chartDataProvider | proprietà |
chartDataProvider:Object [sola scrittura] | Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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).

displayName:String| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
The name of the axis. If set, Flex uses this name to format DataTip controls.

unitSize:Number [sola lettura] | Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.

public function dataChanged():void| Versione linguaggio: | ActionScript 3.0 |

| Versioni runtime: | Flash Player 9, AIR 1.1 |
Triggers events that inform the range object when the chart data has changed.
describeData | () | metodo |
protected function describeData(requiredFields:uint):Array| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Parametri
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 of BoundedValue objects containing the DataDescription instances that describe
the data that is displayed.

registerDataTransform | () | metodo |
public function registerDataTransform(transform:mx.charts.chartClasses:DataTransform, dimensionName:String):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Parametri
transform:mx.charts.chartClasses:DataTransform — The DataTransform to register.

dimensionName:String — The name of the dimension.

unregisterDataTransform | () | metodo |
public function unregisterDataTransform(transform:mx.charts.chartClasses:DataTransform):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Parametri
transform:mx.charts.chartClasses:DataTransform — The DataTransform to unregister.
