CategoryBaseUnit

Specifies the baseUnit type of the category axis.

The possible values are:

• BaseUnit—Sets the base time interval for the axis labels.
• "auto"—Automatically determines the base unit by the minimum difference between subsequent categories.
• "fit"—Adjusts the categoryAxis.baseUnitStep and base unit so that the number of categories does not exceed categoryAxis.maxDateGroups, and uses the series.aggregate function to aggregate data based on the selected base unit.
