I'd use a reduction group and trend the reduction group.

Subject: [foxboro] 24 hr rolling average
I know we have already ventured down this path once but at the time
rolling
average didn't interest me and I didn't give it a passing
thought...now it
does.
My question is: How would you program for a 24 hour rolling average
(my case
is a flow) say sampled every 5 minutes (288 samples per day)? I
also need
to trend the result.
