Thanks Stephan... I'm new to perl too so excuse the ugliness. The basic
graphing part of the script is what follows. I also include 3 sample gifs
for week/month/year.
Any futher assistance is greatly appreciated.

/j-p.

Maybe I'm getting you wrong, but most times the MAX over the year is
higher
than the MAX over the month. If you store a datasource with consolidation
MAX, you won't lose any peak, and because of the longer period...
Another point is, that in the 5-minute graph, you have 6 maximum values
that
go into one for the 30-minute graph. This means, that through
consolidation,
you lose the low values in your MAX graph.
Well, if you compare the same period, the really MAXes should be the same,
what if you send the code you use, so we could have a look at it...
Best regards,
Stephan
