Implements IScale

A scale that can be used to convert Dates to layout space.

AbstractScale
 Inheritedinvalidated : Boolean
[read-only] Indicates that the scale should recalculate it's minimum and maximum values and layouts the next time either layoutToValue or valueToLayout is called.

Public Methods
 MethodDefined By
 Inherited
invalidate():void
Marks this IScale as needing its minValue and maxValue recomputed.
AbstractScale
  
layoutToValue(layout:*, invert:Boolean = false, clamp:Boolean = false):*
Converts a layout position to a value that would arise in the space defined by the implementing class.
DateTimeScale
  
validate():void
DateTimeScale
  
valueToLayout(value:*, invert:Boolean = false, clamp:Boolean = false):*
Converts a value to a position in layout space.

Dispatched when the data in the becomes invalid and the new min, max, sum, and average need to be computed.AbstractScale
Method Detail
computeSum()method
override protected function computeSum():*

Returns
*
layoutToValue()method 
public function layoutToValue(layout:*, invert:Boolean = false, clamp:Boolean = false):*

Converts a layout position to a value that would arise in the space defined by the implementing class. For example, LinearScale converts a layout position to a Number between minValue and maxValue, whether or not that Number is actually present within the dataProvider. CategoricalScale, on the other hand, will only convert layout positions to values found within the dataProvider.

Parameters

layout:* — layout position to translate into a value.
 
invert:Boolean (default = false)
 
clamp:Boolean (default = false)

Returns
*
validate()method 
override public function validate():void

valueToLayout()method 
public function valueToLayout(value:*, invert:Boolean = false, clamp:Boolean = false):*

Converts a value to a position in layout space.

Parameters

value:* — The value to be converted into layout space.
 
invert:Boolean (default = false) — Whether the minValue translates to minLayout (false) or to maxLayout (true).
 
clamp:Boolean (default = false)

Returns
*
