Quantitative

class Quantitative<DOMAIN>(accessor: Datum<DOMAIN>.() -> Double?, parentDimension: Quantitative<DOMAIN>?, init: Quantitative<DOMAIN>.() -> Unit) : ContinuousDimension<DOMAIN, Double?>

Quantitative is a Dimension that is used to manage continuous numeric values (as Double) It is build by giving an "accessor" lambda that returns a Double object from a given Datum of a <DOMAIN>.

Use the Chart.quantitative function to build a Quantitative dimension.

Examples:

val sizeDimension = quantitative( { domain.size } )
val speedDimension = quantitative( { domain.speed } )

Constructors

Quantitative

common

fun <DOMAIN> Quantitative(accessor: Datum<DOMAIN>.() -> Double?, parentDimension: Quantitative<DOMAIN>? = null, init: Quantitative<DOMAIN>.() -> Unit = {})

Functions

child

common

fun child(accessor: Datum<DOMAIN>.() -> Double?, init: Quantitative<DOMAIN>.() -> Unit = {}): Quantitative<DOMAIN>

Creates a child Dimension with the given accessor, use child dimensions to share axes with different properties.

invoke

common

operator fun invoke(datum: Datum<DOMAIN>): Double?

Calling Dimension(Datum) is the same as calling its accessor.

Properties

accessor

common

val accessor: Datum<DOMAIN>.() -> Double?

The "accessor" is the lambda used to transform a DOMAIN object into a VALUE.

formatter

common

open var formatter: Double?.() -> String?

The formatter for the VALUE this Dimension can generate.

isContinuous

common

val isContinuous: Boolean

Is this Dimension considered "continuous"?

isDiscrete

common

open override val isDiscrete: Boolean

Is this Dimension considered "discrete"?

name

common

var name: String?

The name of this Dimension, this name is used as the title of the Axis based on it.
