProvider class acts as a bridge between the Pivot Grid and Chart components.
Use the Create<TDataSource>(Task<TDataSource>) method to create a new provider object. The method’s parameter is an asynchronous task that returns an IEnumerable<T> data source. Bind the Pivot Grid and Chart to the provider’s PivotGridDataSource and ChartDataSource properties that return data in formats applicable to these components.
<DxChart Data="@(PivotGridDataProvider.ChartDataSource)">
<DxChartCommonSeries NameField="@((IChartDataItem s) => s.SeriesName)"
ArgumentField="@(s => s.Argument)"
ValueField="@(s => s.Value)"
SeriesType="ChartSeriesType.Bar" />
</DxChart>
<DxPivotGrid Data="@(PivotGridDataProvider.PivotGridDataSource)">
<DxPivotGridField Field="@nameof(SaleInfo.Region)" SortOrder="PivotGridSortOrder.Ascending"
Area="PivotGridFieldArea.Row"></DxPivotGridField>
<DxPivotGridField Field="@nameof(SaleInfo.Country)" Area="PivotGridFieldArea.Row"></DxPivotGridField>
<DxPivotGridField Field="@nameof(SaleInfo.City)" Area="PivotGridFieldArea.Row"></DxPivotGridField>

</DxPivotGrid>
@code {
DxPivotGridDataProvider<SaleInfo> PivotGridDataProvider = DxPivotGridDataProvider<SaleInfo>.Create(Sales.Load());
}
The Chart shows data from the Pivot Grid’s lowest expanded level. The Chart is updated when a user expands or collapses rows/columns in the Pivot Grid.
