  Choose the Lexical Tree menu item from the View pull- down menu to
  graphically display the Graph query results in lexical order.  A
  lexical tree shows all nodes (routines) and arcs (call references)
  for the current query.  For example, routine A may call routine B
  twice.  Two separate nodes will appear for routine B, as well as two
  arcs from routine A.
