public sealed class CategoryKey : ISerializable, 
	IComparable<CategoryKey>, ICategoryKey, IComparable<ICategoryKey>, 
	ILibraryXmlSerializable

The CategoryKey type exposes the following members.

	Name	Description
	CategoryKey	Initializes a new instance of the CategoryKey class.

	Name	Description
	CompareTo	Compares the current object with another object of the same type.
	GetType	Gets the Type of the current instance. (Inherited from Object.)

Since categorical axes are hierarchical, a CategoryKey is made from the values of each level in the hierarchy. For instance, if an axis has an expression that nests an integer column within a string column, a category key would be defined by a string value and an integer.
