Prev Value if Blank

Hi, I have this cumulative calculation with the x axis being a month. If I don't have a value in one month, my line breaks. Any idea how to amend the existing logic so it pulls previous value is there's a blank? 

 

 

Val =

calculate

(sum(test_val),

filter(

Allselected (test),

test[test_date] <= max (test[test_date])),

groupby (test, test[test_year]))

Hi,

Try this approach

  1. Create a Calendar Table with calculated column formulas for Year, Month name and Month number
  2. Sort the Month name column by the Month number column
  3. Create a relationship (Many to One and Single) from the test_date column to the Date column of the Calendar Table
  4. To yoru visual, drag Year and Month name from the Calendar Table
  5. Write these measures

Total = sum(test[test_val])

Total YTD = calculate([Total],datesytd(calendar[date],"31/12"))

If you want the accomulation since the inception, then write this measure

Total since inception = calculate([total],datesbetween(calendar[date],minx(all(calendar),[Calendar[date]),max(calendar[date])))

Hope this helps.

Hi @M_SBS_6 ,

You can try this DAX:

Val = 
VAR CurrentDate = MAX(test[test_date])
VAR PreviousValue = CALCULATE(
    SUM(test[test_val]),
    FILTER(
        ALLSELECTED(test),
        test[test_date] < CurrentDate
    ),
    GROUPBY(test, test[test_year]),
    LASTNONBLANK(test[test_date], CALCULATE(SUM(test[test_val])))
)
VAR CurrentValue = CALCULATE(
    SUM(test[test_val]),
    FILTER(
        ALLSELECTED(test),
        test[test_date] <= CurrentDate
    ),
    GROUPBY(test, test[test_year])
)
RETURN IF(ISBLANK(CurrentValue), PreviousValue, CurrentValue)

Best Regards,
