使用步骤：


  2. 引入echarts 插件文件到html页面中
  3. 准备一个具备大小的DOM容器

<div id="main" style="width: 600px;height:400px;"></div>
  1. 初始化echarts实例对象
var myChart = echarts.init(document.getElementById('main'));
  1. 指定配置项和数据(option)
var option = {    xAxis: {        type: 'category',        data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']    },    yAxis: {        type: 'value'    },    series: [{        data: [820, 932, 901, 934, 1290, 1330, 1320],        type: 'line'    }]};
  1. 将配置项设置给echarts实例对象
myChart.setOption(option);

        ]
      };
      // 把配置项给实例对象
      myChart.setOption(option);
    </script>
