Unexpected formatter in tooltip header (category name)

[paulshatalov]

First of all - thank you guys for that incredible tool! Very configurable and easy to use. Really great!

And I want to help a bit by posting possible bug.

I use x axis formatter to add percentage and it seems it affects tooltips categories name.

Here is codepen: https://codepen.io/shatalovpaul/pen/EzqrOz

Actual for 3.7 and 3.6.12 at least

@paulshatalov Thanks for the compliment :)
Yeah, the formatter seems to be applied for both key and value of a tooltip. I will take a look soon, thanks for reporting.
