If it ain't broke, I'll fix it!

Nasty, but not as nasty as it looks. Please never truncate the y-axis...
This is why I also included the relative percentage change ranges. Alternatively could share an image twice as tall to zero the y-axis. Chart doesn’t change
That was a misstatement on my part, it would be a more accurate picture - you’re right. I didn’t intend to mislead however.
Yea, all good. Just a pet peeve of mine. Especially since Grafana "helpfully" does this per default, it seems.
This is why I force all my CPU graphs to 0-100% scale. Resolution doesn't matter at that point; there's no point in zooming in across a smaller Y range since ~1% CPU usage variations are just noise anyway.
