SUMMARY
The automatic range shown seems out of range & might show 100 * core % for some reason.

STEPS TO REPRODUCE
1. Open the system monitor
2. Enable Data Ranges > Automatic Y data range (enabled by default)
3. See weird %


OBSERVED RESULT
Y scale shows 1600% for me.

EXPECTED RESULT
Y scale should be at 100 %. Disabling the automatic Y data range option will switch to 100%.

ADDITIONAL INFORMATION

Comment 1 Nate Graham 2025-01-13 21:18:58 UTC

That's because the cores' numbers are being combined here, not scaled. There's a separate scaled data source that will have 100% be the top number on the Y axis.
