The Tree view displays the detailed profile data as shown in Figure 2. For example, details of the functions called by a particular function, or the details of the instructions executed in a function. This means that a function may appear more than once in the profile if it called from different functions.
The Tree view is useful for detecting design problems in code. It lets you see the functions that are called from other functions and also how often those functions are called. Armed with knowledge of your code's underlying design, you may discover flow-control problems.
You can use the Expand All or Collapse All options in the View context menu to open or close the entire hierarchy at once. These options are available only when you select the Tree View or Class View options.
