SymlogScale class

A symmetric log scale that handles both positive and negative values. Uses the bi-symmetric log transform: sign(x) * log(1 + |x / constant|)

Implemented types

• ContinuousScale<double, double>

Constructors

SymlogScale({List<double>? domain, List<double>? range, bool clamp = false, double constant = 1})

Creates a symlog scale with the given parameters.

Properties

clamp ↔ bool

Whether output values are clamped to the range.

getter/setter pair, override

constant ↔ double

The constant used in the symlog transform.

getter/setter pair

domain ↔ List<double>

The input domain.
