Counter of numbers passing through one point in Parallel Coordinate

Hey everyone!

The queston is: How create counter of numbers passing through one point in Parallel Coordinate (with ploty 2.0)?
My starting point was: https://plot.ly/python/parallel-coordinates-plot/

Idea - is create counter to determinate the number of value passing through one coordinate. (In this example - passing through x or z point in cyclinder material)
And also, how to create ltrend line? Which illustrate average value in dependence of selected section on any of the axes.

Thank you in advance
