How to select the entire stacking series segment in Blazor Chart?

This KB article explains how to select the entire stacking series segment in the Blazor Chart Component.

Selecting entire stacking series in Blazor Chart

It has been achieved by setting the SelectionMode to Cluster. You can select entire stacking series segment in Blazor Chart by using this Cluster selection mode.

You can style the selection series by using the SelectionStyle property in ChartSeries, which accepts a CSS class for customization.

The following code example illustrates this.

Index.razor

@using Syncfusion.Blazor.Charts

<SfChart SelectionMode="SelectionMode.Cluster">
    <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category"></ChartPrimaryXAxis>
    
    <ChartSeriesCollection>
        <ChartSeries DataSource="@MedalDetails" XName="X" YName="YValue" Type="ChartSeriesType.StackingColumn" SelectionStyle="chartSelection">
        </ChartSeries>
        <ChartSeries DataSource="@MedalDetails" XName="X" YName="YValue1" Type="ChartSeriesType.StackingColumn" SelectionStyle="chartSelection">
        </ChartSeries>
    </ChartSeriesCollection>
</SfChart>

<style>
    .chartSelection {
        fill: red
    }     
</style>

@code {

    public class ChartData
    {
        public string X { get; set; }
        public double YValue { get; set; }
        public double YValue1 { get; set; }
    }

    public List<ChartData> MedalDetails = new List<ChartData>
    {
        new ChartData { X= "USA", YValue= 46, YValue1=56 },
        new ChartData { X= "GBR", YValue= 27, YValue1=17 },
        new ChartData { X= "CHN", YValue= 26, YValue1=36 },
        new ChartData { X= "UK", YValue= 56,  YValue1=16 },
        new ChartData { X= "AUS", YValue= 12, YValue1=46 },
        new ChartData { X= "IND", YValue= 26, YValue1=16 },
        new ChartData { X= "DEN", YValue= 26, YValue1=12 },
        new ChartData { X= "MEX", YValue= 34, YValue1=32},
    };
