Discrete scales
Discrete scales map a domain, which can have discrete or continuous input, to a discrete range. This includes scales that map segments based on samples, subsets divided equally or using threshold values, one-to-one mappings, and mappings to spaces and points.
The following table lists the generator functions that create discrete scales:
|
Generator function |
Domain (input) |
