   <!--
   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]
   我参照 [官方示例](http://www.echartsjs.com/gallery/editor.html?c=dataset-series-layout-by) 中的代码，把 `source` 变成 `JSON` (试过对象数组和 `JSON`，都是可以渲染的) 以后，无法实现原先的改变行、列的效果
   
   
   
   
   ### 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]: Firefox 61.0.2
   + OS Version [操作系统类型和版本]: Windows 10
   
   
   
   
   
   ### Expected behaviour [期望结果]
   
   `source` 使用对象数组能够达到和示例二维数据表一样的可以置换行、列显示的效果
   
   
   ### 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] -->
   ```javascript
   option = {
     // 除了 dataset，其余部分和官网示例一样
     dataset: {
           dimensions: ['product', '2012', '2013', '2014', '2015'],
           source: [{"2012":"41.1","2013":"30.4","2014":"65.1","2015":"53.3","product":"Matcha Latte"},{"2012":"86.5","2013":"92.1","2014":"85.7","2015":"83.1","product":"Milk Tea"},{"2012":"24.1","2013":"67.2","2014":"79.5","2015":"86.4","product":"Cheese Cocoa"}]
       }
   }
   
   ```
