The AxisBase class serves as a base class
for the various axis types supported in Flex.

Flex components inherit the following properties
from the AxisBase class:
<mx:tagname
displayName="No default"
title="No default"
>
chartDataProvider:Object [write-only]
| Language Version: | ActionScript 3.0 |
| Runtime Versions: | 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).
Implementation public function set chartDataProvider(value:Object):voiddisplayName:String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The name of the axis.
If set, Flex uses this name to format DataTip controls.
Implementation public function get displayName():String public function set displayName(value:String):voidtitle:String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The text for the title displayed along the axis.
Implementation public function get title():String public function set title(value:String):voidunitSize:Number [read-only]
| Language Version: | ActionScript 3.0 |
| Runtime Versions: | 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.

Constructor.
public function dataChanged():void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Triggers events that inform the range object
when the chart data has changed.
protected function describeData(requiredFields:uint):Array| Language Version: | ActionScript 3.0 |
| Runtime Versions: | 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.
Parameters
| 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.
|
Returns | Array — An Array of BoundedValue objects containing the DataDescription instances that describe
the data that is displayed.

public function registerDataTransform(transform:mx.charts.chartClasses:DataTransform, dimensionName:String):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Each DataTransform that makes use of an axis
registers itself with that axis.
The axis is responsible for informing the transform
when its relevant values have changed.
It should also request values from the transform
when it wants to autogenerate minimum and maximum values.
Parameters
public function unregisterDataTransform(transform:mx.charts.chartClasses:DataTransform):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Each DataTransform that makes use of an axis
registers itself with that axis.
The axis is responsible for informing the transform
when its relevant values have changed.
It should also request values from the transform
when it wants to autogenerate minimum and maximum values.
Parameters
EventDispatcher
