Class | public class PolarTransform |
Inheritance | PolarTransform DataTransform EventDispatcher Object |
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
You typically do not need to interact with the PolarTransform object. Transforms are created automatically by the built-in chart types and are used by the series contained within to transform data into rendering coordinates.
Property | Defined By | ||
---|---|---|---|
axes : Object [read-only]
The set of axes associated with this transform. | DataTransform | ||
constructor : Object
A reference to the class object or constructor function for a given object instance. | Object | ||
elements : Array
The elements that are associated with this transform. | DataTransform | ||
origin : Point [read-only]
The origin of the polar transform. | PolarTransform | ||
prototype : Object [static]
A reference to the prototype object of a class or function object. | Object | ||
radius : Number [read-only]
The radius used by the transform to convert data units
to polar coordinates. | PolarTransform |
Method | Defined By | ||
---|---|---|---|
Constructor. | PolarTransform | ||
addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener
receives notification of an event. | EventDispatcher | ||
Informs the DataTransform that some of the underlying data
being represented on the chart has changed. | DataTransform | ||
Collects important displayed values for all elements
associated with this data transform. | DataTransform | ||
Dispatches an event into the event flow. | EventDispatcher | ||
Retrieves the axis instance responsible for transforming
the data dimension specified by the dimension parameter. | DataTransform | ||
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | EventDispatcher | ||
Indicates whether an object has a specified property defined. | Object | ||
Transforms x and y coordinates relative to the DataTransform
coordinate system into a two-dimensional value in data space. | DataTransform | ||
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | ||
Indicates whether the specified property exists and is enumerable. | Object | ||
Removes a listener from the EventDispatcher object. | EventDispatcher | ||
Assigns an axis instance to a particular dimension of the transform. | DataTransform | ||
Sets the availability of a dynamic property for loop operations. | Object | ||
Sets the width and height that the PolarTransform uses
when calculating origin and radius. | PolarTransform | ||
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | ||
Returns the string representation of the specified object. | Object | ||
transformCache(cache:Array, aField:String, aConvertedField:String, rField:String, rConvertedField:String):void [override]
Maps a set of numeric values representing data to screen coordinates. | PolarTransform | ||
Returns the primitive value of the specified object. | Object | ||
Checks whether an event listener is registered with this EventDispatcher object or any of
its ancestors for the specified event type. | EventDispatcher |
Constant | Defined By | ||

ANGULAR_AXIS : String = "a" [static]
A string representing the angular axis. | PolarTransform | ||
RADIAL_AXIS : String = "r" [static]
A string representing the radial axis. | PolarTransform |
origin | property |
origin:Point
[read-only] Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
The origin of the polar transform. This point is used by associated series to convert data units to screen coordinates.
Implementation
public function get origin():Point
radius | property |
radius:Number
[read-only] Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
The radius used by the transform to convert data units to polar coordinates.
Implementation
public function get radius():Number
PolarTransform | () | Constructor |
public function PolarTransform()
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Constructor.
setSize | () | method |
public function setSize(width:Number, height:Number):void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Sets the width and height that the PolarTransform uses when calculating origin and radius. The containing chart calls this method. You should not generally call this method directly.
Parameters
width:Number — The width, in pixels, of the PolarTransform.
| |
height:Number — The height, in pixels, of the PolarTransform.
|
transformCache | () | method |
override public function transformCache(cache:Array, aField:String, aConvertedField:String, rField:String, rConvertedField:String):void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Maps a set of numeric values representing data to screen coordinates.
This method assumes the values are all numbers,
so any non-numeric values must have been previously converted
with the mapCache()
method.
Parameters
cache:Array — An array of objects containing the data values
in their fields. This is also where this function
will store the converted numeric values.
| |
aField:String — The field where the data values for the x axis
can be found.
| |
aConvertedField:String — The field where the mapped x screen coordinate
will be stored.
| |
rField:String — The field where the data values for the y axis
can be found.
| |
rConvertedField:String — The field where the mapped y screen coordinate
will be stored.

ANGULAR_AXIS | Constant |
public static const ANGULAR_AXIS:String = "a"
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
A string representing the angular axis.
RADIAL_AXIS | Constant |
public static const RADIAL_AXIS:String = "r"
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
A string representing the radial axis.
