How to get Temperature History Graph with weekdays?

Configuration
1

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

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

In my ui-lovelace.yaml

  - title: "Väder"
    panel: true
    cards:
      - type: history-graph
        title: "Temperaturer"
        hours_to_show: 120
        refresh_interval: 60
        entities:
          - 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:

Temp%20graph%20help
Temp%20graph%20help953×308 19.8 KB

This is what I want:

Temp%20graph%20help%202
Temp%20graph%20help%2021067×237 20.4 KB

I hope someone can guide me in the right direction
