   > If you want to get the data of a specific dimension, you can use it as follows, with the [doc](https://www.echartsjs.com/option.html#series-bar.label.formatter):
   > 
   > ```js
   > series: [
   >         {
   >             type: 'bar',
   >             label: {
   >                 show: true,
   >                 formatter: '{b}: {@2015}'
   >             }
   >         }]
   > ```
   I am not only want to get a specific dimension, I want to use a function to transform and calculate it, which is specified in API doc. And it doesn't have the correct behavior.
