Sure, put it into an XMLListCollection. I *THINK* that will get you out
of the namespace problems, because you then use the XLC API, instead of
e4x expressions. Example:
private var _xlcTrackpointCollection:XMLListCollection;
//instance scope var
...
var myXML2:XMLList = dataSet.descendants("Trackpoint"); //the XMLList
_xlcTrackpointCollection = new XMLListCollection(myXML2); //wrap the
XMLList in the collection
<mx:LineChart ... dataProvider="{_xlcTrackpointCollection }">
Now, I have not worked with charting much at all, so I won't be much
help there.

Subject: [flexcoders] Re: Problems walking XML file with E4X
Argh, now I'm trying to graph this stuff and I can't figure out how to
access the info. Maybe I should jsut throw it into an array
collection? I saw a post that you did that said put it into an
XMLListCollection...
This is what I got:
<mx:LineChart height="100%" width="100%" dataProvider="{myXML3}">
<mx:series>
<mx:LineSeries yField="HeartRateBpm" xField="Time"
dataProvider="{myXML3}"/>
</mx:series>
<mx:verticalAxis>
<mx:LinearAxis id="chartLA" />
</mx:verticalAxis>
<mx:horizontalAxis>
<mx:DateTimeAxis />
</mx:horizontalAxis>
</mx:LineChart>
