How to remove the blended color effect in multiple line series of SfChart?

This article explains how to remove the blended color effect in multiple line series within WPF SfChart. By extending the LineSeries class and setting the RenderOptions.EdgeMode to Aliased for rendered visual in the CreateSegments method, you can achieve a clearer line representation.

XAML:

<chart:SfChart.Series>
          <local:LineSeriesExt XBindingPath="SportName" YBindingPath="Interest" 
                                          Label="Series 1" ItemsSource="{Binding Data}" Interior="Blue"/>
           <local:LineSeriesExt XBindingPath="SportName" YBindingPath="Interest" 
                                          Label="Series 2" ItemsSource="{Binding Data}" Interior="Yellow"/>
</chart:SfChart.Series>

C#:

public class LineSeriesExt : LineSeries
{
        public override void CreateSegments()
        {
            base.CreateSegments();
 
            foreach (Syncfusion.UI.Xaml.Charts. LineSegment segment in Segments)
            {
                RenderOptions.SetEdgeMode((segment.GetRenderedVisual() as Line), EdgeMode.Aliased);
            }
        }
}

Note: To avoid this workaround, you can use FastLineBitmapSeries, because it removes the blended color effect by default.

Output:

With blended effect:

Without blended effect:
