Legend structure
What a Publication-Style Figure Legend Should Include
A good legend does more than name the objects in an image. It explains the scientific reading order, defines visual conventions, and gives readers enough context to interpret the figure without searching through the manuscript. Ask for the visual structure you need, then verify the finished wording against the actual study before publication.
State the scientific message
Open with one sentence that identifies what the figure shows and why the relationship matters. Name the system, intervention, comparison, or workflow without repeating the manuscript title. A useful legend helps a reader understand the figure independently, but it should not introduce a new conclusion that the data do not support. Keep the opening descriptive and reserve interpretation for the final sentence only when the evidence justifies it.
Define panels, symbols, and groups
Explain panels in reading order and define every abbreviation, color, line style, arrow type, and symbol that is not universally understood. If panels A–D show different methods or conditions, say so directly instead of making readers infer the mapping. Keep the wording parallel across panels, and use the same terminology as the labels inside the image. This is especially important when a figure combines a mechanism, experimental workflow, and quantitative result.
Report only necessary conditions
Include the experimental conditions required to interpret the figure: sample identity, treatment, time point, temperature, scale, units, normalization, or statistical notation when relevant. Do not copy the entire methods section into the legend. For a conceptual diagram, clearly describe it as a schematic rather than implying that arrows, dimensions, or intensities are measured values. Exact conditions should come from the study record, not from the image generator.
Separate description from interpretation
A figure legend should distinguish what is visually encoded from what the authors conclude. Describe solid and dashed arrows, groups, controls, and outcomes first. Then add a concise interpretation only if the journal format calls for it. Avoid causal verbs when the experiment shows association, and avoid claiming significance unless the statistical comparison is present and defined. This separation makes the figure easier to review and reduces the risk of an illustration overstating the research.

Annotation guidance
Reference Labels for Mechanisms, Workflows, and Methods
Useful labels connect a visual element to a precise scientific meaning. They may identify a structure, define an arrow, record a parameter, or point readers to a source note. Include these requirements in the description before generating, then check every callout at full size so a polished layout does not conceal an incorrect connection.
Mechanisms and pathways
For a mechanism or pathway, reference labels should identify the exact molecule, complex, compartment, material, or state being discussed. Define whether an arrow represents activation, inhibition, conversion, binding, transport, or a proposed relationship. Use consistent names across the figure, legend, and manuscript, and avoid adding a component simply because it is common in a textbook pathway. When evidence is indirect, words such as “proposed” or “associated with” are more accurate than a definitive causal label.
Experimental workflows and methods
Workflow labels should make the sequence auditable. Number the steps, identify the input and output of each stage, and add parameters such as duration, temperature, flow rate, concentration, or instrument mode only when they are known and relevant. Use branches for genuine decisions or parallel analyses, not as decoration. For apparatus figures, connect callouts to the correct port, chamber, sensor, or measurement zone and keep directional arrows consistent with the physical process.
Citation and source notes
A reference label inside an image is not a substitute for a bibliographic citation. If a mechanism, structure, or workflow is adapted from previous work, place the citation in the manuscript or figure legend according to the target journal’s style. Identify whether the figure is original, adapted, or reproduced, and obtain permission when required. Keep source notes separate from panel labels so readers can distinguish scientific annotation from publication attribution.
