How to show all the dates?

Irwan  Thank you for the response, I've got this filter set up for August, but there are a couple of days missing - like the 20th and the 22nd because there's no data for those days. The thing is, when I use your method to show items with no data, it just throws away the filter and shows me everything, all the dates, and I just want to see what's happening this month. I am not sure why it does ignore the current month's filter
