The Timeline options dialog box allows you to select what you want displayed on the Timeline tab. It allows you to select to either show or hide events that have no latitude and longitude and therefore cannot be displayed on the map. It also allows you to select to either display the time line events from the CDR files, phone data files and target locations or to display only the time line events from the phone data files.
NOTE: Events must have a time associated with them for them to appear on the Timeline tab. Data in the CDR files always as a time associated with it but some data in the phone data files does not. Target locations can have a time associated with them if you set the target location's start or end time on the Locations of interest screen (Case management).
