actual it is not possible to sum the max-values per day, to get a total_max of the last year.

example: we has an counter that reset every day to 0 (=we need the value befor comes to 0 = max-value), now i will adding the max-value for every day+now to recieve the "total_max"
(monday: Maxvalue=8, tuesday: 9; wedensday:7, today max value 3 total_max=27)

i hope you understand me
