Strange behavior of axis methods
Hello. I am a bit confused by how the axis methods ValueToCoord and CoordToValue work. I have LC v.2015.12.18.4001 (6.5.6 ?) for WinForms. I created Chart (size in pixels is about 600*300) with axes X(min: -1, max: 1) and Y(min: -1, max: 1). When I converted X zero value to coordinate I got value 33...

Crossing of 2 lines
Hello.
I have some lines (objects of PointLineSeries or FreeFormSeries..) and would like to determine where they cross each other. And I would draw some "marker" in this place and get X,Y coordinate of this place.
Does Lightning Chart have any API to help me with it?
Thank you.

Whether it is possible to make so that in case of change of width of border the distance between lines didn't change?

Maybe you could try if you can achieve your goal with series.CustomLinePointColoringAndShaping event? In there, you would have to set transparent colors for two coordinates.

That is, if there are points in a 3 series with values 10,20,30 that Y was to 30, but not the to 10+20+30, and we see only the third series?
