   请注意，所有 issue 必须由 https://ecomfe.github.io/echarts-issue-helper/?lang=zh-cn 创建，不然将会被直接关闭。
   Issues 中不要问「如何使用 ECharts 实现……功能」的问题，相关问题请到 SegmentFault 或 Stack Overflow 提问，详见上面的链接。

   建议ECharts图例和悬停提示只是部分html内容，在某些专业领域对此很注重。
   比如：
   空气质量的PM<sub>2.5</sub>中的2.5就是下标。
   化学里面的离子Na<sup>+</sup>中的+就是上标。
   长度单位10m<sup>2</sub>中的2是上标。
