The Task Groups panel displays the entire list of all task groups in a bar chart with the height of each bar representing the duration of the task group. This panel only is available if task groups are present in the workload. It is not shown by default but can be made visible through the Panels Menu.
By default, the bar chart sorts tasks’ groups along the X axis by the “sequence number” parameter, and draws the bar heights to indicate the overall serialized duration of the tasks associated with the tasks’ group for that bar.
Selected tasks’ groups are highlighted in yellow. The selection in the Task Groups chart is synchronized with the selection in the timeline and other panels.
The Task Groups panel includes the following UI controls:
Display… A multi-selection combo box containing the tasks’ group categories instrumented in the trace file. When the user selects tasks’ group categories from the list, the panel displays the tasks’ groups belonging to those categories in the bar chart.
