37.12 Constructing figures and graphs
Good figures can be hard to produce, but their purpose should always be kept in mind: To display the data in the simplest, clearest possible way. In general, figures:
- Should be discussed (not just simply presented) in the text.
- Should be clear and uncluttered.
- Should typically have captions below.
- Should includes units of measurement (such as kg) where appropriate.
- Should be able to be understood without reference to the paper, as far as possible.
- Should have any colours or different line types explained.
- Should use easy-to-read fonts and colours: Make sure the writing is sufficiently large when the figure is placed in the article.
- Should not include chart junk such as artificial third dimensions (Su 2008).
