Add text hover axis labels

Hello everyone,

I have recently changed name to my x and y axis by doing this.
Now, I would like to display a description when the cursor is on the text. Does anyone know how to do that?

Thanks in advance

Here’s one way to do this: https://codepen.io/etpinard/pen/RJWPPd?editors=0010

Thanks for your example. However, that’s not what I was looking for.
What I am looking for is: displaying a description when the cursor is hover the x or y axis label (basically where I have changed my custom name). Do you know how to do that?
