CategoryAxis class Null safety

This class has the properties of the category axis.

Category axis displays text labels instead of numbers. When the string values are bound to x values, then the x-axis must be initialized with CategoryAxis.

Provides the options for Label placement, arrange by index and interval are used to customize the appearance.
