Using the Range Navigator

At the top of each tab is a graphical range navigator that allows you to select the range of events for which you want to display recording information. The range navigator is a timeline that shows all events in a recording that pertain to the data displayed on the selected tab (for example, the range navigator on Hot Methods tab of the Code tab group shows the events that apply to method sampling).

The events are indicated by vertical lines that vary in height, based on the number of events. A longer vertical line indicates that more events have occurred at that point in the recording. If no events occurred at a certain time, no lines are displayed at that point in time.

At each end of the range navigator are the range selection bars. You can click these bars with the mouse pointer and drag them along the range navigator to change the range of events displayed on the tab. The range selection bars are activated when you hover the mouse pointer over the range navigator.

In addition to the range selection bars, you can adjust the range of data by selecting one of the buttons below the navigator timeline. The following table describes each of those buttons:
