How to Cite A Chart in Chicago Edition
Chicago Notes & Bibliography asks for fuller repository detail when you cite a chart—especially medium, dimensions when known, and the holding institution with city—then a URL if you consulted a digital surrogate. A chart citation should recover the dataset or report behind the numbers, not just the slide that reused the visual.

Special rules for charts
- Credit the analyst or organization that published the chart and name the underlying data source when listed.
- If you redraw the chart, cite the data source and note that the figure is adapted.
- Include the chart title exactly as published; add [Chart] or [Graph] when the style needs a format tag.
Source of truth: The dataset or report that produced the chart—not only the slide deck that reused it.
Common mistakes
- Citing only “Statista” without the specific chart title and year.
- Pointing readers to a dashboard login wall with no public URL.
- Treating a screenshot of a chart as a photograph without noting it is a chart.
FAQ
How do you cite a chart in Chicago?
Build one Chicago reference from creator → date → title → “Chart” → host. Then paste the finished string into your reference list; do not leave the format field blank or point to a search-results URL.
What is the in-text citation for a chart in Chicago?
Match the creator spelling used in the reference entry and apply Footnote number after the sentence; shortened subsequent notes.. If the chart is labeled as a numbered figure in the paper, add that figure number only where your instructor’s Chicago handout allows.
Do I need a figure caption when I include a chart in my paper (Chicago)?
Only if you reprint the visual. A mention in prose needs in-text + reference list; a reproduced chart also needs a numbered caption so readers can connect the picture on the page to the bibliography entry.
Where should I look for source details for a chart?
Start on the object or article page that displays the chart, then read the credit line, about panel, or download metadata. Skip aggregator cards and thumbnail feeds—they rarely carry a citable creator or permanent link.
What is a common mistake when citing charts in Chicago?
Students often citing only “Statista” without the specific chart title and year. Another frequent miss: treating a cropped social share as the publisher of record.
How is citing a chart different from citing a generic online photo in Chicago?
A generic photo citation can stop at photographer + site + URL. For charts, you also have to capture credit the analyst or organization that published the chart and name the underlying data source when listed. That extra field is what keeps the entry recoverable.
