Average for week

Hello,

I am trying to create a column that will find the average weekly sum, from Monday thru Sunday.

 

For example, for every [Date] record that contains Feb 1, it would show the average of all [Value] from Feb 1-7. For every [Date] record that contains Feb 5, it would also show the average of all [Value] Feb 1-7. Any [Date] record from Feb 8 thru 14 will show the average [Value] sum from Feb 8 thru 14.

Hi @patri0t82 ,

 

You will need to create a week column on Daily Force Report.

week = WEEKNUM('Daily Force Report'[Date],2)

Then create a measure or column using ALLEXCEPT() function as below.

Column = CALCULATE(SUM('Daily Force Report'[Total - Total_]),ALLEXCEPT('Daily Force Report','Daily Force Report'[week]))/CALCULATE(DISTINCTCOUNT('Daily Force Report'[Date]),ALLEXCEPT('Daily Force Report','Daily Force Report'[week]))

 Result would be shown as below.

Thank you for your support. When I use the columns you've created (in the visualization you'll see I've called your "column" "average", it appears like this in my chart:

Unfortunately it's not quite what I was hoping for. Though the light blue bars are straight across showing the average for the week, the number shown is incorrect. The average for the first week should be 150.8 (754 / 5). Furthermore, it still remains unaffected by selecting Days/Nights.

I have been able to to adjust my source to only include weekdays, so the average per week is showing at 150 for the first week, as desired. The only other problem with this calculated column:

Average =
CALCULATE(SUM('Daily Force Report (Site Resource Forecast)'[Total - Total_]),
ALLEXCEPT('Daily Force Report (Site Resource Forecast)','Daily Force Report (Site Resource Forecast)'[Week]))
/
CALCULATE(DISTINCTCOUNT('Daily Force Report (Site Resource Forecast)'[Date]),
ALLEXCEPT('Daily Force Report (Site Resource Forecast)','Daily Force Report (Site Resource Forecast)'[Week]))
 
is that it doesn't respond to Days/Nights, which is a must have, if possible. Any help is greatly appreciated.

 

Hi @patri0t82 ,

 

If you want the value be affacted by days/nights slicer, you will need to add FILTER() function in the formula, like:

calculate(avg(xxx),filter(allexcept(table,column),days/nights=selectedvalue(days/night)))

Thank you for the response - I've transformed your code into this below, though it returns blank values.

 

Average =
CALCULATE(
AVERAGE('Daily Force Report (Site Resource Forecast)'[Total - Total_]),
FILTER(
ALLEXCEPT('Daily Force Report (Site Resource Forecast)','Daily Force Report (Site Resource Forecast)'[Week]),[Days/Nights] =
SELECTEDVALUE('Daily Force Report (Site Resource Forecast)'[Days/Nights])))
 
At the very least there are no error messages. Thank you for your continued help. Hopefully we're really close.
To be clear, for each row that shows Days in the [Days/Nights] column Week 6 should show 135.4. For each Nights for week 6 it should be 15.4, the total average for week 6 should be 150.8

I've JUST ABOUT got the result I need, but it doesn't show up in the visualization properly.

The code for my column is:

Average3 =
CALCULATE(
SUM('Daily Force Report (Site Resource Forecast)'[Total - Total_]),
FILTER(
ALLEXCEPT('Daily Force Report (Site Resource Forecast)','Daily Force Report (Site Resource Forecast)'[Week]),
[Days/Nights] = EARLIER('Daily Force Report (Site Resource Forecast)'[Days/Nights])))/5

 

Correct.png

 

The correct numbers of 15.4 (Nights) and 135.4 (Days) are showing up for Week 6, HOWEVER, when I add this to the visualization, the numbers appear SUM into the thousands. I just need 15.4, 135.4 and 150.8 to show up for each day of that week. Not the sum of all of them.

 

Can somebody please lend their expertise. Thank you so much.

Hello,

I've attempted to use the information above with limited success. I've added an Excel workbook which provides the two datasets I'm attempting to combine and a picture to show current status.

 

The dark blue represents Site Resource Forecast whether it be Day/Night or Total

The green represents Force Reporting totals from Monday - Friday, filterable on Day/Night

What I'm looking for is a third measure that will tell me the average total of the green bars in a straight line, week by week.

In the image below, for example, from 2/1/2021 - 2/8/2021, the new bar or line will show 150.8 (or 151) for every day of that week. When I click on Days or Nights (as seen in the second image), the average for the first week should show 15.4 (or 15) for every day of that week.

Thank  you for your response.

I have added a column to my table CalendarTable:

Week Start date(Mon-Sun) = CalendarTable[Date]+-1*WEEKDAY(CalendarTable[Date],2)+1

The column appears to show the ideal outcome.

With that said, when I create my measure:
Measure = AVERAGEX(Values(CalendarTable[Week Start date(Mon-Sun)]), CALCULATE(SUM('Daily Force Report'[Total - Total_])))
and use it in a visualization, it returns the same values as 'Daily Force Report'[Total - Total_)

Can you tell if I'm doing something wrong? As far as relationships, I currently have CalendarTable[Date] pointing one way toward 'Daily Force Report'[Date]. I tried setting it to both, but it made no difference.
