History graph needs minutes instead of tenths of hours

Is there a way to do this in yaml?

Like the feature to add a name.

  - type: history-graph
    entities:
      - entity: sensor.water_temperature
        name: mywater
        display: minutes   

Do people prefer 0.10h ?
Can I default the card to minutes somewere else?

The units it shows are based on how much room is on your graph. If the graph can’t show 15 minute increments, that means there isn’t enough space to do so.

No

Test this:


  - type: history-graph
    entities:
      - entity: sensor.water_temperature
        name: mywater
    hours_to_show: 0.25

10 minutes would be .166666. But I’m pretty sure OP is asking for the scale to be larger but with 10 minute increments displayed.

My post was mainly about a granularity of a scale: the smaller period you define the smaller granularity you will see (which is obvious).
