The attendance count uses the highest # by any count (moderator, Cvent). Click the Highlight Track box to choose which track to highlight. Notice that there are two tabs at the top, Attendance Grid and Attendance Map. The map allows filtering based on time showing where the attendees were during each session time period. Only times when teaching sessions were being presented are available in the map as all other “sessions” such as the plenaries and the exhibit halls do not make sense to map them (no attendee count, everyone in one place, etc).
