How to get Temperature History Graph with weekdays?

I need help figuring out how to get a temperature history graph with weekdays and time-stamps that always starts with 00:00 and then 6 hours in between.

In my configuration.yaml

  - platform: template
        value_template: "{{ ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'][now().weekday()] }}"

In my ui-lovelace.yaml

  - title: "Väder"
    panel: true
      - type: history-graph
        title: "Temperaturer"
        hours_to_show: 120
        refresh_interval: 60
          - entity: sensor.badrums_sensor_temperature
            name: "Badrum"
          - entity: sensor.entre_sensor_temperature
            name: "Entré"
          - entity: sensor.fibaro_system_fgms001_zw5_motion_sensor_temperature
            name: "Hall ÖP"
          - entity: sensor.dayoftheweek

I just added the “entity: sensor.dayoftheweek” to show that it worked so far.

This is what I get:

I hope someone can guide me in the right direction
