   Yeah, it's a known issue. The reason is that data on the category axis will be assigned the category as its name. And data with the same name will be selected together. 
   
   Currently the solution is give each data a unique name:
   ```ts
   let uniqueId = ''
   map[key].push({
             name: 'id_' + uniqueId++,
             value: [i, keys.length - 1 - j, f ? f.statistic : 0]
            });
   ```
