Illustration with a custom:mini-graph-card - Lower part gone?

[barthel-eu]

After installation, I only changed the name in the entity to mine and it shows nicely the upper part, but the curve on the lower part is completely missing?

Side issue, the times should be 24-hour clock as everywhere else in my HA installation? Checked in the user settings, set to 24h 😳

Hello,
I think this is more an issue with the card usage than with the Librelink integration

Different from the App, it seems that the curve only starts to "fill" after the card has been created, the previous data ain't shown initially. By coincidence I just checked on my "test-board" and found it showing data now.
It's still somewhat disturbing that the time is shown using 12-hour-clock. Will see now, if I can trigger some added automation.
