-The new *plot*.**scale**(*name*) method exposes scales used by a particular plot. This method on returned plots takes the *name* of a scale and returns an object containing scale options that fully describe the scale’s behavior. The returned object represents the actual (or “materialized”) options used, including *scale*.domain, *scale*.range, *scale*.interpolate, *etc.* The *scale*.label, if any, is also returned; however, note that other axis properties are not currently exposed. The scale object is undefined if the associated plot has no scale with the given *name*, and throws an error if the *name* is invalid (*i.e.*, not one of the known scale names: *x*, *y*, *fx*, *fy*, *r*, *color*, or *opacity*). For example, given a plot:
