PowerBI - visualization settings issue

[Yaru_828]

hello Dears,

Below table is my RAW Data. The number of Enrolled Users is increasing, while the number of Unenrolled Users is decreasing month by month.

	Location	Jan-24	Feb-24	Mar-24	Apr-24	May-24	Jun-24
Enrolled Users	Country A	28	31	58	61	68	73
Enrolled Users	Country B	4	10	20	20	25	27
Unenrolled Users	Country A	49	46	19	16	9	3
Unenrolled Users	Country B	23	17	7	7	2	0
Total Users	Country A	77	77	77	77	77	76
Total Users	Country B	27	27	27	27	27	27

In PowerBI, I have added two visualization components: a slicer and a donut chart. What I want to achieve is:

When no month is selected in Slicer, that the number of Enrolled and Unenrolled users displayed in the donut chart is the same as the last month (currently June), rather than a sum of the past few months. (because the total users only 103)

now, i have no idea to adjust it, sincerely for your suggestions and assistance

you would want to use either ISFILTERED or HASONEVALUE (personally I would use ISFILTERED):

https://learn.microsoft.com/en-us/dax/isfiltered-function-dax

This is a quick throw together but your code will look something like this:

Users =
// Gets the Start of Last Month
VAR __MinDate =
    EOMONTH ( TODAY (), -2 ) + 1
// Gets the End of Last Month
VAR __MaxDate =
    EOMONTH ( TODAY (), -1 )

// if Date is selected, Sums user counts. If no date selected, Returns Last Month's users count.
RETURN
    IF (
        ISFILTERED ( [Date] ),
        SUM ( [Users Counts] ),
        CALCULATE (
            SUM ( [Users Counts] ),
            FILTER ( 'Trends', Date >= __MinDate && Date <= __MaxDate )
        )
    )

Hi @Yaru 

Based on the current data you show, you can also try this measure and use it in your donut chart visual. The logic to get the last month is through the _lastMonth variable which gets the last date in your table and convert it into yyyymm format.   

UserCount Measure = 
var _lastMonth = FORMAT(MAX('Table'[Date]),"yyyymm")
return
IF(ISFILTERED('Table'[Date]),SUM('Table'[Users Counts]),CALCULATE(SUM('Table'[Users Counts]),FORMAT('Table'[Date],"yyyymm")=_lastMonth))

Best Regards,
