Allow for 4 digits (%7.2lf) in front of the decimal for "# of jiffies"
on the aggregation chart (works for up to 9999 jiffies before the table
at the bottom of the chart goes out of alignment).  For cases where you
have more then 99 CPUs to be aggregated, you will need to increase the
number of digits (%8.2lf for 999 CPUs) or (%9.2lf for 9999 CPUs).
