最近做个项目,项目经理想做一个统计报表,在网上查看些资料就选用Highchars 这里和大家分享下使用心得。 

  重点说明此代码是针对一个报表显示多个项对比显示。 

        直接贴代码:web端                

     <script type="text/javascript" src="js/jquery/jquery-1.7.2.js"></script>
      <script type="text/javascript" src="js/highcharts/highcharts.js"></script>
      <script type="text/javascript">    
           $(document).ready(function() {
                    var options = {
                          chart: {
                                       renderTo: ‘container‘, //DIV容器ID
                                       type: ‘column‘//报表类型
                                     },
                            //报表名称
                            title:{
                                     text:‘测试‘
                                    },  
                              / /补充说明
                      subtitle: {
                                      text: ‘报表说明‘

                                     },
                          yAxis: {
                                       min: 0,
                                       title: {
                                               text: ‘单位(mm)‘
                                               }
                                        },
                                //x轴显示内容
                              xAxis: {
                                    categories: [ ]
                                          },
                                / /数据来源(多个对比的)        
                                 series: [{},{},{},{}]
                                };
                               //json url 地址这里我使用的servlet
                                var url =  "http://127.0.0.1:8080/servlet/JsonServlet";
                                $.getJSON(url,function(data) { 
                                       var i,len=data.length;         
                                        for( i=0;i<len;i++){

                                          //赋值 series
                                          options.series[i].data = data[i].list;    
                                          options.series[i].name = data[i].name;

                                           //对报表X轴显示名称赋值
                                           options.xAxis.categories[i]=data[i].year;
                                      }    
                                   var chart = new Highcharts.Chart(options);
                             });
                      });  

  </script>
  <body>
    <div id="container"></div>     
  </body>

 

后台servlet doget() 方法内容:

    response.setCharacterEncoding("UTF-8");
    response.setContentType("text/html");  
    JSONArray members = new JSONArray();
    PrintWriter out= response.getWriter();
    try {
     for(int i=1;i<5;i++){

   //构建JSON 对象
      JSONObject member = new JSONObject();

     //构建series所需参数
      member.put("name", "张飞"+i); //对应series.name
      JSONArray list = new JSONArray();//对应series.data
      for(int k=1;k<5;k++){
       list.put(k*100);
      }
      member.put("year", (2012 + i));//对应Y轴显示
      member.put("list", list);
      member.put("color", "#FF0022");//如需要可以设置柱状图颜色
      members.put(member);
     }
   
   out.write(members.toString());
   
  } catch (JSONException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
      
  out.flush();
  out.close();
