    I just added the following statement

    var n = flexChart.AxisX.ConvertBack(e.Position.X);

    to your example contained in Linemarkersample.xaml.cs (xamarin forms Flexchart 101 project for UWP)

    because I need to know the X position in data coordinates of the line marker

    but unfortunately it returns always 0

    of course the rest of your example works well

    the version of flexchart I am using is 3.2.20183.344

    Hi Sergio,

    This is a known issue with the FlexChart control, this was already escalated to the developers team with internal tracking Id : 358297. Will let you once we hear from them.

    Is the problem still pending?

    Hi Sergio,

    This function is just working on native Android / iOS after Axis is layout completely. But in XF, it is not supported at this time.

    Can you please give me the detailed purpose here ? What do you want to achieve with converted pixel coordinate? May be we can try to find a workaround for you (if possible).

    Hi Sergio,

    The example is not attached in the thread. Can you please re-attach the example for more clarity about the requirement.
