I have a table showing people's names, a start date and an end date. I am wanting to make a plot where it shows when (in the past 6 months) people have been active.
My table looks something like
NAME | Start | End
---------------------------
Bob . | 2019-02-01 . | 2019-08-23
Joe . | .2011-05-15 . | 2019-08-28
John | 2017-02-5 . | 2018-05-08
And what I am hoping to make is a table (for plotting) like this
DATE . | . # of active users
---------------------------------
2011-04 . | . 0
2011-05 . | 1 . (where joe starts)
2011-06 . | . 1
...
2017-01 . | . 1
2017-02 . | 2 . (where john starts)
2017-03 . | . 2
...
2018-04 . | . 2
2018-05 | . 2 . (where John stops)
2018-06 . | . 1
...
2019-01 . | . 1
2019-02 | . 2 . (Bob starts)
2019-03 . | . 2
...
2019-07 . | . 2
2019-08 . | . 2 . (both Bob and Joe stop)
2019-09 | 0
I can't seem to get Power BI to behave when it comes to date extrapolations. Any help is greatly appreciated!

Hi @Anonymous ,
At first, you need a calendar table.
Date = CALENDAR ( MIN ( 'Status'[Start] ), MAX ( 'Status'[End] ) )
Then add a column to get YEAR&MONTH.
YM = YEAR ( 'Date'[Date] ) * 100 + MONTH ( 'Date'[Date] )
Then add column “startYM” and column “endYM” in another table which contains names.
StartYM = YEAR ( 'Status'[Start] ) * 100 + MONTH ( 'Status'[Start] )
EndYM = YEAR ( 'Status'[End] ) * 100 + MONTH ( 'Status'[End] )
Cross join two tables.
Table = CROSSJOIN ( DISTINCT ( SELECTCOLUMNS ( 'Date', "YM", 'Date'[YM] ) ), 'Status' )
Add a new column to get the count and use a new measure to sum it.
count = IF ( 'Table'[YM] >= 'Table'[StartYM] && 'Table'[YM] <= 'Table'[EndYM], 1, 0 )
Measure = SUM ( 'Table'[count] )
Now , you can use visuals to get result.
