How to set up highcharts (x-area labels on hover)?

Question

JavaScript

I've been tinkering with the plugin for the second day and have not set up only the last one...
How can I set up the change in the color of the names along the X axis when hovering over the chart?
The picture shows an example (number 19 along the X axis).
Somewhere I saw the setting of this parameter, but I lost it and can't find it
