Conditional Formatting based on previous Value

Hi Anonymous 

I did an example for 1 column.
Create 2 new columns:

Previous Month Tickets =
VAR prev_month =
    PREVIOUSMONTH ( T13[MONTH] )
RETURN
    IF (
        CALCULATE (
            SUM ( T13[TICKETS UPDATED #] ),
            FILTER (
                T13,
                prev_month = T13[MONTH]
            )
        )
            = BLANK (),
        0,
        CALCULATE (
            SUM ( T13[TICKETS UPDATED #] ),
            FILTER (
                T13,
                prev_month = T13[MONTH]
            )
        )
    )

Colors =
IF (
    T13[TICKETS UPDATED #] > T13[Previous Month Tickets],
    "GREEN",
    "RED"
)

Then format according to field value

Cheers!
