only if you can mathematically define what a peak is.
Let's say you could CDEF/VDEF the AVERAGE and the MAX over the entire
period and then define that everything between AVG & MAX is a peak.
That could be trended ... but that's probably not what you want.
You could also define a new rra::MAX with a period of maybe 1 hour
and then trend the values out of this rra ...
I have similar problems where a certain behavior is easy to spot
visually but almost impossible to define mathematically ...
