How to group stacking series in the Blazor Chart?

This article explains how to group the stacking series in the Blazor Chart.

Grouping stacking series in Blazor Chart

Stacking series are rendered in such a way that all the series are stacked. This is not desired when there are many stacking series in the chart. In such cases, the Blazor Chart provides options to group the stacking series by using StackingGroup property.

For example, consider four stacking column series grouped into two; Group1 and Group2 by using the StackingGroup property. Then, chart is rendered in two stacking columns at a point; one for Group1 and the other for Group2.

The following code example demonstrates how to group the stacking series in Blazor Chart.

Index.razor

@using Syncfusion.Blazor.Charts

<sfchart>

    <chartprimaryxaxis valuetype="Syncfusion.Blazor.Charts.ValueType.Category"></chartprimaryxaxis>

    <chartseriescollection>
        <chartseries datasource="@DataSource" stackinggroup="Group1" xname="X" yname="YValue" type="ChartSeriesType.StackingColumn">
        </chartseries>
        <chartseries datasource="@DataSource" stackinggroup="Group1" xname="X" yname="YValue1" type="ChartSeriesType.StackingColumn">
        </chartseries>
        <chartseries datasource="@DataSource" stackinggroup="Group2" xname="X" yname="YValue2" type="ChartSeriesType.StackingColumn">
        </chartseries>
        <chartseries datasource="@DataSource" stackinggroup="Group2" xname="X" yname="YValue3" type="ChartSeriesType.StackingColumn">
        </chartseries>
    </chartseriescollection>

</sfchart>

@code {

    public class ChartData
    {
        public string X { get; set; }
        public double YValue { get; set; }
        public double YValue1 { get; set; }
        public double YValue2 { get; set; }
        public double YValue3 { get; set; }
    }

    public List<chartdata> DataSource = new List<chartdata>
    {
        new ChartData { X= "USA", YValue= 46, YValue1=56, YValue2=26,YValue3=50},
        new ChartData { X= "GBR", YValue= 27, YValue1=17, YValue2=37,YValue3=20},
        new ChartData { X= "CHN", YValue= 26, YValue1=36, YValue2=56,YValue3=26},
        new ChartData { X= "UK", YValue= 56,  YValue1=16, YValue2=36,YValue3=16},
        new ChartData { X= "AUS", YValue= 12, YValue1=46, YValue2=26,YValue3=20},
        new ChartData { X= "IND", YValue= 26, YValue1=16, YValue2=76,YValue3=25},
        new ChartData { X= "DEN", YValue= 26, YValue1=12, YValue2=42,YValue3=20},
        new ChartData { X= "MEX", YValue= 34, YValue1=32, YValue2=82,YValue3=35},
    };
}
