ResSched lets users choose whether they want to view graphical scans in vertical (resources across the top; date/time down), horizontal (resources down the left of the window; time across the top), calendar (standard monthly calendar).  While the choice is largely a matter of user preference, there are important functional differences. The vertical format can usually provide more space for booking descriptions, but does not display double bookings or bookings of pooled resources well.  The horizontal format displays these types of bookings well, but there is often less space available for text descriptions of the booking.   The calendar format is not suitable if there are large numbers of bookings on any day.
