VRM Dashboard min/max values incorrect

Here’s the English translation:

I’m noticing something strange in the VRM Dashboard.
When I look at the battery min/max values, I see that percentages are lost between the hours. For example:
From 12:00 to 13:00, the min/max is 74-83%:

From 13:00 to 14:00, the min/max is 62-71%:

I think this might be a small graphical bug, but it’s still noticeable that these numbers don’t line up.
