PATTERNS OFTEN USED IN EXPLAINERS

Here are some common frame arrangements.  Letters (A, B, ...) represent any chunks of content information in any form or quantity.


1. Frames may be entered via the top edge or via an arrow.  Frames may be exited via the bottom edge or via an arrow.
2. When A is true, or is applicable, move to B. Linking is accomplished by making all or part of the bottom edge of one frame overlap the top or part of the top edge of a frame or frames.

3. There are three valid paths (scenarios): AC; AD; BD.  Do not cross through vertical lines.

4. There are two paths: A;  BC.   A is barriered.  A and B are not accessible to each other.

5. Twelve paths are represented.

6. Content conditions are unlimited.

7. A miniature empty Explainer with a horizontal barrier, and an arrow.  There are 39 paths.  Arrows sometimes can be avoided by using duplicate frames, a common practice.

8. Frames with identical content (D, here) can appear multiple times.
