class anychart.scales.Linear Improve this Doc

Extends: anychart.scales.ScatterBase

The Linear class contains methods for configuring Linear scale.
Represents simple linear scale that transforms values from domain [a, b] to domain [0, 1]. Note that a can be greater than b. The only condition for the scale is that a != b.
Note: To create instance use anychart.scales#linear method.
