Data returned when hover of UI Chart

Hello

Is there any way to return the points x and y values on the chart when I hover over the line with my mouse in the UI? At the moment it's returning this:

query2

In this example I'd like it to return 09:30:37, 3.729 for example

Well it would do if the topic wasn't so long.... Can you rename that before passing to the chart ?

That did the trick, thanks!
