Discrete

class Discrete<DOMAIN, VALUE>(accessor: Datum<DOMAIN>.() -> VALUE, init: Discrete<DOMAIN, VALUE>.() -> Unit) : DiscreteDimension<DOMAIN, VALUE>

Discrete is a Dimension that is used to manage discrete values. It is build by giving an "accessor" lambda that returns a discrete <VALUE> object from a given Datum of a <DOMAIN>.

Use the Chart.discrete function to build a Discrete dimension.

Examples:

val fruitsDimension = discrete( { domain.fruitName } )
val weatherDimension = discrete( { domain.weatherType } )
val students = discrete( { domain } )
val indexDimension = discrete( { indexInData } )

Constructors

Discrete

common

fun <DOMAIN, VALUE> Discrete(accessor: Datum<DOMAIN>.() -> VALUE, init: Discrete<DOMAIN, VALUE>.() -> Unit = {})

Functions

invoke

common

operator fun invoke(datum: Datum<DOMAIN>): VALUE

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

Properties

accessor

common

val accessor: Datum<DOMAIN>.() -> VALUE

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

formatter

common

open var formatter: VALUE.() -> 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.
