Conditional formatting matrix: Comparing cells to adjacent value

[Sweet-T]

Hello everyone - 

I'd like to conditionally format the cells of a matrix to indicate whether or not sales are trending up or down, compared to the previous time period. I say time period, because I would like this to update as I "drill-down" from Year > Quarter > Month.

Additionally, I don't want a simple binary response - ie. "are sales greater or smaller than the previous time period". Ideally, I'd like a colour gradient that reflects the magnitude of the difference between time periods. 

I feel as thought this is feasible using the conditional formatting optoins, but can't seem to get my head around how to construct the Field (assuming a Measure) I need.

Will add some images of my data and some examples of how I'd like the colours (not a gradient), having issues right now.

hi, @Sweet-T

I continue to work on this requirement, and today I find a way may achieve your requirement.

Sorry about my carelessness.

Now, this is a new way for you refer to;

basic data

Step1:

Add a Year Quarter Number column

Year Quarter Number = YEAR ( Table1[Date] ) * 100 + INT ( FORMAT ( [Date], "q") ) 

Step2:

Add this measure

%change = 
VAR previousDate =
    CALCULATE (
        MAX ( Table1[Date] ),
        FILTER (
            ALLSELECTED ( Table1 ),
            Table1[Qty] > 0
                && Table1[Date] < MAX ( Table1[Date] )
        )
    )
VAR previousYQ =
    CALCULATE (
        MAX ( Table1[Year Quarter Number] ),
        FILTER (
            ALLSELECTED ( Table1 ),
            Table1[Qty] > 0
                && Table1[Year Quarter Number] < MAX ( Table1[Year Quarter Number] )
        )
    )
VAR previousREG =
    CALCULATE (
        SUM ( Table1[Qty] ),
        FILTER ( ALLSELECTED ( Table1 ), Table1[Date] = previousDate )
    )
VAR previousYQTOTAL =
    CALCULATE (
        SUM ( Table1[Qty] ),
        FILTER ( ALLSELECTED ( Table1 ), Table1[Year Quarter Number] = previousYQ )
    )
VAR previousQty =
    IF (
        ISFILTERED ( Table1[Date].[Quarter] ),
        previousYQTOTAL,
        IF ( ISFILTERED ( Table1[Date].[Month] ), previousREG )
    )
RETURN
    DIVIDE ( SUM ( Table1[Qty] ) - previousQty, previousQty, 0 )

Step3:

Add Conditional formatting for matrix

Result:

Lin, THANK YOU! 

This is really cool, I apprecaite you taking the time to figure this out. This is a great base; I simplified my model for the sake of explaining my need. I will take what you have given me and try it this weekend, then report back. 

Thanks again,

hi, @Sweet-T

For your first requirement, it can be achieved by adding a measure like: PREVIOUSMONTH Function/PREVIOUSQUARTER Function/PREVIOUSYEAR Function then set Conditional formatting like it.

for example:

Qty QoQ% = 
IF (
    ISBLANK ( CALCULATE ( SUM ( Table1[Qty] ), PREVIOUSQUARTER ( 'Date'[Date] ) ) ),
    BLANK (),
    CALCULATE ( SUM ( Table1[Qty] ) )
        - CALCULATE ( SUM ( Table1[Qty] ), PREVIOUSQUARTER ( 'Date'[Date] ) )
)

It works well.

Best Regards,

I'd first like the formatting to occur quarterly

And to update accordingly when I drill down to monthly
