Count number of tests

[brettg]

Hello,

I would like to make a table which shows me users with 1 test, 2 tests, 3 tests etc. Something like the below based on the data set.

I know I could do this using "group by", but then I wouldn't be able to look at historic data. Is there a way to do this with a measure that would consider the date slicers on the page? (If I change date slicers, only tests in that period are counted)

Test Count	Number of users
1	1
2	2
3	1

UserID	Gender	Age	TestResult	TestDateTime
006	Male	34	PASS	2022-02-01 19:50:10.897
001	Female	29	PASS	2022-01-31 18:35:25.830
004	Male	25	FAIL	2022-01-30 10:50:48.873
001	Female	29	PASS	2022-01-28 11:39:51.737
001	Female	29	FAIL	2022-01-27 11:49:38.180
002	Female	36	PASS	2022-01-26 15:07:48.967
004	Male	25	PASS	2022-01-25 14:56:13.130
006	Male	34	PASS	2022-01-24 17:41:15.973

Hi @brettg ,

Firstly, create a table for "Count":

New Table = {1,2,3}

Please try:

Count = 
CALCULATE(COUNTROWS('Table'),FILTER(ALLSELECTED('Table'),[UserID]=MAX('Table'[UserID]) &&  [TestDateTime]>=MIN('Table'[TestDateTime]) && [TestDateTime]<=MAX('Table'[TestDateTime])))

Count(again based on meassure) = 
var _t=SUMMARIZE('Table','Table'[UserID],"Count by UserID",[Count])
return COUNTROWS(FILTER(_t,[Count by UserID]=MAX('New Table'[Test])))+0

Output:

Hi Eyelyn,

This is perfect thank you! Just what I was looking for.

Where you've done {1,2,3} on the new table, would it be simple for me to go up to 10 and then include "10 or more"? 

Kind regards,

Brett

Not quite what I'm looking for I'm afraid! SelectedValue won't work when my date slicer is between two values.

I think I need two measures? one to count the distinct UserID's and another to group them

Hello,

I need the measure to do a distinct count for "UserID" from the second table. 

Then I'd like to create the first table by grouping the user counts into repeat test usage.

Measure = CALCULATE(distinctCount(Table[UserId]),selectedvalue( Table[date]))

[mh2587]

Measure = CALCULATE(Count(Table[Test]),selectedvalue( Table[date]))
