Razor

<DxChart Data="@ChartsData">
    <DxChartBarSeries Name="2019"
                      Filter="@((SaleInfo s) => s.Date.Year == 2019)"
                      ArgumentField="@(s => s.City)"
                      ValueField="@(s => s.Amount)"
                      SummaryMethod="Enumerable.Sum" />
    @* ... *@
</DxChart>

Data Source

@code {
    IQueryable<SaleInfo> ChartsData;

    protected override async Task OnInitializedAsync() {
        ChartsData = await MyDataService.Load();
    } 
}

You can also link the Chart to the DxPivotGrid<T> component. Create a DxPivotGridDataProvider<T> object and set the Chart’s Data property to the provider’s ChartDataSource property value. Refer to the Visualize Pivot Grid Data section for more information.

<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>
    <DxPivotGridField Field="@nameof(SaleInfo.Date)" GroupInterval="PivotGridGroupInterval.Year" 
        Area="PivotGridFieldArea.Column" Caption="Year"> </DxPivotGridField>
    <DxPivotGridField Field="@nameof(SaleInfo.OrderId)" Caption="Count" Area="PivotGridFieldArea.Data" 
        SummaryType="PivotGridSummaryType.Count"> </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.
