Description Dennis Schridde 2020-08-20 10:55:26 UTC 
OBSERVED RESULT

I would like to plot CPU temperature in °C and CPU clock frequency in MHz in the same graph.  Since both use the same scale, the clock frequency (>1000) dominates the temperature (<100) and the resulting graph does no longer have high enough resolution to be useful.

EXPECTED RESULT

Using separate scales and min/max values for sources of different units (°C and MHz) would alleviate my problem.

Could you show a possible graphical representation of two (or more) differently scaled axes?

Two differently scaled axes would have one on the left and the other on the right.  More than two axes, which each having a different unit or being differently scaled would be non-trivial to display on a two dimensional chart.  Thus I would consider them out of scope for this request.

The two-scales plot for easily seeing correlations of functions of different units could look like this: https://en.wikipedia.org/wiki/Multiple_comparisons_problem#/media/File:Spurious_correlations_-_spelling_bee_spiders.svg

I'm afraid these widgets have been deprecated in Plasma 5 and removed in Plasma 6. They have been replaced with the newer System Monitor widgets.
