Line chart hover

Hi there, I am trying to set the hover options in a line chart. What I want is that when I hover the line of the chart, not only the "y" value is shown but also the correct name from the legend (There are 26 lines in it)   I hope someone is able to answer this question Please note im not a proffesional developer!

Hi Quinten,

This question is for a pie chart but should be the same.
