Graphs should have a figure number referenced in the text but no title, axes scaled appropriately without extra whitespace or trailing zeros, titles and units consistent with the text, appropriate gridlines or tick marks, distinguish between discrete and continuous data, clarify trendlines showing equations and variance, differentiate multiple series with a key, and use clear line and point styles to distinguish between series.

- 1. © The University of Sheffield TECHNICAL REPORT WRITING FOR ENGINEERS CREATING GRAPHS – THE KEY POINTS Make sure that… • there isn’t a title on the graph itself, but in the caption • the graph has a figure number that is referred to from the text • axes are scaled appropriately to not misrepresent the data or leave too much whitespace on the graph • numbers used on the axes have a minimum number of significant figures and no trailing zeros • axes have title and, if appropriate, units that are consistent with those used in the text • gridlines are only used if appropriate and if they are not, tick marks appear on the axes • that discrete data is represented with points and continuous data is represented with lines • if a trendline is used, it is clear that it is a trendline (not original data) and include the equation and variance • multiple series on the same graph can clearly be differentiated with a suitable key • the choice of lines style (thickness, colour dashed) and point style (colour, shape, size) allow readers to clearly tell the difference between series.
