Calculating Percentage of Y/N on a Month-over-Month Basis

[Anonymous]

I have two columns, as shown below:

I've currently calculated the "% Y" rate in the "RECOMMENDED" column using the following formula:

% Yes = 
DIVIDE (
    CALCULATE ( COUNT ( SA_Rec_Rate_Fact[RECOMMENDED] ), SA_Rec_Rate_Fact[RECOMMENDED] = "Y" ),
    CALCULATE ( COUNT ( SA_Rec_Rate_Fact[RECOMMENDED] ), ALLSELECTED ( SA_Rec_Rate_Fact[RECOMMENDED] ) )
) 

My question is this:  How do I calculate the "% Y" rate for each indivdual month? I would like to visualize this as a line chart with the months on the X-axis (September 2019, October 2019, etc.) and the "% Y" rate on the Y-axis.

Hi @Anonymous,

First, you can add one calculated column with formula：

format('SA_Rec_Rate_Fact'[DATE_QUALIFIED],"MMMM YYYY")

in table, then applied this new added column in visual Axis and the measure 

in visual Values just like in below screenshot:

Create a date table, Join you date with that and have month year there.

Create a month subtotal

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

Create a month column using MONTH([DATE_QUALIFIED]). Use that in your Axis and your measure in your Values.
