Better figures

A recent paper identifies 10 rules for better pictures. As I have also given several lectures on that topic, I was excited what the authors think…
1. Know your audience. This is trivial as you never know your audience.
2. Identify your message. True and not true at the same time. True as it makes your findings more evident – not true if you are allowing a reader to find his own message.
3. Adapt the figure to the support medium. Trivial. May be very time consuming.
4. Captions are not optional. Absolutely true, I also suppport good captions – mini stories for those who can’t read the whole text.
5. Do not trust the defaults. Trivial. No one does.
6. Use color efficiently.  Not really,  avoid colors for those of us who are colorblind and to avoid expensive page charges.
7. Do not mislead the reader. Why should I?
8.  Avoid Chartjunk. Absolutely. Most frequent problem.
9. Message trumps beauty. Sure, form follows function.
