-## Combo bar/line
-
-`BarChart` and `LineChart` both support mixed bar/line datasets. Add `BarChartDataset` and `LineChartDataset` instances to the same `ChartData.Datasets` collection and initialize either chart component as the root chart.
-
-```razor
-<BarChart @ref="chart" Width="600" />
-
-@code {
-  private BarChart chart = default!;
-  private readonly BarChartOptions options = new()
-  {
-    Responsive = true,
-    Interaction = new Interaction { Mode = InteractionMode.Index, Intersect = false },
-  };
-
-  private readonly ChartData chartData = new()
-  {
-    Labels = new List<string> { "January", "February", "March" },
-    Datasets = new List<IChartDataset>
-    {
-      new BarChartDataset
-      {
-        Label = "Revenue",
-        Data = new List<double?> { 65, 59, 80 },
-      },
-      new LineChartDataset
-      {
-        Label = "Target",
-        Data = new List<double?> { 50, 55, 60 },
-      },
-    },
-  };
-
-  protected override async Task OnAfterRenderAsync(bool firstRender)
-  {
-    if (firstRender)
-      await chart.InitializeAsync(chartData, options);
-  }
-}
-```
-
-Use `LineChart` the same way when you want the line configuration to be the root chart type.
