statistics: clarify CPU/processor graph by removing "idle" from it

Clarify the CPU time consumption graph by removing the "idle" data from it.
Especially with light traffic, removing "idle" enables the graph
to scale better and to properly show the CPU load variations.

If "idle" data needs to be seen, it might be added as a second graph below.
