History Graph not updating template entity

Configuration Frontend
1

I have templates to show water usage in minute from water counter.
Automation updates templates once per minute and all works expect History Graph card updates only when I click browser update.
Graphs move left but lines remain straigth until I refresh browser page.

Any idea how to force History Graph update?

Hi, I have the same kind of problem: history graph is not updating at all (version 2022.6.6).
Did you solve your problem anyhow?

Actually back then this problem disappeared after some time, probably some update solved it.
Few weeks ago I noticed same effect on my very old tablet. There I must refresh browser for graph update.
On PC graphs update only when values changes, so I’m not happy. Graphs must move with time.

I’ve noticed that one of my History Graphs is now getting stuck, but others seem okay.
