Rgraph show key when cliking line

Question

I want to display a tooltip when I click a line graph, along with the usual tooltip with the value. Is there any way to link from the canvas to the key area?!

Answer 1

Are you referring to the interactive key?

It's not a tooltip though - it highlights an entry on the key.

EDIT:

There's an example of a poly object that has been positioned to sit over the line(s) and which when clicked highlights the appropriate key entry. It wasn't simple to accomplish (lots of playing with coordinates) - but neither was it like trying to remember your wifes birthday when drunk:
