How to create % restricted to a certain group?

[laurelning]

Hello all,

        I am trying to tap into the community of experts in Power BI to see if I can get some help create  a bar chart comparing the percentages of drop-out between the intervention and control groups across 5 semesters. It doesn't seem very straightforward to me though it can be quicly done in Excel. Could I use your expertise for some guidance as to how to create the chart? Below the first table shows dropout rate for each semester by intervention. The second table shows the corresponding percentages only. The chart shown below is what I intend to create in Power BI but can't get it work. The following two links give access the test data and pbix file:

Thank you very much!

Hi, @laurelning 

It’s my pleasure to answer for you.

According to your description,I think you can create some measures to display the cluster bar chart.

Like this:

Measure0 =
VAR a =
    COUNTROWS ( ALL ( 'Raw Data' ) )
VAR b =
    COUNTROWS (
        FILTER (
            ALL ( 'Raw Data' ),
            [Semester] = SELECTEDVALUE ( 'Raw Data'[Semester] )
        )
    )
VAR c =
    DIVIDE ( b, a )
VAR d =
    COUNTROWS (
        FILTER (
            ALL ( 'Raw Data' ),
            [Semester] = SELECTEDVALUE ( 'Raw Data'[Semester] )
                && [Dropout] = 0
                && [Intervention] = 0
        )
    )
RETURN
    DIVIDE ( d, c ) / 100

Here is my sample .pbix file.Hope it helps.

If it doesn’t solve your problem, please feel free to ask me.
