0.12.0-dev.2

Observe this error in Browser console for ALL entities which were not changed within a selected period:

  1. DB size did not change within 4 days (> 24 hrs which is a default value for hours_to_show)
type: custom:mini-graph-card
entities:
  - sensor.home_assistant_v2_db_size

  1. This input_number helper was not changed for a long time.
    Consider this card:
type: vertical-stack
cards:
  - type: custom:mini-graph-card
    entities:
      - input_number.testing_device_class_apparent_power
  - type: history-graph
    entities:
      - entity: input_number.testing_device_class_apparent_power
  - type: entities
    entities:
      - entity: input_number.testing_device_class_apparent_power

Now the graph is not displayed, same errors in the console:

Change the helper's value - then the graph will be displayed w/o errors:

  1. Any sensor which value was changed more than 15 minutes ago:

That might be related to the way, HA reports history. I believe, if we ask it "what is the history of the last hour?", it will respond with "nothing" if there were no changes. If we want to fix that, we have to also ask it "What's the current state", and just use that in a flat line.

Not sure, if that's already what we're doing. If it's not, it will be quite some code change. Then, just displaying a message instead of the graph might be easier: "no changes in the last X hours".

Tested with 0.11:
no errors, graph IS displayed, also plenty of "fetch" messages in console:

it will be quite some code change.

I just upgraded to 0.12.dev version - and got these "no graph displayed" issues for MANY of my graphs.
Earlier these graphs were displayed as flat - and it was OK since it was true.
As you can see in the post above, downgrading to 0.11 again caused these graphs displayed.

Then, just displaying a message instead of the graph might be easier: "no changes in the last X hours".

This will be absolutely not informative, 99% of users will expect flat lines in this case.

Hmm... OK. So it's good I didn't fire the release script on the master branch. 😆

It might be my change here: 527f005

That's the only difference in calcPoints I could find.

fix: retain the last out-of-bounds state
8486943 
This re-insures the logic to keep the last known state before the start of our grah interval within the history.
While this is not really correct, it allows for rendering state-state-graphs.

This element was mistakenly removed in kalkih#881.

The piece of code relies on history being chronographical.

Seems to be solved by #961 (changes not yet added to a release)
@akloeckner - thanks a lot!
