hi, i’m new to Influx, i can not figure out a way to calculate something like last period change percentage and same period last year change percentage.
Suppose i’ve got the following data:
insert sale value=110 2018-10-01T00:00:00z
insert sale value=112 2018-11-01T00:00:00z
insert sale value=110 2019-12-01T00:00:00z
the last period is calculated by: (value_this_period - value_last_period) / value_last_period.
How to do with Influx or QL?
Thanks
