HELP!! Measure show comparison between selected values and other categories

[jts_]

Hi, I have a simple table that contains state, county, and growth rates.
I need to create a measure in Power BI that allows the visualization would change dynamically for comparison.

In the project scope, there are 3 states in total. I want each state's average growth rate to stay on the visualization all the time.

In addition, if there is a county is being filtered, this measure would return the average growth rate of each state PLUS the growth rate of the selected county.

Below is an example of the data:

State	County_Name	CountyState	GrowthRate
Arkansas	Baxter County	Baxter County Arkansas	2.0%
Arkansas	Ashley County	Ashley County Arkansas	3.0%
Arkansas	Arkansas County	Arkansas County Arkansas	1.5%
Kentucky	Adair County	Adair County Kentucky	1.7%
Kentucky	Allen County	Allen County Kentucky	3.2%
Kentucky	Anderson County	Anderson County Kentucky	6.8%
Virginia	Accomack County	Accomack County Virginia	10.0%
Virginia	Albemarle County	Albemarle County Virginia	0.5%
Virginia	Alleghany County	Alleghany County Virginia	6.0%

If Allen County is filtered, I'd like this measure to show the average rate of each state with Allen County in the comparison.

Arkansas	6.5%
Kentucky	3.9%
Virginia	5.5%
Allen County	3.2%

Thank you in advance!! I appreciate all your insights!

Hi @jts_ ,

Since dynamic tables are not supported in PBI Desktop, your expected result cannot be achieved by presenting the State column and the selected County_Name column on a single column.

(1) My test data is the same as yours.

(2) We create a new table.

Table 2 = 
VALUES('Table'[State])

(3) We can create a measure.

Measure = 
var _rate=CALCULATE(SUM('Table'[GrowthRate]),FILTER(ALL('Table'),'Table'[State]=MAX('Table 2'[State])))
var _rows=COUNTROWS(FILTER(ALL('Table'),'Table'[State]=MAX('Table 2'[State])))
return DIVIDE(_rate,_rows,0)

(4)Then the result is as follows.

@jts_ , You need a disconnected table for that. Assume you have measure m1

then have new measure

m2= calculate([m1], filter(Table, Table[State] in values(State[State]) )

or

m2= calculate([m1], keepvalues( Table[State] in values(State[State]) )
