Group by date & filter
Hello everyone,
I am new using Power Bi Desktop and am struggling with something...
I have imported a database from SQL table :
Each line corresponds to the detection of a car 1way/ car 2nd way/bike/truck/pedestrians
I am now trying to display the average number of total cars+trucks, filtered by day, filtered by zone (cameraID).
The idea would be to display an "average number of cars+trucks per day in february in zone 4" for example.
I tryed using the group by function to make a new table with merged dates but can't make it work because of the differences between zones and type of detection.
Any idea how to solve this problem please ?
Kind regards,
Antoine
So, use slicers for what you want to filter on. Then you need a Date column with Date and no timestamp or Date and the same timestamp. Then you should be able to use SUMMARIZE like:
Average Measure = VAR __Table = SUMMARIZE( 'Table', [Date no Timestamp], "Count",COUNTROWS('Table') ) RETURN AVERAGEX(__Table,[Count])
