Showing relative past 30 days with Rolling Averages (quick measures)

[RogerSteinberg]

Hello PowerBI community,

I would like to replicate common financial line graphs to show the past 30 or 60 days using the 15, 30 day rolling averages as trends.

It seems however the visuals can't display moving averages along with relative days filtering.

Examples of these charts can be found in yahoo.finance.

Thank you.

hi, @RogerSteinberg

Based on my test, You could do some optimization on quick measure formula as below:

Qty rolling average = 
IF(
	ISFILTERED('Date'[Date]),
	ERROR("Time intelligence quick measures can only be grouped or filtered by the Power BI-provided date hierarchy or primary date column."),
	VAR __LAST_DATE = LASTDATE('Date'[Date].[Date])
	RETURN
		AVERAGEX(
			DATESBETWEEN('Date'[Date].[Date], DATEADD(__LAST_DATE, -15, DAY), __LAST_DATE),
			CALCULATE(SUM('Table3'[Qty]))
		)
)

Delete the red font section

new Qty rolling average = 

	VAR __LAST_DATE = LASTDATE('Date'[Date])
	RETURN
		AVERAGEX(
			DATESBETWEEN('Date'[Date].[Date], DATEADD(__LAST_DATE, -15, DAY), __LAST_DATE),
			CALCULATE(SUM('Table3'[Qty]))
		)

Now you can use relative days filtering

Best Regards,
