Fig. 1 | Protein abundance after treatment. a, Representative western blot with molecular weight markers. b, Quantification of protein abundance. Data are mean ± s.e.m.; n = 3 biologically independent experiments. P values were calculated by two-way ANOVA with Šídák’s multiple-comparisons test.

Figure 1. Localization of a fluorescent marker. (A–C) Representative immunofluorescence images. (D) Quantification of fluorescence intensity. Scale bars, 20 µm. See also Figure S2.
Fig 1. Dose–response relationship. (A) Response across treatment concentrations; IC50 and 95% CI are indicated. Illustration created for this example.
Fig. 1. Survival by treatment group. (A) Kaplan–Meier survival curves with numbers at risk; HR and 95% CI are shown. P values were calculated by log-rank test.
Figure 1. Model accuracy across datasets. (A) Accuracy across datasets. Data are mean ± SD; n = 5 random seeds.

The text that accompanies a figure: a title stating what the figure shows, a description of each panel, and the information needed to read it on its own — what error bars show, what n counts, which test produced each P value, and scale bars.
Mostly. Biomedical journals such as Nature and Cell say “legend”; APA Style and many other fields say “caption”. This tool writes both.
Start with a one-sentence title for the whole figure, write one or two sentences per panel describing what is shown, then define statistics, sample sizes, scale bars and abbreviations. The checklist flags what is missing. Cumming et al. (2007).
Nature, Cell Press, PLOS ONE, Science, APA Style and a generic format. Each changes the figure label, panel labels and statistics wording; always check your journal’s current author guidelines.
The figure number in bold above the figure, the title in italic title case on the next line, and a Note below the figure for explanations, abbreviations and probability values.
Copy legend keeps bold and italic when pasted into Word or Google Docs. The Copy menu also gives plain text, LaTeX and Markdown.
It reads visible figure details and uses only facts in your notes. Missing information becomes placeholders, and new numbers are highlighted for checking. Each write or polish uses 10 credits and requires a free account. Formatting and the checklist are free.
When you write, your figure and notes are sent to our AI provider. If safety checks are enabled, your image is uploaded to an image provider's temporary file address and sent to the moderation provider for image checks, and your notes are sent to the moderation provider for text checks. Figran does not store them on its servers; we record character counts, image size and credit usage. Drafts stay in this browser tab.
It can read panels, figure types, axes and scale bars. Supply sample sizes, tests, error bars and other facts the image cannot show; otherwise they remain placeholders.
Add your details, review the legend, and copy it for your manuscript.
