xml - Flex Stacked ColumnChart not showing up -

i have following xml structure:

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

i want represented in column chart stacked bars. first column comprise of columns stacked on each other values 21,22,25 , 26 corresponding sunday. length of values might change each time dataprovider updated. wrote code like:

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;      

but graph coming out empty. did go wrong?

below code may you:-
