    }

  
  ],
  "responsive": {
    "rules": [
      {
        "condition": {

          }
        }
      }
    ]
  }
  
}

```

where i Groupby i have - carrier , rootscoreindex as col0, col1 ,  
also in values i have -3 calculated fields, (ATT, Tmobile and verizon) with aggregating to avg

where the formula for each is  
ATT `ifelse(carrier=‘AT&T’, {Rank_Carrierwise}, null)`

and where {Rank\_Carrierwise} is  
`ifelse(carrier = ‘AT&T’, {collection_rootscore_rank},`  
`ifelse(carrier=“T-Mobile”, {collection_rootscore_rank},`  
`ifelse(carrier=“Verizon”, {collection_rootscore_rank},NULL)))`

i am getting below chart where last 3 values / corners are missing Video , call & Overall, is there any solution for this

Hi @PreetiV , without having access to your data there could be a number of reasons for this such as:

1. Missing data: Verify that the fields you’re using for the visual contains data for all carriers (AT&T, T-Mobile, Verizon) across all categories
2. Calculated fields: Verify the results of your calculated field return the values as expected. Your `{Rank_Carrierwise}` formula might benefit from some simplification as this looks like it may be returning the same `{collection_rootscore_rank}` value regardless of which carrier is being evaluated
3. Consider setting the `connectNulls` parameter here to `True` or `False` depending on your needs. You can learn more about this [here](https://community.amazonquick.com/t/highchart-issue-with-null-values/42710/2).

We hope this solution works for you. Let us know if this is resolved. And if it is, please help the community by marking this answer as a “Solution" (check box under the reply).

Hi @PreetiV,

Following up here as it’s been awhile since last communication took place on this thread; did you have any additional questions regarding your initial post?

If we do not hear back within the next 3 business days, I’ll close out this topic.

Thank you
