How to get coordinates of x and y in WPF Chart (SfChart)?

This article explains how to get the coordinates of x and y axes using the MouseDownClick event in WPF Chart (SfChart). In this example, the Mouse.GetPosition(ChartName) gets the x and y coordinates of the window and then converts the coordinates point to a value using the PointToValue function.

XAML

<!--The co-ordinates of x and y were shown on MouseDown Event-->
<Syncfusion:SfChart Name="ScatterChart" MouseDown="ScatterChart_MouseDoubleClick" Width="700" Height="500">

C#

private void ScatterChart_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{   
  Point position = new Point { X = e.GetPosition(ScatterChart).X - ScatterChart.SeriesClipRect.Left, Y =       e.GetPosition(ScatterChart).Y - ScatterChart.SeriesClipRect.Top};
  //PointToValue converts window coordinates to chart X,Y coordinates
  double xValue = this.ScatterChart.PointToValue(this.ScatterChart.PrimaryAxis, position);
  double yValue = this.ScatterChart.PointToValue(this.ScatterChart.SecondaryAxis, position);
  MessageBox.Show("X: " + xValue + "\n" + "Y: " + yValue);
}
