In the Custom Reporst for HubSpot, if you want to look at a property value daily, and for some reason there is no data in some weekday (For example, no data on sundays), the report will show only from monday to saturday and will not show the Sunday bar. I will suggest that the reports start showings all the weekdays including those in which there is not data. Maybe having those days with 0 but showed to maintain a consistent verification.
