   Hi @VictorCazanave 
   
   Perhaps you can try to filter out data with `null` siblings and use a `bar` series to draw it. for example
   
   ```js
   series: [{
     type: 'bar'
     data: data.filter((val, idx) => {
         return idx > 0 && idx < data.length - 1 
                         && data[idx - 1] == null && data[idx + 1] == null
               ? val  // Display bar if value has null siblings
               : '-'    // Not display bar for other values
     })
   ]}
   ```
