Dear all,
There are two columns with data: `time` (time scale in steps of 10 minutes) and `val` (amount of transactions).
I need to calculate median values (med_val) for the `val` column for 7 weeks. The specific example for the point 12.04.2018 15:00:00 med_val = `median` ( `val` by 7 points. 5.04.2018 15:00:00, 29/03/2018 15:00:00, 22/03/2018 15:00:00, 15/03/2018 15:00:00, 8/8/2018 15:00:00, 03/03/2018 15:00:00, 22/02/2018 15:00:00), i.e. so median at 7 same time points on the same days of the week. If there are no data, then we consider that 0 transactions were performed.
The best that I could come up with is:
| timechart span=10m median(val) | timewrap 1w series=exact
Are there any good solutions?
Thanks in advance!
