LogScale class

A logarithmic scale for data that spans multiple orders of magnitude.

Logarithmic scales are useful for visualizing data with exponential growth.

Inheritance

• Object
• Scale<double>
• LogScale

Constructors

LogScale({required (double, double) domain, required (double, double) range, double base = 10, bool clamp = false})

Properties

base → double

The logarithm base (default: 10).

final

clamp → bool

Whether to clamp output values to the range.

final

domain → (double, double)

The input domain (data space) as (min, max).

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

isInverted → bool

Whether this scale is inverted (range end < range start).

no setter, inherited

range → (double, double)

The output range (screen space) as (start, end).

no setter, override

rangeExtent → double

The length of the range.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

copyWithDomain(double min, double max) → Scale<double>

Creates a copy of this scale with a new domain.

override

copyWithRange(double start, double end) → Scale<double>

Creates a copy of this scale with a new range.

override

invert(double value) → double

Inverse mapping from range value to domain value.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

scale(double value) → double

Maps a domain value to a range value.

override

tickFormatter({int? precision}) → String Function(double)

Returns a tick formatter function for this scale.

override

ticks({int? count}) → List<double>

Returns nicely-rounded tick values for this scale.

override

toString() → String

A string representation of this object.
