Date issue

Anku — Thu, 04 Nov 2021 07:45:54 GMT

Hi all,

I am creating a line chart, refer below.

As you can see it's not following the expected pattern.

I have also used date(date#(datadate,'dd-mmm-yyyy'),'mmm d').

Please suggest how to fix this discrepancy.

Note: measure : sum(sales)

Thank you.

Hi, thats the null values, those are records with values on sales fields that doesn't has any relation with the datadate field.

You can add a table with datadate as dimesnion ans sum(sales) as expression, and add some dimesnions to check where those values come from and why they don't have a date associated.

@rubenmarin

Yes, I tried to figure out but unable to get a solution. I have attached the dummy data. Kindly assist and share your feedback. Thanks!

Please note, It's a dummy data with the similar issue.

Hi, it's a format issue, your date field in the sales table has a DD/MM/YYYY format , and it's a date, (by default rigth aligned), the date field in the calendar is in DD/MMM/YYYY format and it's a string (by default left aligned).

I switched the name of the dates and date fields in the calendar and it seems to work. Also added a new script sheet using a master calendr to avoid that you have to write each day.

There are still some values with null, it's because of this expression:

If(DayNumberOfYear(Today(1))>DayNumberOfYear(Date)
,Dual(Date(Date,'MMM D'),DayNumberOfYear(Date))
,Null()) as YearDayNoYTD // Number of days above today will get null()

If you don't want to show this values, expand the YearDayNoYTD dimension and uncheck the option to show null values.
