Conditional Formatting basede on previous values the Matrix columns

Hi, can someone tell me if we can format the values of the Matrix as required:

The Icon un each row depends of value on the previous column on that same row.

You can create this measure:

Icon =
VAR _val =
 CALCULATE ( SUM (  Sales[Sales] ) ) 
-
 CALCULATE (  SUM ( Sales[Sales] ),
        PREVIOUSMONTH ( 'DateTime'[Date] )    )
        
RETURN
    SWITCH ( TRUE (),
   _val < 0, -1, 
   _val = 0, 0,
   _val > 0, 1 )

Change the RED to match your columns!

Then, on your matrix, go to the format properties.
Under conditional formatting, select the column and turn on icons, then click advanced editor:

In advanced controls, select the following options:

Hi SteveCampbell

How does this work for colums with weeknumbers? There is no "previousweek" formula in PBI 😞

I use this formula:

Icon =

VAR _val =

CALCULATE ( SUM ( Datagrunnlag[Antall solgt]) )

CALCULATE ( SUM ( Datagrunnlag[Antall solgt] ),

Dates[Weeknumber]-1)

RETURN

SWITCH ( TRUE (),

_val < 0, -1,

_val = 0, 0,

_val > 0, 1 )

See screenshot

Use a date table with an index (Example here)

The week index is rolling, with current week being 0, last week -1 and so on. So whatever week you need, you can get the week index and subtract 1 to always get the previous. This way, it doesn't matter if you week falls in a different year.

You need to assign this to a variable and filter the dates table on it:

Icon = VAR _lastweek = SELECTEDVALUE('Dates'[week index]) - 1 VAR _val = CALCULATE ( SUM ( Datagrunnlag[Antall solgt]) ) - CALCULATE ( SUM ( Datagrunnlag[Antall solgt] ), Dates[week index] = _lastweek ) RETURN SWITCH ( TRUE (), _val < 0, -1, _val = 0, 0, _val > 0, 1 )

Is there a way to do this comparison against the previous week instead of the previous month?

I noticed there is no PREVIOUSWEEK() function...

Thanks!

Hi - when I follow this solution all my formatting is returning an increase from the previous month - even when there's a decrease in value. I added the measure to a matrix and all the values are 1.

My date field is in Date format and I've also tried when set to DateTime.
Can you help please?

Many thanks
