Getting Min value from Last 4 Quarter graph

[Anonymous]

Hi All, I need help here to solve this issue.

Let me explain the requirement first:

Getting the difference between min value and max value based on filtered graph. Which in my case last 4 quarter.

This graph is shown based on this formula:

Last 4 Quarters Avg Fac ID =

CALCULATE(([Sum CountD Facility ID]/[CountD YearMonth 2]),

FILTER( ALL(DateSelector[YearMonth]),

DATEDIFF(DATE(YEAR(MAX(DateSelector[YearMonth])),MONTH(MAX(DateSelector[YearMonth])),DAY(DateSelector[YearMonth])), DateSelector[YearMonth] ,QUARTER) <=0 && DATEDIFF(DATE(YEAR(MAX(DateSelector[YearMonth])),MONTH(MAX(DateSelector[YearMonth])),DAY(DateSelector[YearMonth])), DateSelector[YearMonth] ,QUARTER) >= -3 ))

For example when i filter sept 18 then the graph will show last four quarter from Sept-18(Like the picture above)

The issue here is I need to do calculation to get the min value of the last 4 quarter which is Q4-2017 value as per the picture. And my max value is Q3-2018. This should always change prior to date filter selected.

The calculation value will be shown in card.

Thank you in advance! 🙂

hi, @Anonymous

This looks like a measure totals problem. Very common. See this post about it here:

In your case, if you change bar chart visual to table visual, you will find the table visual is like this

Quarter	Last 4 Quarters Avg Fac ID
Q4-17	1658
Q1-18	1667
Q2-18	1646
Q3-18	1621
Total	***

Then you use MINX() or MAXX() instead of SUMX() in above post to create a measure to get the min/max value and then drag 

the measure into card visual.

Thanks! It works with the MINX and MAXX
