Displaying datetime data by weeks

Blazor Charts provides an option to display the datetime axis labels in weeks using Interval and IntervalType.

This can be achieved by specifying the Interval as 7 and IntervalType as Days in the DateTime axis. This will display the datetime values with weekly intervals. An axis labels can be customized using the OnAxisLabelRender event.

The code example below demonstrates how to display datetime data in weeks format.

@using Syncfusion.Blazor.Charts

<SfChart>
   <ChartEvents OnAxisLabelRender="LabelRenderEvt"></ChartEvents>
   <ChartPrimaryXAxis IntervalType="Syncfusion.Blazor.Charts.IntervalType.Days" Interval=7 ValueType="Syncfusion.Blazor.Charts.ValueType.DateTime">
   </ChartPrimaryXAxis>
</SfChart>

@code {
   String[] stringarr = new String[] { "Week1", "Week2", "Week3", "Week4" };
   public int count = 0;

   public void LabelRenderEvt(Syncfusion.Blazor.Charts.AxisLabelRenderEventArgs args)
   {
       if (count > 3)
           count = 0;
       if(args.Axis.Name == "PrimaryXAxis")
       {
           args.Text = stringarr[count];
           count++;
       }
   }
   public class ChartData
   {
       public DateTime XValue { get; set; }
       public double YValue { get; set; }
   }
   public List<ChartData> WeatherReports = new List<ChartData>
   {
       new ChartData { XValue = new DateTime(2005, 01, 05), YValue = 21 },
       new ChartData { XValue = new DateTime(2005, 01, 10), YValue = 24 },
       //...
