How to overide the value displayed when the mouse is over with a text?

[Phil353556]

Hello,

When the pointer is over a circle like on the screenshot, how to overide the value (for example on the screenshot the value 3) by a word here "degraded" written for y lines (text)?

There is no decimal value only 1 , 2 to 8
and for each value there is a word mapped.
I hope I'm clear enough, sorry, and I don't know if it is possible or not.
Thanks for your help
Phil

Hi @Phil353556, when you need some customization, plz refer all options or API provided.
Answering your question, you can use tooltip.format.value option to update some tooltip value.
