This article explains how to render x-axis labels with sorting in Blazor Charts.

Render X-Axis Labels with Sorting

Blazor Charts provides an option to render x-axis labels with sorting.

To render x-axis labels with sorting, you need to utilize the OnAxisLabelRender event and use the X property for the X-axis. This event can change the axis label based on the X property value, allowing it to render the x-axis labels with sorting.

The below code example demonstrates how to render x-axis labels with sorting

Index.razor

@using Syncfusion.Blazor.Charts
@using Syncfusion.Blazor.Buttons

<SfChart>
   <ChartEvents OnAxisLabelRender="AxisLabelEvent" />
   <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Double" />
   <ChartSeriesCollection>
       <ChartSeries DataSource="@Data1" XName="X" YName="Y" Type="Syncfusion.Blazor.Charts.ChartSeriesType.Line" />
   </ChartSeriesCollection>
</SfChart>

@code {
   public void AxisLabelEvent(Syncfusion.Blazor.Charts.AxisLabelRenderEventArgs args)
   {
       if(args.Axis.Name == "PrimaryXAxis")
       {
           args.Text = Data1[int.Parse(args.Text)].XLabel;
       }
   }

   public class ChartData
   {
       public double X { get; set; }
       public string XLabel { get; set; }
       public double Y { get; set; }

   }
   public List<ChartData> Data1 = new List<ChartData>
   {
       new ChartData { X=0, XLabel= "11/20/2013", Y= 30},
       new ChartData { X=1, XLabel= "02/27/2014", Y= 23.6 },
       new ChartData { X=2, XLabel= "03/11/2014", Y= 34 },
       new ChartData { X=3, XLabel= "04/14/2014", Y= 18 },
       new ChartData { X=4, XLabel= "05/06/2014", Y= 10 },
       new ChartData { X=5, XLabel= "05/06/2014", Y= 15 },
       new ChartData { X=6, XLabel= "05/14/2015", Y= 40 },
       new ChartData { X=7, XLabel= "05/10/2016", Y= 41 },
       new ChartData { X=8, XLabel= "09/29/2016", Y= 0 },
       new ChartData { X=9, XLabel= "10/05/2016", Y= 0 },
       new ChartData { X=10, XLabel= "10/05/2016", Y= 2 },
       new ChartData { X=11, XLabel= "11/03/2016", Y= 88 },
       new ChartData { X=12, XLabel= "03/20/2017", Y= 70 },
       new ChartData { X=13, XLabel= "04/10/2017", Y= 70 },
       new ChartData { X=14, XLabel= "05/15/2017", Y= 80 },
       new ChartData { X=15, XLabel= "09/11/2017", Y= 80 },
       new ChartData { X=16, XLabel= "02/21/2019", Y= 80 },
       new ChartData { X=17, XLabel= "01/15/2020", Y= 52 },
       new ChartData { X=18, XLabel= "08/31/2021", Y= 70 }
