LineChart with unknown amount and name of elements

Question

Hi!
I want to create a LineChart. This charts displays a changing
number over a period of time.
<?xml version="1.0" encoding="utf-8"?>
<root>
<poll>
<id>1</id>
<answerIDs>
<id>a1</id>
<id>a2</id>
</answerIDs>
<resultsByDate>
<entry date="03/01/2007">
<1><results>15</results></1>
<2><results>18</results></2>
</entry>
<entry date="03/02/2007">
<1><results>25</results></1>
<2><results>8</results></2>
</entry>
<entry date="03/03/2007">
<1><results>45</results></1>
<2><results>38</results></2>
</entry>
</resultsByDate>
</poll>
</root>
<mx:LineChart id="chart"
dataProvider="{service.lastResult.root.poll.resultsByDate.entry}"
>
<mx:horizontalAxis>
<mx:CategoryAxis categoryField="date" />
</mx:horizontalAxis>
<mx:horizontalAxisRenderer>
<mx:AxisRenderer labelRotation="45" />
</mx:horizontalAxisRenderer>
<mx:series>
<mx:LineSeries displayName="1" xField="date"
yField="results" />
<mx:LineSeries displayName="2" xField="date"
yField="results" />
</mx:series>
</mx:LineChart>
It only works when I don't use <results> in the XML and
set the yField to "1" or "2".
Later In the application I don't know the amount and name of
the elements (1,2,44,4564, ..), so I will use AS for that:
var ls:LineSeries = new LineSeries();
chart.series = [ls]; // associate the array
var answers:Array = ["1", "2"];
for (var i:uint = 0; i < 2; i++)
trace(i);
ls = new LineSeries();
ls.displayName = answers
.toString()
ls.xField = 'date';
ls.yField = 'results';
chart.series = ls;
This code works, but only without 'results'.
Maybe can someone help me? I sit not possible to have nested
objects as provider for xField and yField?

By using a temporary table instead of a permanent.SET @query =
'SELECT * INTO #NewPivotTable
FROM
SELECT productId,_year,amount
FROM Products
)t
PIVOT (SUM(amount) FOR _year
IN ('+@years+')) AS pvt; SELECT * FROM #NewPivotTable '
EXECUTE (@query)
