Patterned on the Program Overview, this plugin provides a pair of sidebars for the Dynamic Listing that indicate the history of the current trace, similar to those in the Time and Memview plugins. The Trace Overview bar gives a compressed view of various events (thread creation/destruction, module loads/unloads, et cetera). Events are added in time snap order without spaces between consecutive events, as in the Memview display. The Trace Selection sidebar allows the user to click & drag over a section of either sidebar and zooms in on that time span. In the zoomed version, events are in snap order with intervening space to indicate the actual time delays (although these are dictated, in part, by the numbering schema for events).
Clicking and dragging over a region of the Trace Overview causes that span to be displayed uncompressed in the Trace Selection. The same action can also be applied to the Trace Selection itself, resulting in a more detailed zoom.
Shift click & drag on the Trace Selection allows the user to move forward and backward in the view without rescaling.
