Special rules for graphs

  • Preserve axis labels and units in your figure note when you reproduce the graph.
  • If the graph comes from a journal article, cite the article as the container when required.
  • Distinguish line graphs, bar graphs, and scatterplots in the format description when helpful.

Source of truth: The paper, report, or data portal that first published the graph axes and series.

Common mistakes

  • Citing a blog that embeds the graph instead of the original dataset or paper.
  • Leaving out the year the data series covers versus the year of publication.
  • Forgetting an “adapted from” note after you restyle colors or crop axes.
