Hi!

I have 3 series of spline type. When doing mouse over at some point, I need to get the 3 "Y" values corresponding to that "X", and then send them. Currently I'm only getting 1 of these 3 values (the one closest to the mouse pointer). This is what I tried:

The second doubt is the following. I have to graph those 3 values in 3 different "gauge" graphics that are already drawn. I want to obtain the instance of said graphs in the following way:

But I get an error of "$(...).Highcharts is not a function". As I understand it, this is the way to obtain the instance of these graphics.

Thanks!
