플렉스 스택 ColumnChart에이

Question

을 표시되지 나는 다음과 같은 XML 구조가 있습니다

<root> 
    <day name="Sun" values="21,22,25,26"/> 
    <day name="Mon" values="27,20,22,25"/> 
</root> 

나는 그것이 스택 막대 세로 막 대형 차트에 표현하고자합니다. 첫 번째 열은 일요일에 해당하는 21,22,25,26의 값으로 서로 쌓인 열로 구성됩니다. 값의 길이는 dataprovider가 갱신 될 때마다 변경 될 수 있습니다. 그래서 내가 좋아하는 코드를 작성 :

var columnChart:ColumnChart = new ColumnChart(); 
columnchart.type="stacked"; 
var yAxisData:String = "@values"; 
var xAxisData:String = "@name"; 
var dp:XMLListCollection = new XMLListCollection(xmlFile.day); 
columnchart.dataProvider = dp; 

var valueLength:int = dp[0][yAxisData].toString().split(",").length; 
for(var count:int = 0;count<valueLength;count++){ 
var bSeries:ColumnSeries = new ColumnSeries(); 
bSeries.dataProvider = dataProvider; 
bSeries.xField = xAxisData; 
bSeries.yField = yAxisData+"["+count+"]"; 
columnchart.series.push(bSeries); 
} 
var hAxis:CategoryAxis = new CategoryAxis(); 
hAxis.dataProvider = dp; 
hAxis.categoryField = xAxisData ; 
CartesianChart(columnchart).horizontalAxis = hAxis;  

그러나 그래프는 비어있는 것으로 밝혀오고있다. 나는 어디로 잘못 갔는가?
