That argument can be applied to any report with a floor - I don't think
time reports would be especially misleading.

Nope, I just want to see the traffic spikes. Specifically, I want to see
if some recent events that required a server to be rebooted might be
related to a traffic spike on one particular VHost. I want to use the
FULLHOURLY report almost as designed, but I want to quickly pick out the
spikes, rather than scrolling through a 2,000 line report. (Or longer,
if I decided I need to go to the 5 minute or quarter hour report).
I took the slightly more laborious step of checking the window around
each of the reboots, to see if there was a spike immediately preceding
it, and there doesn't appear to be. As I under stand it, the main
purpose of the time reports is to give you a visual clue about your
traffic patterns. This is what I was trying to get, without the
"clutter" of lots of empty space (yeah, I know that sounds
contradictory).
And this may be unusual - I'm looking at a site that gets one or two
hits per hour most of the time, with 3 or 4 hourly periods per week
where it gets a couple of hundred hits. I'm interested in maybe 40
hourly periods in the last 2,100, and they don't occur regularly. I
thought I'd be able to get some quick and dirty data from Analog that I
could use to make a decision about how to proceed in this case.
