Helper I

## Average or relative weeks

Hello,

I am looking for a way to stabilise the rate fluctuations on the graph (see pic below).

As you can see the graph shows rates for the past 12 weeks (purple line). I am using relative weeks in my date helper to visualise this so in my filter I have set to show relative weeks from -1, -2, -3 all up to -12.

In order to "stabilise" the rates so that there is not this much fluctuation, I would like to average the rates.

This means that for week 24 I would like to show a number that's the average of the past 12 weeks (week 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14 and 13).
For week 23 I would like to show the average of week 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13 and 12.

For week 22 and the rest of the weeks the same pattern as above...

Thank you!

Hi @n5722 ,

Please try to create a measure like below:

``````Measure =
var current_week = SELECTEDVALUE(Sheet3[week])
return
CALCULATE(
AVERAGE(Sheet3[rates]),
FILTER(ALL(Sheet3),
Sheet3[week]>=current_week-12&&
Sheet3[week]<=current_week))``````

@V-lianl-msft Thank you very much for this! It worked like a charm 😁

@n5722 , Try a measure like

Last 12 weeks = CALCULATE(averageX(values('Date'[Week]), [Actual]), FILTER(ALL('Date'),'Date'[Week Rank]>=max('Date'[Week Rank])-12 && 'Date'[Week Rank]<=max('Date'[Week Rank])))

These column in date table

new columns
Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)
OR
Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format

Hi @amitchandak. Thank you very much for your reply but unfortunately, this did not work out for me.

Maybe it might help if I attach the date helper table overview for your convenience.

Here is an overview of it.
