Rules for Viewgraphs
Most important: keep them:
- necessary to the story line.
Controversy: Number of viewgraphs vs. amount of material per viewgraph.
On the one hand:
- Transparencies should illustrate a single point and, like the
presentation itself, have only one focus
- The less busy a viewgraph appears, the more justice it does to
the information it attempts to communicate
- Complex data/figures cannot be fully appreciated unless the
speaker separates them into a series of simplified constituents.
On the other hand:
- Flipping through many viewgraphs fragments the talk.
- Clearly organizing each part of the story on one viewgraph allows
gives audience sufficient info in one place so they can absorb it.
- Putting related figures/data on one viewgraphs allows
relationships to be displayed and explained.
Agreement exists on:
- Try to avoid showing tables. Keep fewest significant digits.
- Equations intimidate most audience who then "tune out" of the talk.
Use with care, introducing the physics of the symbols first.
Never change a symbol within a viewgraph or from one to the next.
- Lettering on viewgraphs can never be too large, at least 17 point.
- Uniformity of style throughout the presentation accentuates and
underscores the flow and coherence of the talk.
- Clearly label axes
- Delete all information (curves/words) irrelevant to talk.
- Explain main points of figure directly on the viewgraph.
