How to customize the trackball appearance in WPF Chart?

This article explains how to change the Trackball's default appearance. It has been shown by default with the corresponding Y- axis value. But here you are going to learn a way to display the trackball content with its corresponding X- axis value.  This can be achieved with the help of the TrackBallLabelTemplate in the WPF Chart Series as shown in the following code snippet


                <DataTemplate x:Key="labelTemplate">
                    <Border CornerRadius="2" Background="Violet">
                        <TextBlock Foreground="White" Margin="5" Text="{Binding Item.Name}"/>
                ItemsSource="{Binding Data}" 
                TrackBallLabelTemplate="{StaticResource labelTemplate}"
                YBindingPath="Height" >
                <syncfusion:ChartTrackBallBehavior />



The following screenshot displays a chart with customized trackball content.
