Runtime Versions: | Flash Player 9, AIR 1.1 |
The DateTimeAxis chooses the most reasonable units
to mark the axis by examining the range between the minimum and maximum
values of the axis.
The Axis chooses the largest unit that generates
a reasonable number of labels for the given range.
You can restrict the set of units the chart considers,
or specify exactly which units it should use,
by setting the labelUnits
property.
You can specifiy the minimum and maximum values explicitly,
or let the axis automatically determine them by examining
the values being renderered in the chart.
By default, the DateTimeAxis chooses the smallest possible range
to contain all the values represented in the chart.
Optionally, you can request that the minimum and maximum values
be rounded to whole units
(milliseconds, seconds, minutes, hours, days, weeks, months, years)
by setting the autoAdjust
property to true
.
You can specify disabled days of a week and disabled ranges of dates in order to show only working days on the axis but not all days between minimum and maximum. It also filters data and shows only data corresponding to working days on the chart
MXML Syntax
The <mx:DateTimeAxis>
tag inherits all the properties
of its parent classes and adds the following properties:
<mx:DateTimeAxis Properties alignLabelsToUnits="true|false" dataUnits="milliseconds|seconds|minutes|hours|days|weeks|months|years" disabledDays="Array; No default" disabledRanges="Array; No default" displayLocalTime="false" interval="Number" labelUnits="milliseconds|seconds|minutes|hours|days|weeks|months|years" maximum="Date" minimum="Date" minorTickInterval="Number" minorTickUnits="milliseconds|seconds|minutes|hours|days|weeks|months|years" />
