Difference in Matrix instead of Total

[Anonymous]

I have problem, but I can't solve it.  I made matrix from table with values for places each year. I get Total in column to right but I need difference between column nr. 2 and 10 and ratio in next column.  I don't find solution for that.

My example in Matrix table

Place           2011       2012...........2019   Total(but I need difference)

East coast     10.605                  11.254    21.859 (649)

How do I solve this?

Best regards,

Hi,

See if this measure helps

=IF(HASONEVALUE(Data[Place]),[your measure],CALCULATE([your measure],LASTDATE(Calendar[Date]))-CALCULATE([your measure],FIRSTDATE(Calendar[Date])))

You shoould have a Calendar Table and an active relationship between the Date column of your Data Table to the Date column of the Calnedar Table.  In the Calendar Table, write this calculated column formula to extract the year

Year = Year(Calendar[Date])

To your visual, drag the Year field from the Calendar Table.

Hope this helps.

Hi Ashish.

Thanks.  I'm new to PBI, and just beginning using DAX.  You write: "You should have a Calendar Table and an active relationship between the Date column...."

I don't know how to create new table (Calendar Table).  Thats my problem (among other things.. 🙂 )

Here is a script to create a datetable.

If you google Power BI Date Table Script you'll get a bunch of different results along with a bunch of videos that will take you step by step.

HI @Anonymous ,

You can use measure formula with if statement to check current row contents level and apply specific calculation formula if they are on total level and use normal summary formula on other levels. (replace original value field)

Measure Totals, The Final Word

After these steps, you can enter to 'subtotals -> column subtotals label' to custom the total level label.
