Help Needed to create DAX

Hi ,


I need your help to create a report. I have q requirement in which user will select an event then user will selected some static number between  to 3. For example, user has selected event number - 19 and then in second slicer user selected 2. So, i need to display total 3 lines in line graph which will show the attended participants month wise for event 19 (which selected from event slicer) and previous 2 events (number selected from second slicer). So my graph should have 3 lines (19,18,17). I have FactTable (Event Attended by Participants), EventEdition. Both tables having join (one to many) on ROW_ID from Event Table and Event Edition Wid from Fact Table and third tables contanis the static records(1,2,3) not having any join.


Can someone help to create a proper DAX? I have created below measure to get the result but it is giving only seleted event data.


# Unique Registered Contacts =
VAR MaxEvent = [Selected Event]
VAR MinEvent = MaxEvent - [Selected No of Events]
IF(VALUES('Event Edition'[Event Edition])>= MinEvent && VALUES('Event Edition'[Event Edition]) <= MaxEvent,DISTINCTCOUNT( 'Fact-Registrations'[Contact Wid] ),BLANK())

Thanks in advance.

Hi @Anonymous 


You might consider creating pbix file that will contain some sample data, upload the pbix to onedrive or dropbox and share the link to the file. Please do not forget to describe the expected results based on this sample data.
