| Classe | public class CartesianTransform |
| Herança | CartesianTransform  DataTransform EventDispatcher Object |
When using charts in your applications, you typically will not need to interact with the CartesianTransform object. Transforms are created automatically by the built-in chart types and used by the series contained within so that they can transform data into rendering coordinates.

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 2-dimensional value in data space.
| CartesianTransform | ||
|
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 | |
|
Returns the string representation of the specified object.

transformCache(cache:Array, xField:String, xConvertedField:String, yField:String, yConvertedField:String):void
Maps a set of numeric values representing data to screen coordinates.
| CartesianTransform | ||
|
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.

public function CartesianTransform()
Constructor.
| invertTransform | () | método |
public override function invertTransform(... values):Array
Transforms x and y coordinates relative to the DataTransform coordinate system into a 2-dimensional value in data space.
Parâmetros
... values |
Array — An Array containing the transformed values.
|
| transformCache | () | método |
public override function transformCache(cache:Array, xField:String, xConvertedField:String, yField:String, yConvertedField:String):void
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.
Parâmetros
cache:Array — An array of objects containing the data values
in their fields.
This is also where this function stores the converted numeric values.
|
|
xField:String — The field where the data values for the x axis are stored.
|
|
xConvertedField:String — The field where the mapped x screen coordinate
is stored.
|
|
yField:String — The field where the data values for the y axis are stored.
|
|
yConvertedField:String — The field where the mapped y screen coordinate
is stored.
|
| HORIZONTAL_AXIS | Constante |
public static const HORIZONTAL_AXIS:String = "h"
A String representing the horizontal axis.
| VERTICAL_AXIS | Constante |
public static const VERTICAL_AXIS:String = "v"
A String representing the vertical axis.
