So did i... ;-)

on behalf of the average load. On the other side, it may be interesting if
you are developing and want to countercheck the performance of a script
or a new binary. On active (and busy) servers the # of cpus will be a point
of interest because of the possibilty to check out if the system has enough 
cpus...

The difference in the colours is that in procallator the line colour for the
# of cpus is red and in orcallator it is magenta. From a logical point of
view,
the red line could be seen as an alarm signal if it crossed by the load.
I agree that the colours should be consistent within the same graphs.
