scale
Constructor for the scale type. Scales are used to transform data coordinates into scaled coordinates. Commonly, data is displayed with a linear scale, i.e., the entire data is just scaled uniformly. However, in order to visualize large ranges, it is often desirable to use logarithmic scaling or other scales that improve the readability of the data.
transform : function
Transformation from data coordinates to scaled coordinates.
Note that the transformation function does not need to worry about absolute
scaling and offset. As an example, the transformation function for the linear
scale is just x => x and not x => a * x + b or similar and the logarithmic
scale uses x => calc.log(x).
inverse : function
A precise inverse of the transform should be given here to enable the
conversion of scaled coordinates back to data coordinates.
name : str default: ""
Name of the scale. Built-in scales are sometimes identified by their name, e.g., when a suitable tick locator needs to be selected automatically.
identity : int | float default: 0
An identity value which can be used to find an initial axis range when no limits or plots are given. Scales like logarithmic scales that are only defined for positive values should set this to 1.
..args : any
Additional data to store in the scale.
