## Populate collection with missing days/dates

Hello Everyone,

If I have a collection with some data:

```Date               x  y   z

01/09/2019  15 32 16

02/09/2019  15  0   12

05/09/2019   1   3    0

15/09/2019   0   1    0

25/09/2019   0   0    55```

How would you fill all the missing dates with 0  0 0 value to obtain something like :

```Date               x  y   z

01/09/2019  15 32 16

02/09/2019  15  0   12

03/09/2019   0   0    0

04/09/2019   0   0    0

05/09/2019   1   3    0

06/09/2019   0   0    0

....

15/09/2019   0   1    0

16/09/2019   0   0    0

....

25/09/2019   0   0    55

....

30/09/2019   0   0    0

```

Or would you do it another way?

The goal is to have a gallery with every day of the selected month, with data coming from another data source.

Cheers

Hi @HD

Considering you want to do this for current month, please use the expression:

ForAll(FirstN([0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30],DateDiff(Date(Year(Today()), Month(Today()), 1),Date(Year(Today()), Month(Today()) + 1, 1))),If(!(Text(Date(Year(Today()), Month(Today()), 1+Value),"[\$-en-US]dd/mm/yyyy") in testcol1.Date),Collect(testcol1,{Date:Text(Date(Year(Today()), Month(Today()), 1+Value),"[\$-en-US]dd/mm/yyyy"),A:0,B:0,C:0})))

This will update the existing collection with the 0 value for dates that does not exist. Here, testcol1 is the name of my collection.

Hope this Helps!
