How do you compare DAY of Week - Week over Week?
Hi all,
I am looking for a way to be able to compare each day of week separately week over week. For example Thursday 9/8, Thursday 9/15, Thursday 9/22, etc. I want to be able to get show totals for this.
I am working with call center data and I'd like to analyze call drivers based off of the day of week to understand where things are trending.
I have a date table that contains, Date (obviously), month, year, month num, Day of week, Day of week num, etc etc. Basically any date dimension you'd usually have, I have in my model.
I've never had an ask to seperatly compare the progression of the same day of week. Has anyone done this before? How would I even do this? I'm having a hard time wrapping my head around this.

Create a calandat table with:-
- date
- day of week (mon, tue, wed, thurs, fri, sat, sun)
- week commencing date
Build a relationship calendar[date] 1:M to calls[date]
Create a measure
Total calls = SUM(calls[amount])
Draw a line graph for Total calls by week commencing date.
Note this will show the total sales per week.
Then comes the clever bit ....
add a single slection slicer for day of week
If you slice Thursday then the line graph will show the trend for Thusday,
If you slice Sunday then the line graph will show the trend for Sunday. 😀😀😀

Okay so I'm thinking I may have not explained this correctly.
I don't want to get totals for that week.
I want to compare this Monday to last Monday. Meaning, I don't care about the totals for the whole week. I just want to figure out that specific day of week. I'd like to do this for all days of week.
I could just use a date column and manually filter the dates to what I want them to be, but that's really not what I want.
I'd like to be able to automagically have a comparison visualization for all days of week individually.
Hi whatisdata96
Okay, actually you have explained this correctly ... but you not understood how to use the 2 good solutions offered by solvers 😀😀😀
Let me try explain better ...
Create calendar table with 1:M relationship to your fact tabels dates
Learn how here Calendar Table training
Then add a day name column (not measure) to your calandar table
Day name = FORMAT('Calendar'[Date],"ddd")Then creates measure (not columns) for each dayMon sales = CALCULATE([Total sales], 'Calendar'[Day name] = "Mon")Tue sales = CALCULATE([Total sales], 'Calendar'[Day name] = "Tue")Wed sales = CALCULATE([Total sales], 'Calendar'[Day name] = "Wed")etcand plots them on graph
Hi, whatisdata96
Add a new column of weeks to the date table.
Column:
Weekday = WEEKDAY([Date],2)Sample data:
The comparison of Thursdays can be obtained through the slicer.
Is this the result you expect?

Day name = FORMAT('Calendar'[Date],"ddd")Then create this measure (not a column)Total sales = SUM(Sales[Amount])And plot a line graph by month by DAY nameor a line graph by week by DAY nameor a line graph by quater by DAY nameall these options will allow to see the trend and easily spot any outliersThanks for reaching out for help.
