Week Number Time Resovlved Cumulative Database Entrie Dashboard Display

[lswanson1]

So I am a new Power BI user and I am setting up a dashboard for a Sharepoint List database.  All entries are data/time stampled.  I wish to display the cumulative entry totals per annual week number (1-52).  For example, the first week of January might have 4 entries throughout the week, so on x axis would be 1 and y axis total is 4.  For second week of January, there are 4 new entries, so the x axis would be 2 and the y axis would be 8, not 4.  Hope that is clear.  My problem is visualizing the cumulative entry numbers as well as correlating a data/time stampl with a week number.  Any help is greatly appreciated.

@lswanson1 , You use a formula like this with date calendar. In the calendar you can have a week, month , qtr etc.

What you choose (Week), this will be cumulative of that. Use week on the axis/rows

Cumm Sales = CALCULATE(SUM(Sales[Sales Amount]),filter(date,date[date] <=maxx(date,date[date])))
Cumm Sales = CALCULATE(SUM(Sales[Sales Amount]),filter(date,date[date] <=max(Sales[Sales Date])))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

So I was able to get the plot for weeks per year number on the x axis to work with a calendar table.  I am still working on the cumulative sum portion.  My attempt is this:

Measure = TOTALYTD(COUNTROWS('Table Name'), 'Calendar', Calendar')

So as you can see, I have no clue how to set the start and end dates.  What I want is to have the start date be the start of the current calendar year and the end date be either today or the end of this year if future dates can be set.
