I'm trying to get a total count of all the rows and show the increase or decline each month. Tried some of the examples here with running totals etc but can't make it work.
I don't have a sum, but it's the amount of total rows that have a date greater than the last month I want to show.
So I have 100k rows. With a date, a guid, productgroup, name etc.
So I want to show the following in a graph
2016-01 -- 100k rows
2016-02 -- 99k rows
2016-03 -- 98k rows
2016-04 -- 99k rows
etc etc.
Anyone got any suggestions? And have I explained properly or do you need more info?
