  I have an application with 2 flex charts, each share the same horizontal axis data but have different vertical axis data sets.
  
  I want to have a line marker which tracks with the mouse, one on chart, and a line marker on the other has its position updated to keep in sync with the first linemarker

  Using an earlier version of the flexchart component, I was able to raise and event when the mouse moved on one chart that effectively updated the linemarker position in the other chart. (I was setting the X and Y values of the linemarker)

  with the latest version of the component, I set the horizontal and vertical values of the second line marker (and they seem to update), but the actual position of the linemarker doesn’t change.
  
  I already invalidate the flexchart after updating the linemarker position.
  
  any ideas?
  
  thanks
  
  Richard

  Hello,

  I was able to replicate the issue and it seems to be a bug. I have escalated this problem to the concerned development team [Internal Tracking Id: 341412] and will update you when the issue will get fixed.

  Thank you.

  thanks for the quick reply
  
  any thoughts on a possible work around other than going back to the previous version of the component?
  
  thanks

  Hi Richard,

  Although there is no direct work around for this but one possible way is by inheriting FlexChart class and exposing a method to perform mouse move programmatically.

  class FlexChartEx : FlexChart
  {
    public void PerformMouseMove(MouseEventArgs eArgs)
    {
      this.OnMouseMove(eArgs);
    }
  }
  

  Please refer to the attached sample for an example.

  Thanks and Regards,

  Basant
