Customize the marker for specific data point

We can customize the marker for specific data point with custom template for LineSparkline and AreaSparkline, in order to customize the marker we need to inherit the MarkerTemplateSelector class and override the SelectTemplate method.

<Syncfusion:SfLineSparkline x:Name="sparkline" MarkerVisibility="Visible" ItemsSource="{Binding UsersList}" YBindingPath="NoOfUsers" >


		<local:CustomMarkersTemplateSelector MarkerHeight="10" MarkerWidth="10"/>


public class CustomMarkersTemplateSelector : MarkerTemplateSelector


	protected override DataTemplate SelectTemplate(double x, double y)


		if (y == MaximumY)    


			DataTemplate markerTemplate = Application.Current.Resources["markerTemplate"] as DataTemplate;

			return markerTemplate;



			return base.SelectTemplate(x, y);
