May I know the formula you’re using for PreviousValue?
On a separate note:
When I apply a date filter range (e.g., 01-Feb-2025 to 28-Feb-2025), I only see the count for the selected date range. However, the previous month’s count is not displayed.
When you filter the visual you loose visibility to the previous period in the visual. To meet your requirement you will have to create two mesaures a) Current Value b. Previous Value which compute the data by filtering dates in the calculation. Don’t filter hte visual itself
Please keep in mind that filtering is by specific dates which could be tricky as in the example above where Feb has 28 dates; previous period is filtering Jan 1 to 28. If you are keen to filter by specific time frames (Week, Month) you can change the parameter to specify start date and Time Frame (Week, Month ) etc and modify the calculated fields accordingly.
