How to write measure to get count of blank value for particular date?

Hi Experts,

Suppose I have below table in which I have some missing value on few days.
                   

Day               Value
day1                 3
day2
day3
day4
day5
day6
day7                  8
day8                  7
day9                  8
day10
day11
day12                 9

As we see above we have 5 day missing value from day 2 to day 6 and 2 day missing from day 9 to day 12.Need to get count of blank space on particular day.

Day       Value         Expected value
day1        3                   3
day2                             5
day3                             5
day4                             5
day5                             5
day6                             5
day7           8                8
day8           7                7
day9           8                8
day10                           2
day11                           2

day12        9                 9

Source table "Count of Blank"

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("bc/BCcAwCIXhXTwHoqZp4izB/ddoa2rp4YH/5UME1yKrUpWVqVCLvDyoiff01xqwA1gHdgIbaTPaOBNHtNHQpvDvpiYKwu8bi9wv", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Day = _t, Value = _t, #"Expected value" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Value", Int64.Type}, {"Expected value", Int64.Type}, {"Day", type date}})
in
    #"Changed Type"

 

Measure:

CountBlank := 
var d = SELECTEDVALUE('Count of Blank'[Day])
var v = SELECTEDVALUE('Count of Blank'[Value])
var cs = CALCULATE(max('Count of Blank'[Day]),'Count of Blank'[Value]<>BLANK(),'Count of Blank'[Day]<=d,ALLSELECTED('Count of Blank'))
var cf = CALCULATE(min('Count of Blank'[Day]),'Count of Blank'[Value]<>BLANK(),'Count of Blank'[Day]>=d,ALLSELECTED('Count of Blank'))
return if (ISBLANK(v),DATEDIFF(cs,cf,DAY)-1,v)

 

Result:

Hi,

Try this calculated column formula

=if(Data[Value]=BLANK(),CALCULATE(min(Data[Day]),FILTER(Data,Data[Value]>0&&Data[Day]>EARLIER([Day])))-(CALCULATE(MAX(Data[Day]),FILTER(Data,Data[Value]>0&&Data[Day]<EARLIER([Day])))+1),Data[Value])

Hope this helps.

Hi,

In the Day column, do you have Day1, Day2 or do you have a proper date entry?  Please clarify.

You need a sortable column for that. Your example Day column is not working for that sort.  Is it really in that format or do you have actual dates?

 

You can then use FIRSTNONBLANK and LASTNONBLANK to find the boundaries of your gaps etc.
