In the
Characteristic Filter region, you can hide
sub-items in order to filter out alarms, making only the alarms you want to
focus on visible on the timeline.
Expand the alarm characteristic you want to filter on to see the
sub-items of that characteristic.
Right-click on a sub-item and select
Hide Selected or
Hide Unselected in the context menu.
To bring all the sub-items back into view, right-click on the
alarm characteristic and select
Show All.
Note
When a sub-item is selected, all of the alarms matching that
sub-item's characteristic are highlighted in the Timeline Chart region and
Alarm List. The selected alarms' corresponding events are also highlighted in
the Control Actions list.
