echarts绘制地图

引入js

<script type="text/javascript" src="../e5script/new-js/jquery-1.11.2.min.js"></script>

<script type="text/javascript" src="../script/echarts/echarts-all.js"></script>

定义一个div

<!-- 为ECharts准备一个具备大小（宽高）的Dom -->
<div id="main" style="height:260px;"></div>

获取json数据

var time = 7;
$.ajax({
   url:"../xxxx/getXxx.do",//从后台获取json数据
   type:"POST",
   data:{time:time},
   dataType:"json",
   success:function(data){
      drawMap(time,data);//绘制地图
   },
   error:function(data){
      alert("获取数据异常");
   }
});

绘制地图

function drawMap(time,dataArr){
   var myChart = echarts.init(document.getElementById('main'));
   var option = {
      backgroundColor: '#1b1b1b',
      color: ['gold','aqua','lime'],

         text: xxx地图-全部站点-'+time+'天',
         x:'center',
         textStyle : {
            color: '#fff'
         }
      },
      tooltip : {

         formatter: '{b}'
      },

         orient: 'vertical',
         x:'left',
         data:['已授权', '...', '...', '...'],//自定义内容，可以通过函数获取自定义数组
         selectedMode: 'multiple',

         }
      },
      toolbox: {
         show : true,

               }]
            }
         },

         {...}
         }
      ]
   };

//遍历json对象，填充图表数据
   for (var k = 0; k < 4; k++) {
      for (var j = 0; j < dataArr.Data.ReprintMap.length; j++) {
         option.series[k+1].markLine.data[j] = [{

         }, {
            name: dataArr.Data.ReprintMap[j].smediaName,
            value: dataArr.Data.ReprintMap[j].sum
         }];
         option.series[k+1].markPoint.data[j] = {

            value: dataArr.Data.ReprintMap[j].sum
         };
      }
   }
   myChart.setOption(option);
}

 地图大致如下：
