Choosing the Diagram View
The Program Control Flow pane offers two views of program control flows, a subgraph view and a subtree view. The figures below show the same paragraphs in both views.
Subgraph View
The subgraph view offers a cyclic representation of the information in the diagram. Items are drawn once. Relationship lines
cross. Subgraph views are often easier to understand than subtree views. Click the
button on the toolbar at the bottom of the pane to select the subgraph view.
Subtree View
The subtree view offers a linear representation of the information in the diagram. Items are drawn as many times as necessary.
Relationship lines do not cross. Use this view if too many intersecting lines make a subgraph view hard to read. Click the
button on the toolbar at the bottom of the pane to select the subgraph view.
