Grafana: How to change envs?

Hello everyone,
I am trying to change the date formats of Grafana and as far as I can see, this can only be done by changing the envs.

However, it seems either my syntax is wrong for HA implementation or it is not being applied

env_vars:
  - name: GF_DATE_FORMATS
    value: interval_hour = DD.MM HH:mm
  - name: GF_DATE_FORMATS
    value: interval_day = DD.MM
  - name: GF_DATE_FORMATS
    value: interval_month = MM.YYYY

All my graphs are still showing default date formats

Does anybody know the correct syntax?

Thank you :slight_smile:

Thanks to @RobC on the discord server, the correct syntax should have been:

env_vars:
  - name: GF_DATE_FORMATS_INTERVAL_HOUR
    value: DD.MM HH:mm
  - name: GF_DATE_FORMATS_INTERVAL_DAY
    value: DD.MM
  - name: GF_DATE_FORMATS_INTERVAL_MONTH
    value: MM.YYYY
