Packageflare.scale
Interfacepublic interface IScaleMap
ImplementorsAxis, LegendRange

Interface used by classes which support mapping between spatial (x,y) coordinates and values in a data scale. For example, both an axis or legend range should provide this functionality.

Method detail
value()method
public function value(x:Number, y:Number, stayInBounds:Boolean = true):Object

Returns the scale value corresponding to a given coordinate.

Parameters
x:Number — the x-coordinate
 
y:Number — the y-coordinate
 
stayInBounds:Boolean (default = true) — if true, x,y values outside the current layout bounds will be snapped to the bounds. If false, the value lookup will attempt to extrapolate beyond the scale bounds. This value is true be default.

Returns
Object — the scale value corresponding to the given coordinate.
X()method 
public function X(val:Object):Number

Returns the x-coordinate corresponding to the given scale value

Parameters
val:Object — the scale value to lookup

Returns
Number — the x-coordinate at which that scale value is placed
Y()method 
public function Y(val:Object):Number

Returns the y-coordinate corresponding to the given scale value

Parameters
val:Object — the scale value to lookup

Returns
Number — the y-coordinate at which that scale value is placed
