How to sort pie chart points in Blazor Charts?

This article explains how to sort pie chart points in Blazor Charts.

Sorting Accumulation Chart Points

Blazor Charts provides an option to sort accumulation chart data points both at initial rendering and dynamically. This can be achieved using the OrderBy clause, which sorts the group in either ascending or descending order.

In the OnInitialized method, you can sort the points using y value and assign the sorted list to the chart datasource for sorting values at initial rendering. For dynamic sorting, the same scenario can be achieved through a button click.

The code example below demonstrates how to sort accumulation chart points.

Index.razor:

@using Syncfusion.Blazor.Charts
<SfAccumulationChart Title="Mobile Browser Statistics" EnableSmartLabels="true">
   <AccumulationChartLegendSettings Visible="false"></AccumulationChartLegendSettings>
   <AccumulationChartSeriesCollection>
       <AccumulationChartSeries DataSource="@StatisticsDetails" XName="Browser" YName="Users" Name="Browser">
           <AccumulationDataLabelSettings Visible="true" Name="Browser"></AccumulationDataLabelSettings>
       </AccumulationChartSeries>
   </AccumulationChartSeriesCollection>
</SfAccumulationChart>
@code {
   public class Statistics
   {
       public string Browser { get; set; }
       public double Users { get; set; }
       public string Text { get; set; }
       public string Fill { get; set; }
   }
   public List<Statistics> StatisticsDetails = new List<Statistics>
   {
       new Statistics { Browser = "Chrome", Users = 37, Text= "37%", Fill="#498fff"},
       new Statistics { Browser = "UC Browser", Users = 17, Text= "17%", Fill="#ffa060"},
       new Statistics { Browser = "iPhone", Users = 19, Text= "19%", Fill="#ff68b6"},
       new Statistics { Browser = "Opera", Users = 11, Text= "11%", Fill="#b2cfff"},
       new Statistics { Browser = "Android", Users = 12, Text= "12%", Fill="#ff7b66"},
       new Statistics { Browser = "Edge", Users = 8, Text= "8%", Fill="#4e7ac7"},
       new Statistics { Browser = "Safari", Users = 16, Text= "16%", Fill="#81e2a1"},
       new Statistics { Browser = "Firefox", Users = 9, Text= "9%", Fill="#ff8040"},
       new Statistics { Browser = "Internet Explorer", Users = 5 , Text= "5%", Fill="#bfbfbf"},
       new Statistics { Browser = "Samsung Internet", Users = 7, Text= "7%", Fill="#ff944d"}
   };
   protected override void OnInitialized()
   {
       StatisticsDetails = StatisticsDetails.OrderBy(x => x.Users).ToList();
   }
}
