Maybe this will work for you or give you an idea for your need.

var query = {}
var filter_by = 'Day'
var graph_data = [1, 2, 3, 4, 5, 7, 3, 12, 4, 2, 5, 6]
if (location_id == '') {
  switch(filter_by) {
    case 'Day': 
      query.created_at= {
        gt: current_date
      }
      query.ref= headerData?.ref
    break;
    case 'Week':
     query.created_at= {
        gte: startofweek_date,
        lte: endofweek_date
      }
      query.ref= headerData?.ref
     break;
     case 'Month' :
       query.created_at= {
         gte: startOfMonth_date,
         lte: endOfMonth_date
       }
       query.ref= headerData?.ref
      break;
      case 'Year': 
        query.created_at= {
          gte: startOfYear_date,
          lte: endOftheYear_date
        }
        query.ref= headerData?.ref
      break;
      default: 
        query.created_at= {
          gte: custom_start_date,
