The most recent set of AxisLabel objects
generated to represent this axis.
This property is null if the axis

labelFunction:Function| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | Flash Player 9, AIR 1.1 |
Called to format axis values for display as labels.
A labelFunction has the following signature:
function function_name(labelValue:Object, previousValue:Object, axis:IAxis):String { ... }
If you know the types of the data your function will be formatting,
you can specify an explicit type for the labelValue
and previousValue parameters.

The maximum value where a label should be placed. After computing an adjusted minimum value, many axis types expand the range of the axis further to make room for additional rendering artifacts in the chart, such as labels and borders. This value represents the maximum value in the chart before it is adjusted for these artifacts. Typically axes generate labels to make sure this value is labeled, rather than the adjusted maximum of the axis.

| Versões de runtime: | Flash Player 9, AIR 1.1 |
The minimum value where a label should be placed. After computing an adjusted minimum value, many axis types expand the range of the axis further to make room for additional rendering artifacts in the chart, such as labels and borders. This value represents the minimum value in the chart before it is adjusted for these artifacts. Typically axes will generate labels to make sure this value is labeled, rather than the adjusted minimum of the axis.

| |
maxValue:Number — The computed maximum value.
|
buildLabelCache | () | método |
protected function buildLabelCache():Boolean| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | Flash Player 9, AIR 1.1 |
Populates the labelCache property with labels representing the current
values of the axis. Subclasses must implement this function. This function is called
many times, so you should check to see if the labelCache property
is null before performing any calculations.
Boolean — true if the labels were regenerated.
|
buildMinorTickCache | () | método |
protected function buildMinorTickCache():Array| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | Flash Player 9, AIR 1.1 |

Subclasses must implement this function. This function is called automatically
by the NumericAxis. You should access the minorTicks property
instead of calling this function directly.
Array — An Array of positions from 0 to 1 that represent points between the axis
minimum and maximum values where minor tick marks are rendered.
|
filterCache | () | método |
public function filterCache(cache:Array, field:String, filteredField:String):void| Versão da linguagem: | ActionScript 3.0 |

Parâmetros
cache:Array — An Array of objects where converted values
are read from and stored.

|
getLabelEstimate | () | método |
public function getLabelEstimate():AxisLabelSet| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | 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.
RetornaAxisLabelSet — An Array of AxisLabel objects.
|
getLabels | () | método |
public function getLabels(minimumAxisLength:Number):AxisLabelSet| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | 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.
Parâmetros
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.
|
guardMinMax | () | método |
protected function guardMinMax(min:Number, max:Number):Array| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | Flash Player 9, AIR 1.1 |
Protects the range against invalid values for this axis type. This function is called during the update cycle of the axis to guarantee that invalid ranges are not generated. Subclasses can override this class and define logic that is appropriate to their axis type.
Parâmetros
min:Number — The computed minimum value.
| |
max:Number — The computed maximum value.
|
Array — null if no adjustment is necessary, or an Array containing the adjusted
values of the form [min,max].

| Versão de produto: | Flex 3 |
| Versões de runtime: | Flash Player 9, AIR 1.1 |
Invalidates the cached labels and tick marks that represent this axis's values. Derived classes should call this function whenever values used in the calculation of labels and tick marks change.

public function invertTransform(value:Number):Object| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | Flash Player 9, AIR 1.1 |

public function preferDropLabels():Boolean| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | Flash Player 9, AIR 1.1 |
