baseline | 속성 |
baseline:Number [읽기 전용] | 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
The baseline position for the axis. Some series, such as ColumnSeries or AreaSeries, use this value to define the base of a filled region when no minimum value is specified.
구현
public function get baseline():NumberchartDataProvider | 속성 |
chartDataProvider:Object [쓰기 전용] | 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
The data provider assigned to the enclosing chart.
Axis types that are data provider-based can choose to inherit
the data provider associated with the enclosing chart.
If an axis is shared among multiple charts,
the value of this property is undefined
(most likely it will be the last data provider assigned
to one of the associated charts).
구현
public function set chartDataProvider(value:Object):voiddisplayName | 속성 |
title | 속성 |
unitSize | 속성 |
unitSize:Number [읽기 전용] | 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
The size of one unit of data as represented by this axis.
This value is used by various series types to help in rendering.
The ColumnSeries class, for example, uses this value
to determine how wide columns should be rendered.
Different axis types return different values,
sometimes dependent on the data being represented.
The DateTimeAxis class, for example, might return the number
of milliseconds in a day, or a year, depending on the data
that is rendered in the chart.
Because this value is dependant on collecting the represented data,
custom series cannot assume this value is accurate in their
updateData() or updateMapping() methods.
구현
public function get unitSize():NumberdataChanged | () | 메서드 |
public function dataChanged():void| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Triggers events that inform the range object when the chart data has changed.
filterCache | () | 메서드 |
public function filterCache(cache:Array, field:String, filteredString:String):void| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Filters a set of values of arbitrary type to a set of numbers that can be mapped.
매개 변수
cache:Array — An Array of objects where converted values
are read from and stored.
| |
field:String — The field of the objects in the cache Array
containing the pre-filtered values.
| |
filteredString:String — The field of the objects in the cache Array
where filtered values should be stored.

formatForScreen | () | 메서드 |
getLabelEstimate | () | 메서드 |
public function getLabelEstimate():AxisLabelSet| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Determines the range to estimate what the axis labels should be.
The axis almost immediately calls the getLabels() method
to get the real values.
The axis uses the estimated values to adjust chart margins,
so any difference between the estimated labels and actual labels
(returned from the getLabels() method) results in scaling
the labels to fit.
An axis need only return the minimum and maximum labels when returning an estimate. If the label set is fairly static, without depending on the size of the axis being rendered on screen, an axis can return the entire label set from this function, and mark the estimate as accurate.
반환값AxisLabelSet — An Array of AxisLabel objects.
|
getLabels | () | 메서드 |
public function getLabels(minimumAxisLength:Number):AxisLabelSet| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Gets the labels text that is rendered. When Flex calls this method, the axis has already determined the minimum length of the label.
매개 변수
minimumAxisLength:Number — The minimum length of the axis, in pixels.
The axis can be longer than this value, but not shorter.
|
AxisLabelSet — An array of AxisLabel objects.
|

public function invertTransform(value:Number):Object| 언어 버전: | ActionScript 3.0 |

| 런타임 버전: | Flash Player 9, AIR 1.1 |
Maps a position along the axis back to a numeric data value.
매개 변수
value:Number — The bound of the axis.
This parameter should be between 0 and 1,
with 0 representing the minimum bound of the axis, and 1 the maximum.
|
Object — An object containing the transformed value.
|
mapCache | () | 메서드 |
public function mapCache(cache:Array, field:String, convertedField:String, indexValues:Boolean = false):void| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |

매개 변수
cache:Array — An Array of objects where converted values
are read from and stored.
| |
field:String — The field of the objects in the cache Array
containing the pre-converted values.
| |
convertedField:String — The field of the objects in the cache Array
where converted values should be stored.
| |
indexValues:Boolean (default = false)true if the values being mapped
are index values, and false if they are natural data values.

public function preferDropLabels():Boolean| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Determines how the axis handles overlapping labels.
Typically, numeric ranges return true,
while discrete value-based ranges do not.
You can can override this property by setting it directly on the axis.
Boolean — true if labels can be dropped without loss of data;
otherwise, false.
|
reduceLabels | () | 메서드 |
public function reduceLabels(intervalStart:AxisLabel, intervalEnd:AxisLabel):AxisLabelSet| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Invoked when an AxisRenderer is unable to cleanly render the labels without overlap, and would like the Axis object to reduce the set of labels. The method is passed the two labels that are overlapping.
매개 변수
intervalStart:AxisLabel — The start of the interval where labels overlap.
| |
intervalEnd:AxisLabel — The end of the interval where labels overlap.
