Property Detail

axis

property
axis:IAxis

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The axis object associated with this renderer. This property is managed by the enclosing chart, and should not be explicitly set.



Implementation
    public function get axis():IAxis
    public function set axis(value:IAxis):void

gutters

property 
gutters:Rectangle

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The distance between the axisRenderer and the sides of the surrounding chart. This property is assigned automatically by the chart, and should not be assigned directly.



Implementation
    public function get gutters():Rectangle
    public function set gutters(value:Rectangle):void

heightLimit

property 
heightLimit:Number

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The maximum amount of space, in pixels, that an axis renderer will take from a chart. Axis Renderers by default will take up as much space in the chart as necessary to render all of their labels at full size. If heightLimit is set, an AxisRenderer will resort to reducing the labels in size in order to guarantee the total size of the axis is less than heightLimit.



Implementation
    public function get heightLimit():Number
    public function set heightLimit(value:Number):void

horizontal

property 
horizontal:Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

true if the axis renderer is being used as a horizontal axis. This property is managed by the enclosing CartesianChart, and should not be set directly.



Implementation
    public function get horizontal():Boolean
    public function set horizontal(value:Boolean):void

minorTicks

property 
minorTicks:Array  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Contains an array that specifies where Flex draws the minor tick marks along the axis. Each array element contains a value between 0 and 1.



Implementation
    public function get minorTicks():Array

otherAxes

property 
otherAxes:Array  [write-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

An Array of axes.



Implementation
    public function set otherAxes(value:Array):void

placement

property 
placement:String

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The side of the chart the axisRenderer will appear on. Legal values are "left" and "right" for vertical axis renderers and "top" and "bottom" for horizontal axis renderers. By default, primary axes are placed on the left and top, and secondary axes are placed on the right and bottom. CartesianCharts automatically guarantee that secondary axes are placed opposite primary axes; if you explicitly place a primary vertical axis on the right, for example, the secondary vertical axis is swapped to the left.



Implementation
    public function get placement():String
    public function set placement(value:String):void

ticks

property 
ticks:Array  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Contains an array that specifies where Flex draws the tick marks along the axis. Each array element contains a value between 0 and 1.



Implementation
    public function get ticks():Array
Method Detail

adjustGutters

()method
public function adjustGutters(workingGutters:Rectangle, adjustable:Object):Rectangle

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Adjusts its layout to accomodate the gutters passed in. This method is called by the enclosing chart to determine the size of the gutters and the corresponding data area. This method provides the AxisRenderer with an opportunity to calculate layout based on the new gutters, and to adjust them if necessary. If a given gutter is adjustable, an axis renderer can optionally adjust the gutters inward (make the gutter larger) but not outward (make the gutter smaller).

Parameters

workingGutters:Rectangle — Defines the gutters to adjust.
 
adjustable:Object — Consists of four Boolean properties (left=true/false, top=true/false, right=true/false, and bottom=true/false) that indicate whether the axis renderer can optionally adjust each of the gutters further.

Returns
Rectangle — A rectangle that defines the dimensions of the gutters, including the adjustments.

chartStateChanged

()method 
public function chartStateChanged(oldState:uint, v:uint):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Called by the enclosing chart to indicate that the current state of the chart has changed. Implementing elements should respond to this method in order to synchronize changes to the data displayed by the element.

Parameters

oldState:uint — An integer representing the previous state.
 
v:uint — An integer representing the new state.
