Grouped line chart that shows count per month

petervandenberg — Fri, 26 Apr 2024 14:59:02 GMT

Hi, I have a problem getting the output that I need.

I have a dataset ('data') with two columns ('name' and 'date'). What I want is very simple (at least I thought so):

I want the following grouped line chart:

- It is grouped by name

- The x-axis is date

- The y-axis should give the percentage of rows of a specific name in a specific date relative to all rows that date.

So if there are 10 rows on the first of march, and there are two rows with the name 'Peter' on the 1st of march, I want the percentage of 'Peter' on the first of march to be 20%.

As simple as that. From what i've read, it must be done using DAX, however, I cannot find the right query. Right now I have
DIVIDE(
COUNTROWS(FILTER('data', 'data'[Name] = EARLIER('data'[Name]))),
CALCULATE(COUNTROWS('data'), ALLEXCEPT('data', 'data'[Date]))
) * 100

But this does not seem to give the right answer.

Can anybody please help me out?

Hi petervandenberg ,

According to your description, here are my steps you can follow as a solution.

(1) This is my test data.

(2) We can create a measure.

percentage = var _a=COUNTROWS(FILTER(ALLSELECTED('Table'),[date]=MAX('Table'[date]))) var _b=COUNTROWS(FILTER(ALLSELECTED('Table'),[date]=MAX('Table'[date]) && [name]= MAX('Table'[name]))) RETURN DIVIDE(_b,_a,0)

(3) Then the result is as follows.

If I have misunderstood your needs, please clarify in a follow-up reply.

Best Regards,

Neeko Tang
