Hi all,
I have weekly based Issues created measurment. I need to find average for previous x weeks. So for current week I need to take into account current week and 4 previous weeks; for previous week I need to take into account amount of created issues for previous week and for 4 weeks before previous and so on.
As I see there is a VisibleRowsSet() but Avg() calculates the same value for all time periods (one same digit for the whole column). And this value changes when new day, week, month started, but how can I “store” such history data?
Is it possible somehow calculate average for such time frame which shifts?
Thanks in advance!
