Add option to show sorted CPU values

[acxz]

Describe the feature request

feature request: add an option say cpu_sort that allows showing the CPU fields sorted, i.e. CPU0 will always show the highest CPU value out of all CPUs, CPU1 the second highest, etc.

motivation: for large core systems, with the scheduler moving tasks around cpu cores, the graph seems very cluttered with crisscrossing lines. having these lines sorted by largest to smallest will let users see what the largest cpu utilization is at any given time.

current behavior:

As you can see, on a 12 core system, this graph looks like very much like gibberish. Having a notion of sorted CPU values and lines will make the data interpret able.

I came here to request this feature. Any news on it?

Not for a while, #703 was supposed to help with it but it ended up being abandoned from the looks of it.

I can take over when I have some time.
