6.11 Show Credibility
You might want to share a graph from a famous journal authored by a Nobel prize
winner for credibility purposes. Unfortunately, graphs from original sources are
generally NOT appropriate for on-screen presentations:
• Fonts might be too small (typical for a scientific paper in print)
• Image quality might be poor (poor scanning from an old article)
• Way too much info shown – you may only care about a few things on it
Here is some advice:
• Show the original graph, mentioning its source (reference, author) to emphasize
its trustworthiness
• After a few seconds, grey it out (replace it by an identical greyed out version at
the exact same spot – see Sect. 4.10)
• You then superimpose your own graph on top of it, without removing the original
greyed out original:
• First introduce axes (on top of the original ones)
• Then highlight only the information you want to convey, superimposed on the
original graph
• Then, just remove the original greyed out graph. Only your own variant remains,
which is now perfectly suited for your purpose, while still clearly inspired from
the famous original
