Get last 6 months in DAX with limited data

My current example dataset I'm working is below:

Event NameDateType
Event 113-Apr-20In Person
Event 25-May-20Online
Event 321-Jun-20Online
Event 45-Feb-20In Person
Event 524-Feb-20Online

 

I'm trying to use DAX to create a table that shows # of events across last 6 months similar to below. However without data on July/August, I'm not sure how to create columns to those 2 months. Is there any way I can create the table using these constraints?

Hi @Pillz ,

 

If you want to display the last 6 months in the table. You can try to create a calendar table. There are two ways to achieve its functionality: implemented with a filter or implemented in a table.

 

1. implemented in a filter:

a. You can create a calendar table like below and then sort [MonthName-Year] column by [Month-Year] column.

 

Calendar = 
ADDCOLUMNS (
    CALENDAR ( DATE ( 2019, 1, 1 ), DATE ( 2020, 12, 31 ) ),
    "Month", MONTH ( [Date] ),
    "Year", YEAR ( [Date] )
)
MonthName = FORMAT ( 'Calendar'[Date], "mmm" )
MonthName-Year = 'Calendar'[MonthName] & "-" & 'Calendar'[Year]
Month-Year = 'Calendar'[Month] & "-" & 'Calendar'[Year]

b. Create relationships between the two tables.

c. Create a measure.

 

count = COUNTROWS('Table')+0

 

 

d. Create a Matrix visual and set a filter on the visual.

2. implemented in a table:

You can just create a dynamic calendar table containing only the dates of the previous 6 months based on today's date.

 

Last 6 months = 
ADDCOLUMNS (
    CALENDAR ( EOMONTH ( TODAY (), -7 ) + 1, EOMONTH ( TODAY (), 0 ) ),
    "Month", MONTH ( [Date] ),
    "Year", YEAR ( [Date] )
)
MonthName = FORMAT('Last 6 months'[Date],"mmm")
MonthName-Year = 'Last 6 months'[MonthName]&"-"&'Last 6 months'[Year]
Month-Year = 'Last 6 months'[Month]&"-"&'Last 6 months'[Year]

 

 

And then, follow the steps of the previous method. However, there is no need to filter on date.

@Pillz you should create a measure like this

 

Count = COUNTROWS ( Table ) + 0

 

and then use this measure in the matrix.
