The Timeline settings enable you to specify the information displayed in the Timeline View.
Select the kinds of data to display. The selection applies to all experiments and all display types. If a data type is not included in an experiment, the data type is not displayed in the settings as a selectable data type.
Select to display a CPU Utilization Samples bar for each process. The Samples bar shows a graph summarizing the microstate information for each periodic sample.
Select to display a timeline bar of clock profiling data captured for each LWP, thread, CPU, or experiment. The bar for each item shows a colored call stack of the function that was executing at each sampled event.
Select to display a timeline bar of hardware counter profiling data.
Select to display a timeline bar of I/O tracing data.
Select to display a timeline bar of heap tracing data.
Select to display a timeline bar of synchronization tracing call stacks.
Select to add a graph to each timeline bar to show the microstate for each event. Event Density - select to add a graph to each timeline bar to show when an event occurs.
Specify how to organize the timeline bars for each process - by LWP, thread, CPU, or for the overall process. You can also set the grouping using the Group Data list in the Timeline toolbar.
Specify whether the call stacks displayed in the timeline event markers are aligned on the leaf function or the root function. Select leaf if you want the last function called to be shown at the bottom of the stack. This setting does not affect the data presented in the Selection Details panel, which always displays the leaf function at the top.
Specify how many pixels should be used when displaying each function in a call stack. A value of three is the default. This setting, along with the timeline vertical zoom which controls the available space per row, determines whether or not deep call stacks will be truncated or fully displayed.
