Classpublic class StackedAreaLayout
InheritanceStackedAreaLayout Inheritance Layout Inheritance Operator

Layout that consecutively places items on top of each other. The layout currently assumes that each column value is available as separate properties of individual DataSprites.


Public Properties
 PropertyDefined by
  columns : Array
Array containing the column names.
StackedAreaLayout
 Inheritedenabled : Boolean
Indicates if the operator is enabled or disabled.
Operator
 InheritedlayoutAnchor : Point
The layout anchor, used by some layout instances to place an initial item or determine a focal point.
Layout
 InheritedlayoutBounds : Rectangle
The layout bounds for the layout.
Layout
 InheritedlayoutRoot : DataSprite
The layout root, the root node for tree layouts.
Layout
 InheritedlayoutType : String = "null"

Layout
  normalize : Boolean
Flag indicating if the visualization should be normalized.
StackedAreaLayout
  orientation : String
The orientation of the layout.
StackedAreaLayout
  padding : Number
Value indicating the padding (as a percentage of the view) that should be reserved within the visualization.
StackedAreaLayout
 Inheritedparameters : Object
Sets parameter values for this operator.
Operator
  scale : QuantitativeScale
The scale used to layout the stacked values.
StackedAreaLayout
  threshold : Number
Threshold size value (in pixels) that at least one column width must surpass for a stack to remain visible.
StackedAreaLayout
 Inheritedvisualization : Visualization
The visualization processed by this operator.

Constructor detail
StackedAreaLayout()constructor
public function StackedAreaLayout(cols:Array = null, padding:Number = 0.05)

Creates a new StackedAreaLayout.

Parameters
cols:Array (default = null) — an ordered array of properties for the column values
 
padding:Number (default = 0.05) — percentage of space to leave as a padding margin for the stacked chart
Method detail
initializeAxes()method
protected function initializeAxes():void
