![]() | overflowEnabled : Boolean
Determines if items such as labels and other visual objects affect the
contentBounds property of the axis. | Axis | |
![]() | plotArea : IPlotArea
The plot area to which this axis is associated.
| Axis | |
![]() | reverse : Boolean
Sets the direction of the labels and other visual objects along the axis.
| Axis | |
snapToUnits : Boolean
If true, the labels, ticks, gridlines, and other objects will snap to
the nearest major or minor unit.
| TimeAxis | ||
![]() | title : String
The text that will appear next to the axis to indicate information
about the data that it displays.

public function TimeAxis()
Constructor.
calculateContentBounds | () | method |
protected override function calculateContentBounds():void
Determines the rectangular bounds where data may be drawn within this axis.
calculateMaximumLabelBounds | () | method |
protected function calculateMaximumLabelBounds(proposedMajorUnit:Number):Point
Parameters
proposedMajorUnit:Number |
Point |
drawAxis | () | method |
protected function drawAxis():void
Redraws the main axis.
drawObjectsOnMajorUnit | () | method |
protected function drawObjectsOnMajorUnit():void
Draws labels and ticks at the major unit positions.
localToValue | () | method |
public override function localToValue(position:Number):Object
Calculates the value of a data point along the axis based on a position.
Parametersposition:Number — The position in pixels used to determine the value
|
Object — The value on the axis at that position
|
resetScale | () | method |
protected function resetScale():void
If the minimum, maximum, major unit or minor unit have not been set by the user, these values must be generated by the axis. May be overridden to use custom scaling algorithms.
updateBounds | () | method |
public override function updateBounds(data:Array):void
Determines the axis scale based on the input data set. Seperating this function from the draw method optimizes processing time, and it allows the plot area to synchronize its axes.
Parametersdata:Array — The complete dataset that could be drawn on the axis.
|
updateScale | () | method |
public override function updateScale(data:Array):void
Determines the axis scale based on the input data set. Seperating this function from the draw method optimizes processing time, and it allows the plot area to synchronize its axes.
Parametersdata:Array — The complete dataset that could be drawn on the axis.
|
valueToLabel | () | method |
public override function valueToLabel(value:Object):String
Converts a value on the axis to formatted label text.
Parametersvalue:Object — the value of the item for which a label is needed
|
String — the formatted label text
|
valueToLocal | () | method |
public override function valueToLocal(value:Object):Number
Calculates the position of a data point along the axis.
Parametersvalue:Object — The data used to determine the position
|
Number — The display position in pixels on the axis
