Open
.
NOTE
The first frame cannot be opened for profiling.

Opens the selected frame in the Profiling View.
Stream Viewer Pane
Timeline
ruler
Correlates all the displayed frames with the timeline. The range of the timeline corresponds to the length of the stream in the current zoom level. Depending on the zoom-in level, the time intervals are displayed in seconds, milliseconds, microseconds, or nanoseconds.
Zoom to Selection

Zooms into the time range of selected frames.
Full Zoom Out
button
Restores the default zoom level.
Context/Queue
bar chart
