$ Difference between MIN and MAX dates

[cbtekrony]

Hello, I am trying to create a card showing the difference in ACV between the MAX date and the MIN date. This is tied to a date filter on a bar graph, so when the user switches years on the graph, the card will reflect the the $ change in ACV and % change (that's for another card later) for the new range of years. So, a simple subtraction calc between the first year and last year selected is what I'm looking for for the $ change. 

However, I cannot get it to work! Here is the sample data I am working with: 

Year	Product Category	ACV
2011	A	$131,282.70
2012	A	$1,397,633.70
2013	A	$2,472,531.60
2014	A	$4,010,372.20
2015	A	$5,295,672.70
2016	A	$6,553,524.60

 I have a date table in place. Tried several things posted before but I'm not getting anywhere.  For example I'm attempting to subtract the ACV from 2012 from the ACV for 2014 to show the total change over time (so not counting 2013). I am not getting the correct value of roughly $2.6m

hi  @cbtekrony 

You could try the logic as below:

Measure = 
var _minyear=MIN('Table'[Year]) 
var _maxyear=MAX('Table'[Year])
return
CALCULATE(SUM('Table'[ACV]),FILTER(ALLEXCEPT('Table','Table'[Product Category]),'Table'[Year]=_maxyear))-CALCULATE(SUM('Table'[ACV]),FILTER(ALLEXCEPT('Table','Table'[Product Category]),'Table'[Year]=_minyear))

Measure 2 = 
var _minyear=MIN('Table'[Year]) 
var _maxyear=MAX('Table'[Year])
return
CALCULATE(SUM('Table'[ACV]),FILTER('Table','Table'[Year]=_maxyear))-CALCULATE(SUM('Table'[ACV]),FILTER('Table','Table'[Year]=_minyear))

 Result:

Try like

measure =
var _max = maxx('Date','Date'[Date])
var _min = Minx('Date','Date'[Date])
return
CALCULATE(SUM(Table[ACV]), FILTER(all('Date'), 'Date'[Date] =_max)) -CALCULATE(SUM(Table[ACV]), FILTER(all('Date'), 'Date'[Date] =_min))
/////////////////////////////////Or

measure =
var _max = maxx('Date','Date'[Date])
var _min = Minx('Date','Date'[Date])
return
CALCULATE(SUM(Table[ACV]), FILTER(all('Date'), year('Date'[Date]) =year(_max))) -CALCULATE(SUM(Table[ACV]), FILTER(all('Date'), year('Date'[Date]) =year(_min)))
