Graph with span: end: day 1rst value issue

[manu3b1]

Hi,
I get strange value for the 1rst item of a hourly chart: it is always far too high compared to what is reported on larger chart, as if it contains the whole day:
Here the charts for 1 day, 2 days and 3 days about the same data:

type: 'custom:apexcharts-card'
graph_span: 2d
header:
  title: Conso par Heure
  show: true
  show_states: true
  colorize_states: true
apex_config:
  legend:
    show: false
span:
  end: day
now:
  show: true
all_series_config:
  stroke_width: 2
  show:
    legend_value: false
series:
  - entity: sensor.linky_hc
    name: Linky HC
    type: column
    transform: return x / 1000;
    unit: kWh
    group_by:
      func: diff
      duration: 60min

Looks like it is linked to the “end: day” option mixed with "fun: diff":

span:
  end: day

Thx.

Could you try with fill: 'null' in the group_by please? Also another idea would be graph_span: 2h-1s.

PS: for now I can't reproduce so it seems linked to what your sensor history looks like in home assistant (if you also mind sharing a screenshot, it could be helpful)

Same issue with each of these tricks.
Here are the data viewed by HA:

I've reproduced the issue with a simple incremental sensor:

sensor:
  - platform: template
    sensors:
      counter:
        friendly_name: "Counter"
        unit_of_measurement: "s"
        value_template: "{{ as_timestamp(now()) }}"

automation:
  - alias: "Update counter"
    trigger:
      - platform: time_pattern
        seconds: "/1"
    action:
      - service: homeassistant.update_entity
        target:
          entity_id: sensor.counter

Great, I'll try to use that to debug, thanks 👍
