1. your heartbeat is set to 300, as is your step size. You probably
don't want that.
2. Why do you use absolute? You probably want to use gauge.
3. 24 samples of 300 seconds does not make 24 hours.
4. --lower-limit, --upper-limit and --rigid will help you to fix your
5. your numbers will get interpolated unless $date div 300 == 0. May not
be a problem, as long as you know.
