To change the colors of the functions, messages or collective operations, use the
three Colors buttons at the bottom of the Settings dialog box. Function Colors
call up the Function Group Color Editor (the section called “The Function Group
Color Editor”). To change the color in which the messages are displayed, click on
the Message Color button. This opens a dialog box where the required color is
chosen. Change the color of the Collective Operations in the same way if need be.
Colors chosen for messages and collectives are local to the Event Timeline Chart.
Colors chosen for functions or function groups are shared by all Charts and Views
belonging to the same trace file.
The Context Menu
Apart from the general options common to all Charts (see the section called
“Common Chart Features”), the context menu of the Event Timeline provides
details pertaining to the function, the message or the Collective Operation. For
example, to access details about a particular message in the Event Timeline,
right-click on the message and select the option Details on Message. This opens
a new dialog box displaying information on sender, receiver and other message
attributes. This is further explained in the section called “The Details Dialog”.
When invoked for a collective operation the context menu will offer the entry
Zoom to Collective that will set the View's time interval to the time covered by
the respective collective operation.

Furthermore, the context menu has an entry to ungroup/regroup the function,
which works the same way in every Chart. To display functions, messages and/
or collective operations, select Show from the context menu. Select/deselect one
or more of the above from the sub-menu that opens on clicking Show.
