The Counter Timeline shows the values of all counters that a given trace file provides. The Intel® Trace Collector records user-defined counters or counters provided by the operating system. See the Intel® Trace Collector User and Reference Guide to learn more about tracing counters.

| Element: | Description: |
|---|---|
| Line segments | Connect sample points for counters with the Curve attribute |
| Markers | Show sample points with the Valid AT point attribute |
| Short unconnected horizontal line segments | Show counter samples with other scopes |
| Status bar at the bottom of the panel | If the mouse pointer is near a sample point, then its exact position in time is shown. |
There are no markers anymore because the values shown represent samples that were merged over time. To force that effect the View was made very narrow.
