Retrieving data for Grafana from elasticSearch

I’ve connected the PoistgreSQL base to grafana and made a query, but I can’t figure out how to map “public.ticket_time_accountings.time_unit” to
“public.ticket_time_accounting_types.name”.

SELECT 
  public.ticket_time_accountings.time_unit,
  public.ticket_time_accounting_types.name,
  public.ticket_time_accountings.time_unit AS metric
FROM
  public.ticket_time_accountings,
  public.ticket_time_accounting_types
