highcharts动态获取数据生成图表问题

  动态获取数据说白点就是从后台传值到前台，前台把这些值赋值给x轴与y轴（这里指的是你X轴与Y轴都是变化的数据，如果你的X轴是固定的，像时间等等的那就另说）。
  柱状图的动态传值：

//获取后台数据var x = [];//X轴var y = [];//Y轴var xtext = [];//X轴TEXTvar 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+")");//转换数据				            for(var key in json.rows){json.rows[key].y = json.rows[key].money; //给Y轴赋值xtext = json.rows[key].name;//给X轴TEXT赋值json.rows[key].color= color[key];}//新建图表     chart = new Highcharts.Chart({  chart: {  renderTo: 'container',           //图表放置的容器，关联DIV#id   type: 'column',                    //柱状图 reflow:true                    //自适应div的大小  },  title: {  text: '分类采购额'            //图表标题   },  xAxis: {                            //X轴标签   categories:[xtext]},  yAxis: {                            //设置Y轴  title: {  text: '采购额 (元)'  }  },credits:{                          //右下角文本不显示enabled: false},tooltip:{                        //鼠标移动到图形上时显示的提示框      headerFormat: '{series.name}：<span style="font-size:12px"><b>{point.key}</b></span><table>',pointFormat: '<tr><td>采购额： </td>' +'<td style="padding:0"><b>{point.y:.1f} ￥</b></td></tr>',footerFormat: '</table>',shared: true,useHTML: true}, series:[{name:"商品类别"}]   }),  chart.series[0].setData(json.rows);//数据填充到highcharts上面},
}						        error:function(e){}});

 

//action层调用从数据库中查询出来的方法，获取数据。Dao层从数据库中查询，与service层调用Dao层方法

 public void showInfoList() throws IOException{      List list = null;List _list = new ArrayList();try {list = (ArrayList<DocProSto>)inOrderListService.CountAll();  //调用查询方法          if(list.size()>0){for(DocProSto pro:list){           //遍历后台传值Map<String,Object> map = new HashMap<String,Object>();map.put("money",pro.getMoney() );map.put("name", pro.getProduct().getTprosort().getName());map.put("number",pro.getNumber());_list.add(map);    }}} catch (Exception e) {e.printStackTrace();}Map<String, Object> jsonMap = new HashMap<String, Object>();//定义map  jsonMap.put("rows", _list);//rows键 存放每页记录 list  result =  JSON.toJSONStringWithDateFormat(jsonMap,"yyyy-MM-dd");//格式化resultresponse.setContentType("text/html;charset=utf-8");PrintWriter out = response.getWriter();out.print(result);out.flush();out.close();}
