chartDataProvider | 屬性 |
chartDataProvider:Object [唯寫] | 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The data provider assigned to the enclosing chart. Element types can choose to inherit the data provider from the enclosing chart if necessary, or allow developers to assign data providers specifically to the element. Not all elements are necessarily driven by a data provider.
實作
public function set chartDataProvider(value:Object):voiddataTransform | 屬性 |
dataTransform:mx.charts.chartClasses:DataTransform [唯寫] | 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The DataTransform object that the element uses to map between data and screen coordinates. This property is assigned by the enclosing chart.
實作
public function set dataTransform(value:mx.charts.chartClasses:DataTransform):voidlabelContainer | 屬性 |
labelContainer:Sprite [唯讀] | 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The DisplayObject that displays labels rendered by this element.
In most cases, labels displayed in the data area of a chart
are rendered on top of all elements
rather than interleaved with the data.
If an implementing Element has labels to display,
it can place them in a Sprite object
and return it as the value of the labelContainer property.
Enclosing charts will render labelContainers
from all enclosed elements and place them
in the data area above all other elements.
實作
public function get labelContainer():SpritechartStateChanged | () | 方法 |
public function chartStateChanged(oldState:uint, v:uint):void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | 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.
參數
oldState:uint — An integer representing the previous state.
| |
v:uint — An integer representing the new state.
|
claimStyles | () | 方法 |
public function claimStyles(styles:Array, firstAvailable:uint):uint| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Called by the chart to allow associated elements
to claim style selectors from its chartSeriesStyles Array.
Each chart has an associated set of selectors that are
implicitly assigned to contained elements that require them.
Implementing this function gives an element a chance to 'claim'
elements out of that set, as necessary.
An element that requires N style selectors claims the values
from styles[firstAvailable] to
styles[firstAvailable + N - 1].
參數
styles:Array — An Array of styles to claim.
| |
firstAvailable:uint — The first style selector in the Array to claim.
|
uint — The new value for firstAvailable
after claiming any styles (for example,
firstAvailable + N).
|
collectTransitions | () | 方法 |
public function collectTransitions(chartState:Number, transitions:Array):void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Called by the enclosing chart to collect any transitions a particular element might play when the chart changes state. The chart collects transitions from all elements and ensures that they play in parallel. It waits until all transitions have completed before advancing to another state. Implementors should append any necessary transitions to the transitions Array parameter.
參數
chartState:Number — The state at which the chart plays
the new transitions.
| |
transitions:Array — An Array of transition to add
to the chart's list of transitions to play.
|
describeData | () | 方法 |
public function describeData(dimension:String, requiredFields:uint):Array| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Called by the governing DataTransform to obtain a description
of the data represented by this IChartElement.
Implementors fill out and return an Array of
mx.charts.chartClasses.DataDescription objects
to guarantee that their data is correctly accounted for
by any axes that are autogenerating values
from the displayed data (such as minimum, maximum,
interval, and unitSize).
Most element types return an Array
containing a single DataDescription.
Aggregate elements, such as BarSet and ColumnSet,
might return multiple DataDescription instances
that describe the data displayed by their subelements.
When called, the implementor describes the data
along the axis indicated by the dimension argument.
This function might be called for each axis
supported by the containing chart.
參數
dimension:String — Determines the axis to get data descriptions of.
| |
requiredFields:uint — A bitfield that indicates which values
of the DataDescription object the particular axis cares about.
Implementors can optimize by only calculating the necessary fields.
|
Array — An Array containing the DataDescription instances that describe
the data that is displayed.

findDataPoints | () | 方法 |
public function findDataPoints(x:Number, y:Number, sensitivity2:Number):Array| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Returns a HitData object describing the nearest data point
to the coordinates passed to the method.
The x and y arguments
should be values in the Element's coordinate system.
This method aheres to the limits specified by the
sensitivity2 parameter
when looking for nearby data points.
參數
x:Number — The x coordinate relative to the ChartBase object.
| |
y:Number — The y coordinate relative to the ChartBase object.
| |
sensitivity2:Number — The maximum distance from the data point that the
x/y coordinate location can be.
|
Array — A HitData object describing the nearest data point
within sensitivity2 pixels.

mappingChanged | () | 方法 |
public function mappingChanged():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Indicates to the element that the data mapping of the associated axes has changed. Implementors should dispose of cached data and re-render appropriately. This function is called automatically by the associated DataTransform when necessary.
