On the left I have only cpu usage sensor, which depicts some value. On the right I have the same cpu usage sensor with physical memory, swap and vram used, where it does not show up (260.56 KB, image/png)

SUMMARY
When multiple sensors are used, system monitor widget's vertical bar graph does not scale the values with automatic data range option enabled.

STEPS TO REPRODUCE
1. Add system monitor widget to tray
2. Add CPU used, Physical memory used (Bytes not percentage i.e. different units) to sensors list

OBSERVED RESULT
The CPU usage graph does not show up at all compared to the RAM value

EXPECTED RESULT
All sensor values should be scaled according to their own maximum value, 100 for percentages, maximum RAM available for physical memory used

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kernel: 6.9.5.arch1-1 
(available in About System)
KDE Plasma Version: 6.1.0

ADDITIONAL INFORMATION

I can't reproduce this issue anymore in Plasma 6.5. Looks like it got fixed along the way.
