ScalePoint<X> class final Point scales

Point scales are a variant of band scales with the bandwidth fixed to zero.

Point scales are typically used for scatterplots with an ordinal or categorical dimension.

ScalePoint({List<X>? domain, List<num>? range}): Constructs a new point scale with the specified domain and range, no padding, no rounding and center alignment. If domain is not specified, it defaults to the empty domain. If range is not specified, it defaults to the unit range [0, 1].

align ↔ num: How any leftover unused space in the range is distributed.
getter/setter pair
bandwidth → num: Returns zero.
no setter
domain ↔ List<X>: The scale's domain that specifies the input values.

hashCode → int: The hash code for this object.
no setterinherited
implicit ↔ bool: Whether or not the scale currently infers domain implicitly from usage.

padding ↔ num: The amount of blank space, in terms of multiples of the step, to reserve before the first point and after the last point.
getter/setter pair
range ↔ List<num>: The scale's range that specifies the output values.

round ↔ bool: Whether or not the scale currently rounds the edges of the bands.

runtimeType → Type: A representation of the runtime type of the object.

step → num: Returns the distance between adjacent points.

unknown ↔ num?: The output value of the scale for unknown input values.

call(X? x) → num?: Given a value in the input domain, returns the corresponding point derived from the output range.

copy() → ScalePoint<X>: Returns an exact copy of this scale.

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

rangeRound(List<num> range) → void: Sets the scale’s range to the specified two-element list of numbers while also enabling rounding.
toString() → String: A string representation of this object.
