As the time axis is present already, as mentioned in comment 2, and the
remaining issue is that the cpu usage from the resource tab is not
scaled based on the cpu frequency scaling, I am marking this bug as a
duplicate of bug #214695, the bug about the frequency scaling-related
issue.

Title:
  the "CPU History" graph info is unclear

Bug description:
  Binary package hint: gnome-system-monitor

  Hi! This report is about System Monitor 2.18.1.1, running on Ubuntu
  Feisty. It would be a nice fix for Gutsy.

  Currently the CPU History graph in the System Monitor is a nice tool
  for a quick estimate of the current CPU usage, but only for a very
  rough estimate. The main problem is that the units are not very clear:
  the time axis is not marked at all, so I can at most estimate how long
  a spike took; the height is marked in percent -- but doesn't mention
  exactly of what.

  I'm using Ubuntu on a Centrino Duo laptop, which can change the
  frequency of each processor according to several factors. (I'm not
  sure if it can scale each core separately, though. The factors I know
  are load and whether or not I'm plugged in, there may be some other
  heuristics.)

  All this means that xy % processor usage can mean very different
  things in terms of how much work the computer is doing. At the very
  least, the legend below the graph -- [color] CPU#: ##.# % -- should be
  changed to something like [color] CPU#: ##.# % usage (at ## GHz) --
  though this doesn't fix the graph. Maybe a different line (different
  shade or dotted) could indicate the frequency of the processor.
