I have this measure, its for 12 months only Apr to March. Can someone help me with adjusting it so that it rolls on to how ever many months are in my table?
Hi @lennox25 ,
Based on the description, try to use the following DAX formula to calculate std.
Std dev2 =
VAR CurrentDate = MAX('Date_Dim'[MonthYearInt])
VAR MonthsBack = 12
VAR StartDate = EDATE(CurrentDate, -MonthsBack + 1)
RETURN
CALCULATE(
STDEV.P('Date_Dim'[Total_Sales_only]),
FILTER(
ALL('Date_Dim'[MonthYearInt]),
'Date_Dim'[MonthYearInt] >= StartDate && 'Date_Dim'[MonthYearInt] <= CurrentDate
)
)
Best Regards,
Wisdom Wu

hi @v-jiewu-msft I appreciate the work that you have put in here, but I need the std d to be the same month on month - with my neasure above, I can only acheive the following. As you can see its only doing STD D to each financial year I need it to be the same month on month.
Hi @lennox25 - Try like below with min and max on month year field. if not works , Can you share sample data Or a sample pbix after removing sensitive data.
Std dev =
VAR InitialDate =
MIN('month avg'[Month Year])
VAR FinalDate =
MAX('month avg'[Month Year])
RETURN
CALCULATE(
STDEV.P('month avg'[Total Sales Per Month]),
ALLSELECTED('month avg'[Month Year]),
DATESBETWEEN(
'month avg'[Month Year],
InitialDate,
FinalDate
)
)

Hi @rajendraongole1 , Your calculation is Std Dev 2 - it has had strange results. Heres my sample data.
Can you please copy and paste the text here? with expected result

OK, ignore the prrevious example. I will use my excel example. I can use a separate date table if that helps (which is Date_Dim) or I have added in PBI a date table to my sales table.
Hi - Expecting the input should be copy and paste as like below:
Date Dim(MonthYear) | 4/23 | 5/23 | 6/23 | 7/23 | 8/23 | 9/23 | 10/23 | 11/23 | 12/23 | 1/24
Please share the inputs as like above for easy copy text. |
