Lovelace - History graph card

Hello!,

I’d like to ask about strange behavior in history graph card.
At 11:00 I have changed value of “Floor Heating SP” variable from “21.2” to “19.0”
The change was sudden, and history chart of this variable should be more like one horizontal line, and one (almost) vertical with slope from 21.2 to 19.0 within 1sec.
Instead it looks like it was changing slowly in the time.
State before change - 21.2:
before_11h13
State after change - 19.0
after_11h13
Could you give me some hints what may be wrong ?
Thank you

Home assistant just joins the dots between the last state and the new one. As the last state change was probably off the graph it is drawing from the oldest point on the graph to the new state point.
