6.4 Timeline view toolbar
ARM Streamline provides easy ways to navigate and modify the Timeline view using the toolbar.
The toolbar controls in the Timeline are:
- Events-Based sampling tag
- If the report was generated using event-base sampling, a label appears in
the far left of the toolbar.

- Toggle bookmark markers
- Activates or deactivates the bookmark markers in the Timeline view. If selected, Streamline
places vertical lines that stretch across the charts and processes sections
under each of your bookmarks.
- Toggle HUD Display
- Toggles the Samples HUD on and off.
- X-Ray mode
- Toggles x-ray mode on and off. When on, Streamline replaces the heat map in
the Processes section with a color-coded map that shows which core or
bigLITTLE cluster spent more time on a process or thread in the given
increment. Blue in the Processes section means the first processor spent the
most cycles, while turquoise indicates that the second processor did. Amber
represents the third core and purple the fourth. There is a color legend in
the bottom left of the Timeline view when X-Ray mode is enabled. In a single
core system, all active areas in the Processes section are blue. Hover over
a color in the processes for a tooltip that tells you which core the color

- Select Annotation log...
- Opens the Log view and selects the closest Annotation-generated message to the current

- Enables you to cycle through the levels of zoom. Use the plus and minus
buttons to increase or decrease the units of time used to represent one bin
in the Timeline view.

- Time index marker
- Shows the time index of the current location of the mouse cursor. The time
index marker contains a drop down menu that enables you to specify the level
of zoom for the Timeline view.
- Filter process
- Enter a regular expression in the field to filter the processes in the
processes section of the Timeline view. For example, if you enter a standard
string consisting only of letters, the processes section updates to include
only [idle], [kernel], and any processes that contain the entered string.
Regular expression strings are case sensitive unless you include (?i) in
front of your search expression. The charts in the Timeline view update to
display only activity from the remaining processes.
- Export Timeline view to a text file
- Opens the export dialog box, enabling you to export the data from the
Timeline view. Values can be separated by spaces, commas, or tab delimiters,
making it easy to save data as a separate file or to open it in your
favorite spreadsheet application.
