Understanding the timeline chart
Event information in the Related Event Details portlet is available in chart format.
You can use the Related Event Details portlet to view more information about related events. For example, you can view charted event information on a timeline chart. For more information about how to view the charted event information, see Switching between tabulated and charted event information
The timeline chart shows the event distribution for each event type in the group, relative to the pivot event. The pivot event is always at zero seconds, minutes, or hours.
Each comb in the timeline chart represents an event type and the teeth represent the number of instances of the event type. The blue event markers represent all the times the event occurred relative to the pivot event. The red event markers indicate the time that the event occurred in the selected group instance.
