Use the calipers on the timeline to select a region of time. The Call Paths, Functions, and Code views update to show data for the time period set with the calipers.
Drag the calipers to set the required time region, or right-click on the timeline and select Set Left Caliper or Set Right Caliper.
To reset the calipers so they include all the data, click Reset Calipers
on the toolbar of the Live or Timeline view.
