The Activity Log is available to MyKeynote users with administrative privileges. It shows all graphing activity for your login over the last 7 days (the last 24 x 7 hours ending at the current time). There is one entry for each measurement graphed per day. The Count column shows the number of times you have graphed a measurement in a given day. The total number of graphs generated over the last 7 days is shown at the bottom of the table.
