Description

The "Idle" data value shouldn't be graphed in the Dashboard "CPU Usage" widget. The entire point of a dashboard is to provide a quick overview of the system at a glance, and including the Idle "usage" in the graph at best (idle system) means that the small usage is hidden in the noise at the bottom of the graph, and at worst (semi-busy CPU) makes the graph a meaningless jumble of noise.

For example this is what it looks like on my system with a background job that was spiking the CPU:

As a point of comparison, the RRD graphs used in the legacy interface do not graph the Idle time:

I would also argue that it shouldn't be graphed on the reporting, but I can see it being shown in the more detailed view there.
