   这个与先前的 #12370, #8973, #10023, #12475 应该属于同一类问题，曾经在 #11973 中讨论过修复方法，不过似乎还未有定论和修复计划，暂时可以通过以下2种方式规避：
   1) 使用 [`tooltip.formatter`](https://echarts.apache.org/zh/option.html#tooltip.formatter)
   2) 使用 [`series.encode`](https://echarts.apache.org/zh/option.html#series-scatter.encode)，这个解决方案之前有提过PR，可以参考 ecomfe/echarts-examples#20。
   ```js
   encode: {
     value: 2
   }
   ```
   或者
   ```js
   encode: {
     tooltip: [2]
   }
   ```
