How to get last row value when using cyclic groups
I would like to create a bar chart that has as time dimension a cyclic group Day/Week/Month and as expression something that shows the number of total members at the end of the time period, not the average or sum , but the last row.
For example if Day is selected
Day
Number of Members
10.04.14
44776
11.04.14
44815
14.04.14

if Month is selected then I have
Month
Number of Members
avr. 2014

that is for each month I have the number of members of the last day of that month.
Since I work with business days, last day of week or month for me is the last data point I have for that week or month not the calendar day.
