Axis titles don't display on cartesian chart

Question

I use Adobe Flex Builder 3 to create charts for use in a
larger web application. Since moving from Flex Builder 2 to Flex
Builder 3, the axis titles are no longer being displayed.
In my mx:Application, I declare an mx:CartesianChart. I
dynamically add ColumnSeries to a ColumnSet based on the contents
of an XML file loaded using a URLRequest. I then add the ColumnSet
as the only element of the chart.series Array. The rest of the
chart (including the legend) displays correctly.
The axes are explicitly defined as part of the
mx:CartesianChart:
<mx:CartesianChart left="{legend.width}" top="30"
right="0" bottom="0" id="chart" dataProvider="{xmlDoc.elements()}"
showDataTips="true" dataTipFunction="formatDataTips">
<mx:verticalAxis>
<mx:LinearAxis id="vAx" autoAdjust="true" title="Dollars"
labelFunction="formatVerticalLabel"/>
</mx:verticalAxis>
<mx:horizontalAxis>
<mx:CategoryAxis id="hAx" categoryField="Year"
title="Year"/>
</mx:horizontalAxis>
<mx:horizontalAxisRenderers>
<mx:AxisRenderer axis="{hAx}" labelRotation="-60"/>
</mx:horizontalAxisRenderers>
</mx:CartesianChart>
Thanks in advance for your help.

I've isolated the issue, but I'm not sure if it's a bug or if
something I'm doing wrong. The following simplified version of my
chart application doesn't display the axis titles:
[code]
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Legend dataProvider="{chart}" left="0" top="25"
id="legend"/>
<mx:CartesianChart left="{legend.width}" top="30"
right="0" bottom="0" id="chart">
<mx:verticalAxis>
<mx:LinearAxis title="Dollars"/>
</mx:verticalAxis>
<mx:horizontalAxis>
<mx:CategoryAxis title="Year"/>
</mx:horizontalAxis>
</mx:CartesianChart>
</mx:Application>
[/code]
The following version does:
[code]
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Legend dataProvider="{chart}" left="0" top="25"
id="legend"/>
<mx:CartesianChart left="{0}" top="30" right="0"
bottom="0" id="chart">
<mx:verticalAxis>
<mx:LinearAxis title="Dollars"/>
</mx:verticalAxis>
<mx:horizontalAxis>
<mx:CategoryAxis title="Year"/>
</mx:horizontalAxis>
</mx:CartesianChart>
</mx:Application>
[/code]
The only difference is the left definition for
mx:CartesianChart. When it's defined in terms of the width of the
legend, the axis titles disappear. Is there another way that I
should be displaying my chart using the full span of the
application?
Thanks again for your help.
