   As you mentioned, you can use formatter in the label:
   - adding just a "%" would be easy:  "formatter": '{c}%'
   - if you want to limit the number of decimals, you have to use a callback:
   ```
   "formatter": function (params, ticket, callback) {
           return parseInt(params.value).toFixed(2)+' %';
       }
   
   ```
