Description

Field is a collection of field names that are to be used to create values for a unique value renderer. When more than one field name is set, categories are generated based on all combinations of the unique values of all of the fields.

Remarks

Specifying more than one field is valuable when a feature is ambiguous in the categories defined by just one field. For example, in the United States "Jefferson" is a common county name. If you are making a map of the counties of the United States, you might choose to define your unique values symbolization based on two fields: county name and state name.
