## Top N / Rank for a specific month and return the last 12 month value for those Top N

Hi folks,

I need to build a line chart where I need to 1. find the top 10 brands (legend) of the brand share (Y axis) for the current month. 2. Return the last 12 months (X axis) brand share for those top 10 brands identified in step 1.

(Don't worry about the last 12 months, I can use filter to mannually select the 12 months)

I have no clue what function I should use. Rank or Related or others?

For now, I'm able to build the chart using top N as a filter for the legend. However this approach returned the top 10 brands based on the average brand share for the last 12 months, not the current month's brand share.

Hi @thisiskl ,

Here I create a sample to show you how to achieve your goal. If you want to get dynamic Top N, you can create a what if parameter for slicer.

My Data model:

Then create a measure as below.

``````Top N Brand Value =
VAR _TopN =
SELECTEDVALUE ( 'Top N'[Top N] )
VAR _SUMMARIZE =
SUMMARIZE (
ALL ( 'Table' ),
[Brands],
"CurrentMonth",
CALCULATE (
SUM ( 'Table'[Value] ),
FILTER (
'Calendar',
YEAR ( [Date] ) * 100
+ MONTH ( [Date] )
= YEAR ( TODAY () ) * 100
+ MONTH ( TODAY () )
)
)
)
_SUMMARIZE,
"Rank", RANKX ( _SUMMARIZE, [CurrentMonth],, DESC, DENSE )
)
VAR _RANK =
SUMX ( FILTER ( _ADDRANK, [Brands] = MAX ( 'Table'[Brands] ) ), [Rank] )
RETURN
CALCULATE ( SUM ( 'Table'[Value] ), FILTER ( 'Table', _RANK <= _TopN ) )``````

To show last 12 months data, you can use relative data function in filter field. Result is as below.

This solution is awesome!

It works perfect for my case. I have a few filters, so I changed TODAY() to MAX(calendar[dt]) , ALL() to ALLSELECTED().
