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 setterinherited
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 setterinherited
step → double
Returns the step between points.

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.
