  Hi,

  We have been using the line marker to draw an intersect on a line graph that will return the all the series data where they match the x value of where the line is drawn.

  We have used HitTestInfo to query this information but have found that this selects the closest DataPoint rather than using the X value of wherever the line marker is drawn.
  
  We’ve also tried to use the x,y coordindates to get this info, but we can only see a way of getting the x Value via the HitTest, which again uses closest DataPoint rather than current location.

  Could you tell us if its possible to just return the x Value of wherever the LineMarker is? If you could also provide an example that would be super helpful.

  Thanks,

  Reece

  Hello,

  To get the X and Y value of wherever Line Marker is, you may use the x and y properties of LineMarker class. Please refer to the sample provided.

  API reference:

  x-value:
