baseline | egenskap |
baseline:Number [skrivskyddad] | Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Implementering
public function get baseline():NumberchartDataProvider | egenskap |
chartDataProvider:Object [lässkyddad] | Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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).
Implementering
public function set chartDataProvider(value:Object):voiddisplayName | egenskap |
title | egenskap |
unitSize | egenskap |
unitSize:Number [skrivskyddad] | Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Implementering
public function get unitSize():NumberdataChanged | () | metod |
public function dataChanged():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Triggers events that inform the range object when the chart data has changed.
filterCache | () | metod |
public function filterCache(cache:Array, field:String, filteredString:String):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Filters a set of values of arbitrary type to a set of numbers that can be mapped.
Parametrar
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 | () | metod |
public function formatForScreen(value:Object):String| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Formats values for display in DataTips. Returns a user-readable string.
Parametrar
value:Object — The value to convert to a String.
|
String — The text of the DataTip.
|
getLabelEstimate | () | metod |
public function getLabelEstimate():AxisLabelSet| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
ReturnerarAxisLabelSet — An Array of AxisLabel objects.
|
getLabels | () | metod |
public function getLabels(minimumAxisLength:Number):AxisLabelSet| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
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.
|
invertTransform | () | metod |
public function invertTransform(value:Number):Object| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Maps a position along the axis back to a numeric data value.
Parametrar
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 | () | metod |
public function mapCache(cache:Array, field:String, convertedField:String, indexValues:Boolean = false):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Converts a set of values of arbitrary type to a set of numbers that can be transformed into screen coordinates.
Parametrar
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.
|
preferDropLabels | () | metod |
public function preferDropLabels():Boolean| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
public function reduceLabels(intervalStart:AxisLabel, intervalEnd:AxisLabel):AxisLabelSet| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
intervalStart:AxisLabel — The start of the interval where labels overlap.
| |
intervalEnd:AxisLabel — The end of the interval where labels overlap.
|
AxisLabelSet — A new label set that resolves the overlap by reducing
the number of labels.
|
registerDataTransform | () | metod |

| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.

| |
dimensionName:String — The name of the dimension.
|

| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
