Parse Duplicate days in a count in a Table

[ScottJones1]

I have grouped table, The Incidents might get multiple survey entries a day from different people. I just want to show how many days we have been on an incident. Is there a way to parse out duplicate days?

return {

  cells: {

    Incident_: {

      displayText : $datapoint.Incident_,

      textColor: '',

      backgroundColor: '',

      textAlign: 'left',

      iconName: '',

      iconAlign: '',

      iconColor: '',

      iconOutlineColor: ''

    },

    COUNT_DATE_OF_EVENT: {

      displayText : Text($datapoint.COUNT_DATE_OF_EVENT),

      textColor: '',

      backgroundColor: '',

      textAlign: 'right',

      iconName: '',

      iconAlign: '',

      iconColor: '',

      iconOutlineColor: ''

    }

  }

}
