Provides the option to group the axis labels. You can customize the start, end value of a multi-level label, text, and level of the multi-level labels.
The start

values for the category axis need to be string type,
in the case of date-time or date-time category axes need to be date-time
and in the case of numeric or logarithmic axes needs to be double.
Defaults to null
