A graph of all the callers of the function is displayed in the Graph area . Note that if the toggle-source-debugging function has not been used to set source debugging to t (its default setting), the graph view has no information to display.
The graph area of the Calls Into view is the same, other than the fact that the graph displayed is of the functions called by the function being browsed.
The generic facilities available to all graph views throughout the environment are available here; see Manipulating Graphs for details.
