InteractiveCursor, how to convert Mouse position => OffsetX

[Rodolphe Billottet]

 Hi

I have a Chart diplaying financial indictors  (Xaxis is DateTime)

I want to dynamicaly add some InteractiveCursor (Only VerticalCurso)  in the Chart using the mouse a the exact place where I click (for instance with right click).

I tried the code below but there is a gap between mouse and  the InteractiveCursor X position

That seems to be the margine between the area and beginning of the axis/series.

I used a constant value '-44' to fix that gap, but it is a crapy solution.

How can I set correctly the OffsetX from the Mouse position ?

 

Code Snippet [C#]:

private void ChartAreaMouseRightButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
 var point = e.GetPosition(sender as ChartArea);
              
 currentCursor = new InteractiveCursor
 {
  OffsetX = point.X - 44,
  IsBindWithSegment = false,
  BindWithMouseMoveOnSegment = false,                                                                         
  HorizontalCursorVisibility = Visibility.Hidden,
  VerticalLabelVisibility = Visibility.Hidden,

...

}

ChartArea.InteractiveCursors.Add(currentCursor);

Hi Rodolphe,

Thanks for using the Syncfusion products.

We have analysed the reported requirement. You can achieve your requirement by applying the below code snippet.

Code snippet [C#]:

        private void ChartArea_MouseRightButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)

        {

            var point = e.GetPosition(sender as ChartArea);

 

            InteractiveCursor currentCursor = new InteractiveCursor

            {

                OffsetX = point.X - this.Chart1.Areas[0].AxesThickness.Left - ((sender as ChartArea).ElementMargin.Left *4),

                IsBindWithSegment = false,

                IsBindWithMouseMove = false,

                BindWithMouseMoveOnSegment = false,

                HorizontalCursorVisibility = Visibility.Hidden,

                VerticalLabelVisibility = Visibility.Hidden

            };

 

            Chart1.Areas[0].InteractiveCursors.Add(currentCursor);

        }

Please let us know if you require further assistance on this.

Thanks,
