Concept reference
Figure legend: a worked reference
The reference shows a four-part legend scaffold: Question, Panels and labels, Methods and scale, Interpretation and limits. It is a writing aid for an existing figure, not a substitute for the underlying methods or data.
Figure legend element key
Use the reference and definitions together. On a small screen, scroll the table horizontally.
| Element | Meaning | Review check |
|---|---|---|
| Question | Why the figure exists | State the scientific or explanatory question in one sentence. |
| Panel map | What each panel, mark or color means | Define labels, symbols, groups and abbreviations. |
| Methods and scale | How the image was made and measured | Include relevant method, scale bar, units or sample details from the source. |
| Result statement | What the figure supports | Use only claims supported by the figure and analysis. |
| Limit | What the figure cannot show | Avoid extending an image beyond its design or evidence. |
Plan your figure legend
A legend explains an existing figure; it should not manufacture methods, sample sizes or findings that are absent from the source.
Describe before interpreting
Start with what is visibly shown, then explain the interpretation supported by the source.
Keep methods traceable
A legend can summarize methods, but it cannot replace the full protocol or add missing details.
State the scale
Readers need units, scale bars, magnification or image-processing notes when those affect interpretation.
Common mistakes to avoid
Invented sample details
Never fill a missing n, p-value, dose or time point with a plausible guess.
Undefined colors
A palette is not a legend. Explain what each color or symbol encodes.
Overclaiming from one panel
Match the interpretation to the analysis and scope of the complete figure.
Build a figure legend from verified details
The figure legend builder runs in your browser without an account, credits or image upload. It assembles the facts you enter; it does not use AI to infer details from a figure.
Check the draft against the actual figure and the journal instructions. Leave unknown values out until verified; never substitute a plausible number.

Before you copy the legend
Check panel letters, methods, units, scale bars, abbreviations and the exact scope of the interpretation against your existing figure. Include sample details and statistics only when verified from the study record.

What is a figure legend?
It is the explanatory text that identifies what a figure shows, how it was produced and how it should be interpreted.
Does the generator analyze an uploaded image or raw data?
No. This local builder combines the verified text you enter. It does not upload images, analyze data, infer methods or invent missing results.
Should a legend include methods?
Include the methods needed to understand the image, while keeping the full protocol in the methods section.
What if a detail is missing?
Leave a placeholder or verify the source. Do not invent a number or claim to make the prose sound complete.
