highcharts動態獲取數據生成圖表問題

  動態獲取數聽說白點就是從後臺傳值到前臺，前臺把這些值賦值給x軸與y軸（這裏指的是你X軸與Y軸都是變化的數據，若是你的X軸是固定的，像時間等等的那就另說）。
  柱狀圖的動態傳值：

//獲取後臺數據
             var x = [];//X軸
             var y = [];//Y軸
	     var xtext = [];//X軸TEXT
	     var color = ["#FFB6C1","#DC143C","#C71585","#D8BFD8","#8B008B","#4B0082","#6A5ACD","#0000FF","#B0C4DE","#1E90FF","#00CED1","#228B22"];
           $.ajax({
		        type:'post',
		        url:'${pageContext.request.contextPath}/InOrder!showInfoList.do',
		        success:function(data){
				            var json = eval("("+data+")");//轉換數據				            
				            for(var key in json.rows){
				                json.rows[key].y = json.rows[key].money; //給Y軸賦值
				                xtext = json.rows[key].name;//給X軸TEXT賦值
				                json.rows[key].color= color[key];
				            }
				            
				     //新建圖表     
		                    chart = new Highcharts.Chart({  
				                chart: {  
				                    renderTo: 'container',           //圖表放置的容器，關聯DIV#id   
				                    type: 'column',                    //柱狀圖 
				                    reflow:true                    //自適應div的大小  
				                },

				                    categories:[xtext]
				                },  
				                yAxis: {                            //設置Y軸  
				                    title: {
