Use tagging in the Qualitative Timeline to find specific events that occur infrequently. You can find these events because a grouped multiple event is tagged if at least one of the singular events it represents matches the tagging filter expression.
Tagged items in the Qualitative Timeline are highlighted with red.
For example, to tag all messages sent by P3 and P13, do the following:
Open the Tagging dialog box and go to the Messages tab.
In the group Messages to be Tagged, select the radio button Custom.
Specify whatever needs to be tagged in the given field, for example P3, P13.
When you tag messages in Processes 3,13 in Qualitative Timeline, the result looks similar to:
When you filter the Qualitative Timeline for a particular event, you see only this event, since only this event passes the filter and all the other events are filtered out.
For example, to filter out all messages except those sent by P3 and P13, use the Filtering Dialog Box.
