MTD cumulative count on the number of dates for each month

[Anonymous]

I need a count of the number of dates in column 'CWOrdered' where date is <= to the data point (date axis) in a line graph to get a cumulative graph or MTD. I have a separate date table called 'Date' for the timeline in my graphs.

CwOrdered     MTD
2016-01-05     1
2016-01-15     2
2016-02-24     3
2016-03-20     4
2016-04-10     5
2016-05-35     6
etc. so that January 2016 = 2 February 2016 = 3 and so forth

I'm guessing it could be done with a simple count on the number of dates of the coulumn until the date where it is displayed in the line graph but I can't seem to get it working.

If I just add it to the graph I get the count of 'CWOrdered' as a straight line in the graph which isn't very helpful 😃

Should be something along the lines of:

Measure = 
VAR __maxDate = MAX('Calendar'[Date])
VAR __table = FILTER(ALL('Table'),[CwOrdered]<=__maxDate)
RETURN
COUNTX(__table,[CwOrdered])
