minimum, maximum,
and interval values from the charting data
to fit all of the chart elements on the screen.
You can also explicitly set specific values for these properties.
The auto-determination of range values works as follows:
autoAdjust and baseAtZero properties
are set to true, Flex makes the following adjustments:
minimum property to zero.maximum property to zero.autoAdjust property is set to true,
Flex adjusts values of the minimum and maximum
properties by rounding them up or down.minimum and
maximum properties accordingly.minimum and maximum values,
and adjusts their values accordingly.

addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener
receives notification of an event.
| EventDispatcher | |
|
Triggers events that inform the range object
when the chart data has changed.
| AxisBase | |
|
Dispatches an event into the event flow.
| EventDispatcher | |
|
Filters a set of values of arbitrary type
to a set of numbers that can be mapped.
| NumericAxis | |
|
Formats values for display in DataTips.
| NumericAxis | |
|
Determines the range to estimate what the axis labels should be.
| NumericAxis | |
|
Gets the labels text that is rendered.
| NumericAxis | |
|
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event.
| EventDispatcher | |
|
Indicates whether an object has a specified property defined.
| Object | |
|
Maps a position along the axis back to a numeric data value.
| NumericAxis | |
|
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter.
| Object | |
|
Converts a set of values of arbitrary type
to a set of numbers that can be transformed into screen coordinates.
| NumericAxis | |
|
Determines how the axis handles overlapping labels.
| NumericAxis | |
|
Indicates whether the specified property exists and is enumerable.
| Object | |
|
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.
| NumericAxis | |
|
Each DataTransform that makes use of an axis
registers itself with that axis.
| AxisBase | |
|
Removes a listener from the EventDispatcher object.
| EventDispatcher | |
|
Sets the availability of a dynamic property for loop operations.
| Object | |
|
Returns the string representation of the specified object.
| Object | |
|
Maps a set of values from data space to screen space.
| NumericAxis | |
|
Each DataTransform that makes use of an axis
registers itself with that axis.
| AxisBase | |
|
Updates the chart.
| NumericAxis | |
|
Returns the primitive value of the specified object.
| Object | |
|
Checks whether an event listener is registered with this EventDispatcher object or any of
its ancestors for the specified event type.
| EventDispatcher | |
| interval | property |
interval:Number [read-write]
Specifies the numeric difference between label values along the axis.
Flex calculates the interval if this property
is set to NaN.
The default value is NaN.
public function get interval():Number
public function set interval(value:Number):void
| maximum | property |
maximum:Number [read-write]
Specifies the maximum value for an axis label.
If you set the autoAdjust property to true,
Flex calculates this value.
If NaN, Flex determines the maximum value
from the data in the chart.
The default value is NaN.
public function get maximum():Number
public function set maximum(value:Number):void
| maximumLabelPrecision | property |
maximumLabelPrecision:Number [read-write] Specifies the maximum number of decimal places for representing fractional values on the labels generated by this axis. By default, the axis autogenerates this value from the labels themselves. A value of 0 rounds to the nearest integer value, while a value of 2 rounds to the nearest 1/100th of a value.
public function get maximumLabelPrecision():Number
public function set maximumLabelPrecision(value:Number):void
| minimum | property |
minimum:Number [read-write]
Specifies the minimum value for an axis label.
If NaN, Flex determines the minimum value
from the data in the chart.
The default value is NaN.
public function get minimum():Number
public function set minimum(value:Number):void
| minorInterval | property |
minorInterval:Number [read-write]
Specifies the numeric difference between minor tick marks along the axis.
Flex calculates the difference if this property
is set to NaN.
public function get minorInterval():Number
public function set minorInterval(value:Number):void
| LinearAxis | () | Constructor |
public function LinearAxis()
Constructor.
