Method | Defined By | ||
---|---|---|---|
chartStateChanged(oldState:uint, v:uint):void
Called by the enclosing chart to indicate that the current state
of the chart has changed. | IChartElement | ||
claimStyles(styles:Array, firstAvailable:uint):uint
Called by the chart to allow associated elements
to claim style selectors from its chartSeriesStyles Array. | IChartElement | ||
collectTransitions(chartState:Number, transitions:Array):void
Called by the enclosing chart to collect any transitions
a particular element might play when the chart changes state. | IChartElement | ||
dataToLocal(... dataValues):Point
Converts a tuple of data values to an x-y coordinate on screen. | IChartElement2 | ||
describeData(dimension:String, requiredFields:uint):Array
Called by the governing DataTransform to obtain a description
of the data represented by this IChartElement. | IChartElement | ||
findDataPoints(x:Number, y:Number, sensitivity2:Number):Array
Returns a HitData object describing the nearest data point
to the coordinates passed to the method. | IChartElement | ||
getAllDataPoints():Array
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 | ||
getBounds(targetCoordinateSpace:DisplayObject):Rectangle | IFlexDisplayObject | ||
getRect(targetCoordinateSpace:DisplayObject):Rectangle | IFlexDisplayObject | ||

hitTestObject(obj:DisplayObject):Boolean | IFlexDisplayObject | ||
hitTestPoint(x:Number, y:Number, shapeFlag:Boolean = false):Boolean | IFlexDisplayObject | ||
localToData(pt:Point):Array
Converts a coordinate on screen to a tuple of data values. | IChartElement2 | ||
localToGlobal(point:Point):Point | IFlexDisplayObject | ||
mappingChanged():void
Indicates to the element that the data mapping
of the associated axes has changed. | IChartElement | ||
move(x:Number, y:Number):void
Moves this object to the specified x and y coordinates. | IFlexDisplayObject | ||
setActualSize(newWidth:Number, newHeight:Number):void
Sets the actual size of this object. | IFlexDisplayObject |
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.
