26        were registered.  The array values are the labels that
27        will be used in the input and output power plots.
28
29        For Example:
30        ::

36        a label for the load and allfreqs plots.  It's recommended that
37        the names of the cpus matches those in actor_order.

39        For Example:
40        ::
