Figure Legend: Explain What the Reader Is Seeing and How
Use a figure legend generator to draft a clear scientific figure legend from an existing image. Cover the question, methods, labels, scale and limits without inventing results.
Use the figure legend generator to organize verified descriptions of an existing figure into a copyable text draft. Enter the title, panels, methods, symbols and limitations yourself; the builder combines those details without inferring missing results.

Original AI-generated figure legend scaffold commissioned by AcaDraw. Writing aid for an existing figure; replace placeholders with verified details.
Give the reader a map
Start with the question and identify each panel in the order a reader will encounter it. A compact panel map prevents the legend from becoming a second methods section.
Define colors, symbols, abbreviations and scale bars before discussing what the image may support.
Draft from facts you can verify
The local builder has fields for title, panel descriptions, methods, symbols, sample details and interpretation. It combines only the text supplied by the user. It does not inspect pixels, identify a statistical test or infer sample size from the apparent number of marks. Empty optional fields are omitted from the draft.
For a schematic, sample details may be inapplicable. For a microscopy image, a scale bar and preparation details may be essential. Match the fields to the source figure and the journal’s requirements. Before copying the draft, confirm that abbreviations, panel letters and units agree with the image.
Separate observation and interpretation
“The blue points are participants in group A” is a description if the source defines that encoding. “Group A responds better” is an interpretation that must be supported by the analysis. Keep those levels distinct.
A generator can organize the sentences, but a researcher must verify them against the original figure and study record.
Protect reproducibility
A useful legend records details that affect interpretation: units, scale, image processing, sample scope and relevant exclusions. If a detail is unavailable, say so or link to the method rather than guessing.
Figure legend element key
| 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. |
A review before sharing
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.
Checks before sharing
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.
Common questions
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.
