How to draw vertical Lines on Mouse left click event on Live Chart

[PabitraSwain-ltts]

How to reproduce?

I am trying to draw vertical lines on the mouse's left button click event on the chart for my WPF application. I am able to get the coordinate values from the chart and I tried with MouseLeftButtonDown() event but unfortunately not working.
I tried the below things on MouseLeftButtonDown() event:

var chart = (CartesianChart)sender;
var mousecoordinate = e.GetPiosition(chart);
var p = chart.ConvertToChartValues(mousecoordinate);

cartesianChart1.AxisX.Add( new Asix
{
Sections = new SectionCollection
   {
        new AxisSection{
             Value = p.X,
             Stroke = Brushes.Red,
             StrokeThickness =1
       }
    }
}
)

I tried this thing on Constructor but only one Red vertical line is coming but not on Mouse Click event even though I call this code multiple times.

I am using LiveChart.Geared.
