Method | Defined By | ||
---|---|---|---|
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. | IEventDispatcher | ||
Called by the enclosing chart to indicate that the current state
of the chart has changed. | IChartElement | ||
Called by the chart to allow associated elements
to claim style selectors from its chartSeriesStyles Array. | IChartElement | ||
Called by the enclosing chart to collect any transitions
a particular element might play when the chart changes state. | IChartElement | ||
Converts a tuple of data values to an x-y coordinate on screen. | IChartElement2 | ||
Called by the governing DataTransform to obtain a description
of the data represented by this IChartElement. | IChartElement | ||
Dispatches an event into the event flow. | IEventDispatcher | ||
Returns a HitData object describing the nearest data point
to the coordinates passed to the method. | IChartElement | ||
Returns an array of HitData of the items of all the underlying
objects that implement IChartElement2 whose dataTips
are to be shown when showAllDataTips is set
to true on chart. | IChartElement2 | ||
Returns a rectangle that defines the area of the display object relative to the coordinate system
of the targetCoordinateSpace object. | IFlexDisplayObject | ||
Returns a rectangle that defines the boundary of the display object,
based on the coordinate system defined by the targetCoordinateSpace
parameter, excluding any strokes on shapes. | IFlexDisplayObject | ||
Converts the point object from the Stage (global) coordinates
to the display object's (local) coordinates. | IFlexDisplayObject | ||
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | IEventDispatcher | ||
Evaluates the bounding box of the display object to see if it overlaps or intersects with the
bounding box of the obj display object. | IFlexDisplayObject | ||
Evaluates the display object to see if it overlaps or intersects with the
point specified by the x and y parameters. | IFlexDisplayObject | ||
Converts a coordinate on screen to a tuple of data values. | IChartElement2 | ||
Converts the point object from the display object's (local) coordinates to the
Stage (global) coordinates. | IFlexDisplayObject | ||
Indicates to the element that the data mapping
of the associated axes has changed. | IChartElement | ||
Moves this object to the specified x and y coordinates. | IFlexDisplayObject | ||
Removes a listener from the EventDispatcher object. | IEventDispatcher | ||
Sets the actual size of this object. | IFlexDisplayObject | ||
Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type. | IEventDispatcher |
dataToLocal | () | method |
public function dataToLocal(... dataValues):Point
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Converts a tuple of data values to an x-y coordinate on screen. Call this function to transform data on to the screen using the same transform that the individual elements go through. For example, to create a custom highlight for a data region of a chart, you might use this function to determine the on-screen coordinates of the range of interest.
For Cartesian chartelements, you typically pass two values. The first value maps to the horizontal axis, and the second value maps to the vertical axis.
For polar charts, the first value maps to the angular axis, and the second maps to the radial axis.
Parameters
... dataValues — The data values to convert to coordinates.
|
Point — Coordinates that are relative to the chart.
|
getAllDataPoints | () | method |
public function getAllDataPoints():Array
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Returns an array of HitData of the items of all the underlying
objects that implement IChartElement2
whose dataTips
are to be shown when showAllDataTips
is set
to true
on chart.
Array — The HitData objects describing the data points
|
localToData | () | method |
public function localToData(pt:Point):Array
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Converts a coordinate on screen to a tuple of data values. Call this function to determine what data values a particular point on-screen represents.
Individual chart types determine how this transformation occurs. The point should be relative to the chart's coordinate space.
Parameters
pt:Point — The Point to convert.
|
Array — The tuple of data values.
