   为了方便我们能够复现和修复 bug，请遵从下面的规范描述您的问题。
   -->
   
   
   ### One-line summary [问题简述]
   两个$.getJSON 用dataset找不到source，图形渲染不了，去掉一个getjson正常，使用内网映射到外网偶尔正常显示。
   报错： Uncaught TypeError: Cannot read property 'source' of undefined
   
   
   
   ### Version & Environment [版本及环境]
   + ECharts version [ECharts 版本]:4.1.0
   + Browser version [浏览器类型和版本]:chrome 66
   + OS Version [操作系统类型和版本]:mac 10.13
   
   
   
   
   
   ### Expected behaviour [期望结果]
   
   正常渲染数据
   
   
   
   ### ECharts option [ECharts配置项]
   <!-- Copy and paste your 'echarts option' here. -->
   <!-- [下方贴你的option，注意不要删掉下方 ```javascript 和 尾部的 ``` 字样。最好是我们能够直接运行的 
option。如何得到能运行的 option 参见上方的 guidelines for contributing] -->
