Maurice Amsellem commented on FLEX-32919:
-----------------------------------------
The DateTimeAxis needs to span several months for the bug to occur.
Here is a sample app (adapted from mx:DateTimeAxis doc)
<?xml version="1.0"?>
<!-- Simple example to demonstrate the DateTimeAxis class. -->
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009";
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
public var stockDataAC:ArrayCollection = new ArrayCollection([
{date: "2012/11/1", value: 10},
{date: "2012/12/1", value: 25},
{date: "2013/1/1", value:30},
{date: "2013/2/1", value: 42},
{date: "2013/3/1", value: 48},
]);
]]>
</fx:Script>
<mx:LineChart id="mychart" height="100%" width="100%"
dataProvider="{stockDataAC}">
<mx:horizontalAxis>
<mx:DateTimeAxis/>
</mx:horizontalAxis>
<mx:series>
<mx:LineSeries yField="value" xField="date" displayName="Test"/>
</mx:series>
</mx:LineChart>
</s:Application>
Attached screenshots shows the result with SDK 4.1 (axis labels in wrong order)
and in SDK 4.9 (axis labels is correct order)
> Issue is with the mx.charts.DateTimeAxis class

> Key: FLEX-32919
> URL: https://issues.apache.org/jira/browse/FLEX-32919
> Project: Apache Flex
> Issue Type: Bug
> Components: Charts
> Affects Versions: Adobe Flex SDK Previous
> Environment: Affected OS(s): All OS Platforms
> Affected OS(s): All OS Platforms
> Language Found: English
> Reporter: Adobe JIRA
>
> Steps to reproduce:
> 1. Please add DateTimeAxis in any chart component and add min and max range
> to the month like min is nov,2010 and max is jan 2011 and set the direction
> as normal
> 2. Check the labels. It will reverted in the descending order but the
> behavior should be like it should show in ascending order.
> 3. The code which has issue is as follows inside the buildLabelCache() method
> of the class. For non inverted option as well in the else part is also
> treated as inverted one.
> if(direction == "inverted")
> labelCache.push(new AxisLabel(
> 1 - (dTime - computedMinimum) / r, new
> Date(dTime),
> lfunc(labelDate, previousValue, this)));
> else
> labelCache.push(new AxisLabel(
> 1 - (dTime - computedMinimum) / r, new
> Date(dTime),
> lfunc(labelDate, previousValue, this)));
> So the correction should be in the else part the code should be like the
> following.
> labelCache.push(new AxisLabel(
> (dTime - computedMinimum) / r, new Date(dTime),
> lfunc(labelDate, previousValue, this)));
>
> Actual Results: Labels are displayed in the descending order
>
>
> Expected Results: Labels should come as ascending for the dates.
>
>
> Workaround (if any): If we can fix the code and rebuild the flex which right
> now i am not knowing how to do it but i will figure out soon as i am seeing
> ant build scripts and i have a experience with the same.
