I implemented a parallel coordinates chart in highchart and already activated hovering.

However, most of the times there is more than one serie lines on the same point (= value of a category) For instance, in the example linked above, there could be multiple lines on shoes=Adidas). When hovering this point, I would like to examine all series lines going through this point and not only the one on the top, e.g. I want to see, how Adidas shoes correlate with other categories (or at least see, wether there is some correlation).

I guess, basically I am looking for something like hover all lines in this point at once or even better: switch between all lines while hovering this point. Any idea how I could do this?

An answer about how to do it has been given by Paweł Fus on stackoverflow: https://stackoverflow.com/questions/51144076/highcharts-parallel-coordinates-hover-highlight-all-series-through-point/51154589#51154589.
