NSScale

NSScale is a common scale interpolator. It transformes numerical or ordinal values using a range and a domain. NSScale offers several scales as class side methods. The code of the scales are inspired from https://github.com/d3/d3-scale

Responsibility: act as a scale interpolator for numerical and ordinal values.

Collaborators: NSScale depends on a number of Pharo packages, including Colors, Random-Core. The scales are intensively used by Roassal

Variables:

• range: contains an array of two elements. The range variable defines the range of the scaled value.
• VARIABLE2:

Example:

s := NSScale linear.
s range: { 5 . 10 }.
s scale: 0. "=> 5"
s scale: 0.5. "=> 7.5"
s scale: 1. "=> 10"

s := NSScale linear.
s domain: { -1 . 1 }.
s range: { 5 . 10 }.
s scale: 0.5

s := NSScale linear.
s range: { Color white . Color black }.
s scale: 0.5  "=> Color gray"
