Percentage of False in a column from a Month row

[ymirza]

I have table with name, month and rate. What would be the appropriate DAX to measure percentage of False only from that specifc month (not the total column of Rate)?

for e.g. Jan has 6 names and 3 false. should return 50% under Jan.

Month	Name	Rate
Jan	Adam	TRUE
Jan	Mark	FALSE
Jan	Jane	TRUE
Jan	Jacob	FALSE
Jan	Steven	TRUE
Jan	Jones	FALSE
Feb	Adam	TRUE
Feb	Mark	FALSE
Feb	Jane	TRUE
Feb	Jacob	FALSE
Feb	Steven	TRUE
Feb	Jones	FALSE
Mar	Adam	TRUE
Mar	Mark	FALSE
Mar	Jane	TRUE
Mar	Jacob	FALSE
Mar	Steven	TRUE
Mar	Jones	FALSE

Create a measure like this:

PercMeasure: = COUNTROWS(FILTER(Table3, Table3[Rate] = TRUE)) / COUNTROWS(Table3)

As a start this is good, I am getting individual measures correct for each month.

but the grand total is calculating on all rows instead of specific rows.

for e.g. if Month of Feb has all False, filter is still using Feb to divide the grant total. 

Is there any DAX that only calculates the TRUE from each month and returns grand total based on the TRUE found in those months?

Hi @ymirza

 

First of all, my [rate] column is text data type, and then I create a calculated column:

COUNT_TRUE = CALCULATE(
            COUNT(Sheet6[Rate]),
            FILTER(Sheet6,
            Sheet6[Rate]="TRUE"&&
            Sheet6[Month]=EARLIER(Sheet6[Month])))

The same way to calculate the number of months, you can get the rate of each month.

Best Regards,

I don't understand what you mean. Can you give a self calculated example? I looked at your question again and you asked for measure that would work per month, isn't that what you are looking for?

Some of the months are not covered with TRUE statements, that is why the DAX you shared was effective only at individual row level, but not the Grant total. 

What I did using your DAX is created another measure

Total % = IF(HASONEVALUE(Sheet1[Month]),[PercMeasure],   AVERAGEX(VALUES(Sheet1[Month]),[PercMeasure]))
