   ### One-line summary [问题简述]
   在vue项目中直接引入echarts.js文件，选择折线图模式，数据结构为:
   data: [
     {
        name: 'xxx',
        value: [
           'aaa',
           'bbb'
        ]
     }
     ...
   ]
   并且数据量达到一定时，会多出一条连接起点和终点的线。
   
   
   
   ### Version & Environment [版本及环境]
   + ECharts version 4.2.0:
   + Browser version chrome 69.0.3497.100:
