Hi,

Open the presentation tab of your table and select the necessary dimension/expression and select suppress zero-values

Hi,

I've read your post again and understood why you have the issue.

Date(max(DATA_VAL) -1,'YYYYMMDD') always returns the previous date, for this reason, you have 20220327.

You should create DateIndex field in the script based on DATA_VAL field, you can do this with autonumber function, for instance

AutoNumber(DATE_VAL, 'DATE') as DataIndex

Please remember that you should order data in your table in the correct way

After this you will have the following:

DATE_VAL	DAY_NO	DateIndex
3/19/2022	19	1
3/22/2022	22	2
3/24/2022	24	3
3/25/2022	25	4
3/26/2022	26	5
3/28/2022	28	6

max(DATEINDEX) -1 will return data for DATEINDEX 5 - 3/26/2022

max(DATEINDEX) - 4 will return data for DATEINDEX 2 - 3/22/2022

Your expression should be like this:

count({<DataIndex= {"$(=max(DataIndex)-1)"},DAY_NO=>}[Account Number])

Just change vPrevDate to below, to load second latest date

=Date(max(DATE_VAL,2) ,'YYYYMMDD')

Also, if the weekend and holiday dates are still appearing in your charts that means they exist in your dataset

"created a Date script that excludes dayswhere it is Sunday and Public Holiday. Joined the date QVD to base Dataset and now"

I would suggest you do an inner keep or inner join to completely remove weekend/holiday dates from the dataset if you don't need them at all
