[GitBox <gi...@apache.org>]

allran opened a new issue, #17301:
URL: https://github.com/apache/echarts/issues/17301

   ### What problem does this feature solve?
   
   The API like this:
   ```
   interface MarkAreaOption extends MarkerOption, MarkAreaStateOption, StatesOptionMixin<MarkAreaStateOption, StatesMixinBase> {
       mainType?: 'markArea';
       precision?: number;
       data?: (MarkArea1DDataItemOption | MarkArea2DDataItemOption)[];
   }
   ```
   
   This mean, I can use MarkArea1DDataItemOption to load data. But I don't find how to set it.  I use follow codes, and not running right:
   ```
   if (val_index == areaStartIndex) {
     x_d.push({xAxis: str1})
   } else {
     x_d.push([
       {xAxis: str1}, 
       {xAxis: str2}
     ])
   }
   ```
   
   Please tell me how to set it, thanks.
   
   ### What does the proposed API look like?
   
   If it is possible to complete the demo name ['**Distribution of Electricity**']，to use MarkArea1DDataItemOption and MarkArea2DDataItemOption load data, then the other person will kown how to use it, thanks.
