I think I found the problem with CPU graphs... The attached data and
hourly graphs seem to highlight the fact.  When the idle% is recorded as a
number > 100 then the graph seems to just white out everything.  It
doesn't make sense that the idle% could be less than 100%.  Should I make
correction to the orcallator.se to insure it only records number up to 100
or should I just tell orcallator to treat number > 100 as 100???

With the attached graphs/data, I see the blanks for period when idle is
100.50.  I checked a handful of "good" graphs and the idle is never
greater than 100.
