OrdinalScale

OrdinalScale[{cat1, cat2, ..., catn}] represents a set of ordered categories cati with order cat1 < cat2 < … < catn.

• OrdinalScale[{cat1, ..., catn}, {val1, ..., valn}] associates the category cati with the numeric value vali.
• OrdinalScale[<|cat1 -> val1, ..., catn -> valn|>] also associates the category cati with the numeric value vali.
• OrdinalScale[{cat1, ..., catn}, vals, {lab1, ..., labn}] displays the category cati as the corresponding labi when used as a label in plots.

Examples

OrdinalScale[{"Low", "Medium", "High"}]

OrdinalScale[<|"Small" -> 1, "Medium" -> 2, "Large" -> 3|>]
