How to sort pie chart points in Blazor Charts?

This article explains how to sort pie chart points.

Sorting accumulation chart points

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

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

The below code example 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();
   }
}
