[REQUEST] CPU graph with classic bar-chart (instead of symmetric bar-chart)

**Is your feature request related to a problem? Please describe.**

I personally am not able to see at a glance how much CPU usage is going on with this symmetric chart.

**Describe the solution you'd like**

I think I'd prefer a classic bar-chart where all bars start at the same horizontal line, reaching a max at a common top line which is clearly identifiable. At least this is the kind of visualization which would not lead to open questions.

**Describe alternatives you've considered**

Alternatively, a better visual clue or online help how to interpret the symmetric graph that is currently shown would be nice. At my side, there are four vertical stacked dots per [I don't know] followed by a vertical space. Are those four stacked dots per one percent average CPU usage?
