Customize to remove comma in indexed category axis labels in Blazor Chart

To display the x-values of the first series in the axis labels, instead of showing all x-values separated by commas, you can use the OnAxisLaberRender event in the Indexed Category Axis. This event allows customization of the axis labels according to your preferences.

The code snippet below demonstrates how to remove commas from Indexed Category Axis labels using the OnAxisLaberRender event.

Index.razor

@using Syncfusion.Blazor.Charts

<SfChart>

    <ChartPrimaryXAxis IsIndexed="true" ValueType="Syncfusion.Blazor.Charts.ValueType.Category">
    </ChartPrimaryXAxis>

    <ChartEvents OnAxisLabelRender="OnLabelRender"></ChartEvents>

    <ChartSeriesCollection>
        <ChartSeries DataSource="@WeatherReports1" XName="X" YName="Y" Type="ChartSeriesType.Column">
        </ChartSeries>
        <ChartSeries DataSource="@WeatherReports2" XName="X" YName="Y" Type="ChartSeriesType.Column">
        </ChartSeries>
    </ChartSeriesCollection>

</SfChart>

@code {
    
    public class WeatherData
    {
        public string X { get; set; }
        public double Y { get; set; }
    }

    public List<WeatherData> WeatherReports1 = new List<WeatherData>
    {
        new WeatherData{ X= "Myanmar", Y= 7.3 },
        new WeatherData{ X= "India", Y= 7.9 },
        new WeatherData{ X= "Bangladesh", Y= 6.8 },
        new WeatherData{ X= "Cambodia", Y=7.0 },
        new WeatherData{ X= "China", Y= 6.9 }
    };

    public List<WeatherData> WeatherReports2 = new List<WeatherData>
    {
        new WeatherData{ X= "Poland", Y=2.7 },
        new WeatherData{ X= "Australia", Y=2.5 },
        new WeatherData{ X= "Singapore", Y=2.0 },
        new WeatherData{ X= "Canada", Y=1.4 },
        new WeatherData{ X= "Germany", Y=1.8 }
    };

    public void OnLabelRender(AxisLabelRenderEventArgs args)
    {
        if(args.Axis.Name == "PrimaryXAxis")
        {
            args.Text = args.Text.Split(',')[0].Trim();
