Adding Columns for results of survey that get zero responses.

[travbum]

This is some data of before and after students take a class:

Question1 Before	Question 1 After
A	A
B	C
C	C
C	C
D	C
C	C
C	C
C	C
A	A
B	C

Before, students selcted A, B, and C as answers. After most of them realized C was the correct answer. Some still selected A, but none selected B. However, in my final graph, I only can chart A and C. How would I include that B is 0?

hi, creating a measure like this:

COuntQ =
    VAR COUNTING =
        CALCULATE (
            COUNTROWS ( Table2 ),
            FILTER (
                ALL ( Table2 ),
                Table2[Question 1 After] = VALUES ( Table2[Question1 Before] )
            )
        )
    RETURN
        IF ( COUNTING > 0, COUNTING; 0 )

and i the visual chart select the fields in this way;

If you're willing to change your table layout slightly,  this is fairly simple. Use three columns: Question #, Before, After.

Then, you can create a calculated column for each answer type A, B, and C in your Before and After groups:

beforeA = IF([Before]="A",1,0)

beforeB = IF([Before]="B",1,0)

beforeC = IF([Before]="C",1,0)

afterA= IF([Before]="A",1,0)

afterB = IF([Before]="B",1,0)

afterC = IF([Before]="C",1,0)

Finally, then you graph the before and after results.
