PointScale<T> class

A point scale maps discrete domain values to points within a continuous range. Similar to band scale but with zero bandwidth.

Constructors

PointScale({List<T>? domain, List<double>? range, double padding = 0, double align = 0.5, bool round = false})

Creates a point scale with the given parameters.

Properties

align ↔ double

The alignment of points within the range (0 to 1).

getter/setter pair

bandwidth → double

The bandwidth is always 0 for point scales.

no setter

domain ↔ List<T>

The discrete domain values.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

padding ↔ double

The padding on the edges (0 to 1).

getter/setter pair

range ↔ List<double>

The continuous output range.

getter/setter pair

round ↔ bool

Whether to round output values.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

step → double

Returns the step between points.

no setter

Methods

call(T value) → double

Returns the position of the point for the given value.

copy() → PointScale<T>

Creates a copy of this scale.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.
