Filter visual based on filters applied to other visuals

Hi!

I am working with student behavior dataset. I am analyzing the number of infractions committed each semester and comparing with the number committed in the previous semester. 

Screenshot 2023-05-03 092903.jpgI am further visualizing the number of infractions committed broken down by class. The following is the model view

The DAX I'm using to calculate the number of infractions committed in the current and previous semesters are as follows:

Total Infractions Current Semester = VAR CurrentDate = TODAY()
                                     VAR CurrentSemester = CALCULATE(SELECTEDVALUE(Semesters[SemesterID]), CurrentDate >= Semesters[From_Date], CurrentDate <= Semesters[To_Date])
                                     VAR Result = CALCULATE(COUNTROWS('Student Behavior') + 0, 'Student Behavior'[Behavior_Type] = "Infraction", 'DATE'[SemesterID] = CurrentSemester)
                                     RETURN Result
Total Infractions Previous Semester = VAR CurrentDate = TODAY()
	                                  VAR CurrentSemester = CALCULATE(SELECTEDVALUE(Semesters[SemesterID]), CurrentDate >= Semesters[From_Date], CurrentDate <= Semesters[To_Date])
						              VAR PreviousSemester = CurrentSemester - 1
						              VAR Result = CALCULATE(COUNTROWS('Student Behavior') + 0, 'Student Behavior'[Behavior_Type] = "Infraction", 'DATE'[SemesterID] = PreviousSemester)
						              RETURN Result

The DAX I'm using to calculating the number of students who committed infractions in the current and previous semesters are as follows:

Students with Infractions Current Semester = VAR CurrentDate = TODAY()
                                             VAR CurrentSemester = CALCULATE(SELECTEDVALUE(Semesters[SemesterID]), CurrentDate >= Semesters[From_Date], CurrentDate <= Semesters[To_Date])
                                             VAR Result = CALCULATE(DISTINCTCOUNT(Infractions_Table[SID]), ALL('DATE'), 'DATE'[SemesterID] = CurrentSemester)
                                             RETURN Result
Students with Infractions Previous Semester = VAR CurrentDate = TODAY()
                                              VAR CurrentSemester = CALCULATE(SELECTEDVALUE(Semesters[SemesterID]), CurrentDate >= Semesters[From_Date], CurrentDate <= Semesters[To_Date])
                                              VAR PreviousSemester = CurrentSemester - 1
                                              VAR Result = CALCULATE(DISTINCTCOUNT(Infractions_Table[SID]), ALL('DATE'), 'DATE'[SemesterID] = PreviousSemester)
                                              RETURN Result

The issue that I am facing is this:

When I filter one of the visuals, every visual except for 'Students with Infractions - Current Semester' and 'Students with Infractions - Previous Semester' are filtered. I understand that it probably has something to do with distinct counts.

When the visual 'Infractions by Class - Current Semester' is filtered, how can I have the 'Students with Infractions - Current Semester' visual also filtered to show the number of students who committed infractions in that particular class? Any direction will be hugely appreciated!

It looks like the class is on the student behaviour table, so you need to move the filter from there to the infractions table. Try

Students with Infractions Current Semester =
VAR CurrentDate =
    TODAY ()
VAR CurrentSemester =
    CALCULATE (
        SELECTEDVALUE ( Semesters[SemesterID] ),
        CurrentDate >= Semesters[From_Date],
        CurrentDate <= Semesters[To_Date]
    )
VAR Result =
    CALCULATE (
        DISTINCTCOUNT ( Infractions_Table[SID] ),
        ALL ( 'DATE' ),
        'DATE'[SemesterID] = CurrentSemester,
        TREATAS ( VALUES ( 'Student Behaviour'[SID] ), Infractions_Table[SID] )
    )
RETURN
    Result

Thank you so much! This worked great. I was not aware of the TREATAS function 😊
