This report shows the number of transaction per hour
over a range of dates.
The rows are always hours. The columns are either calendar
dates or named weekdays (e.g., Monday, Tuesday) if grouping
by week day.
If a Buyer/Dept option is used, the result will
be transactions from that super department. Otherwise, the result
will be transactions from the specified department range. Note there
are a couple special options in the Buyer/Dept list:
All is simply all transactions and All Retail is
everything except for super department #0 (zero).
