State last fails to render card

[MrWaggel]

Changing the state to last fails to render the card;

type: custom:mini-graph-card
group_by: date
hours_to_show: 168
aggregate_func: diff
icon: mdi:lightning-bolt
height: 80
entities:
  - entity: sensor.p1_meter_energy_import
name: Electricity Consumption
show:
  graph: bar
  state: last

Any other value renders it correctly, but I wish to see the value of the last bar.

Entity data comes from the Homewizard Energy P1 meter

For me it actually renders sometimes if I have multiple graph on the same view. But not with the last diff, but the last actual state (I guess expected.)

Would be great if this could show the diff for each day, and also the diff for the current day as the state. E.g.:

      - type: custom:mini-graph-card
        entities:
          - entity: sensor.consumption
            show_state: true
            aggregate_func: diff
        hours_to_show: 72
        group_by: date
        show:
          graph: bar
          state: diff

Would be great if it could show the last period as the state.

This doesn't render:

        - type: custom:mini-graph-card
          entities:
            - entity: sensor.kamstrup_energy
              aggregate_func: delta
          hours_to_show: 72
          group_by: date
          show:
            graph: bar
            state: last
