Publication Chart Skill

Goal

Use this skill to turn research results into publication-grade figures and tables with an end-to-end workflow.

Primary production stack:

• pubfig for figures
• pubtab for publication tables

This skill covers the full delivery chain:

1. understand the scientific communication goal,
2. choose the right artifact type,
3. map the task to pubfig, pubtab, or both,
4. generate concrete runnable instructions,
5. export paper-ready assets,
6. run publication QA,
7. propose targeted revisions.

Use this skill when

Trigger this skill for requests like:

• “make a publication-quality figure”
• “choose the right chart for these results”
• “turn these results into a paper-ready figure”
• “make a benchmark / ablation / calibration / forest / heatmap / scatter / line / bar figure”
• “make a benchmark / appendix / ablation table from Excel”
• “convert this Excel table into publication-ready LaTeX”
• “prepare one summary figure plus one companion table for the results section”
• “review and improve this scientific figure/table”
• “I already have a weak chart / screenshot / draft plot — make it publication-ready”
• “export panels for a paper figure”

Do not use this skill for

Do not use this skill when the task is mainly:

• manuscript prose writing,
• statistical testing without artifact design,
• raw exploratory analysis with no publication deliverable,
• Figma-first layout work before the figure/table content is solid.

For simple composite assembly after the figure content is already strong, use the optional secondary workflow in references/composite-assembly.md.

Primary contract

Inputs

Expect some combination of:

• the scientific communication goal,
• available data shape,
• venue or style constraints,
• whether the artifact is a figure, table, or mixed deliverable,
• optional existing assets such as code, spreadsheets, .tex, screenshots, or draft plots,
• whether the user needs a first draft, a publication-ready artifact, or a review/revision pass.

Outputs

The minimum useful output is:

• the recommended figure/table form,
• the recommended pubfig / pubtab route,
• a minimal runnable code snippet or CLI command,
• explicit export filenames and formats,
• a publication QA summary,
• and, when needed, a revision plan.

Default workflow

0. Probe the environment and artifact state

Before generating anything, identify:

• whether pubfig or pubtab is actually available,
• whether the user already has code / spreadsheets / .tex / screenshots,
• whether the deliverable is a fresh build or a revision,
• whether the result needs exact values, fast visual perception, or both.

Prefer the smallest environment check that helps execution. When the bundled helper script is available, use it first:

• python3 scripts/ensure_publication_tooling.py --require pubfig --json
• python3 scripts/ensure_publication_tooling.py --require pubtab --json

Equivalent manual checks are still acceptable when needed:

• python -c "import pubfig; print(pubfig.__version__)"
• python -c "import pubtab; print(pubtab.__version__)"
• pubtab --help

Report the result clearly as available or missing.

If a dependency is missing and the task requires runnable execution:

• auto-install it by default,
• prefer the user’s active environment instead of guessing a random global interpreter,
• use python3 scripts/ensure_publication_tooling.py --require ... as the default bundled route when the script is present,
• let that helper choose uv vs python -m pip against the active interpreter,
• re-run the availability probe after installation,
• and only then continue with the artifact workflow.

Equivalent concrete commands include:

• python3 scripts/ensure_publication_tooling.py --require pubfig
• python3 scripts/ensure_publication_tooling.py --require pubtab
• uv pip install pubfig
• uv pip install pubtab
• python -m pip install pubfig
• python -m pip install pubtab

If auto-install fails, report the exact failure and then degrade gracefully.

Do not block on a full environment audit.

1. Classify the task

Classify the request along these axes:

• artifact type: figure / table / mixed deliverable
• maturity: exploratory draft / publication-ready generation / revision of an existing artifact
• structure: single panel / multi-panel / figure-plus-table package
• evidence mode: pattern perception / exact value lookup / both

Do not jump into plotting code before the communication target is clear.

Before plotting research results, lock the evidence contract:

• primary scientific claim,
• unit of analysis,
• primary metric and metric direction,
• whether repeated rows are independent,
• missing cells or incomplete comparison blocks,
• error-bar basis: subject, subject-task, fold, seed, run, or bootstrap sample,
• whether exact values need a companion table,
• whether the current evidence allows a winner/significance claim.

If these are unclear, ask or produce an audit recommendation instead of a polished figure. Do not create a paper-ready plot while the unit of analysis, missing-cell handling, or error-bar basis is unresolved.

2. Choose the representation

Choose the representation based on the scientific claim, not novelty or visual flair.

Common families:

• comparison — grouped scatter, bar, line comparison, benchmark summary, companion table
• ablation — grouped comparison, dumbbell, paired comparison, compact table
• distribution — box, violin, raincloud, histogram, density, ECDF, QQ
• relationship — scatter, bubble, contour2d, hexbin
• trend — line, area
• evaluation / diagnostic — calibration, ROC, PR, Bland–Altman, forest plot, volcano
• composition / hierarchy — UpSet, stacked ratio, donut, radial hierarchy, circular grouped or stacked bars
• table — benchmark table, ablation table, dataset summary, appendix table, error breakdown

Avoid weak defaults:

• avoid pie/donut when exact comparison matters and a bar/table is clearer,
• avoid radar unless the comparison is genuinely profile-like and low-cardinality,
• avoid 3D, decorative gradients, and dense legends used only for style,
• avoid forcing every result into a figure when a publication table communicates the evidence better.

If the request is ambiguous, explicitly state what scientific claim the artifact is supposed to support.

3. Map to the toolchain

Default mapping:

• Figures → pubfig
• Tables → pubtab
• Mixed deliverables → use both, with each artifact carrying a distinct role

Tool roles:

• pubfig is the default figure engine for scientific plots and paper-ready export.
• pubtab is the default table engine for Excel ↔ LaTeX workflows, preview, and publication-ready table export.
• Figma/composite assembly is an optional secondary branch for multi-panel finishing.

Route selection rules:

• prefer Python for pubfig figure generation,
• prefer CLI for pubtab when the task is file-driven,
• prefer Python for pubtab when the task is already inside a notebook or scripted pipeline,
• keep the figure and table responsibilities separate in mixed requests.

4. Generate concrete artifact instructions

Prefer the smallest production-ready artifact first:

• minimal runnable Python for pubfig, or
• minimal CLI/Python for pubtab

Then add publication parameters only when justified:

• labels, caption, width, export format, backend, preview, panel packaging, or composite layout.

Keep filenames and suffixes explicit.

Good defaults:

• figures: one pubfig call + one save_figure(...)
• multiple figure outputs: batch_export(...)
• tables: one pubtab xlsx2tex ... or pubtab.preview ...
• mixed requests: one figure route + one table route, clearly separated

5. Define the delivery contract

For every response, make these explicit when possible:

• the claim the artifact supports,
• which part is handled by pubfig and which by pubtab,
• the output filenames,
• the output formats,
• whether the artifact is draft / final / revision,
• what still needs user-provided data or manuscript context.

6. Run publication QA

After generation, check:

• title and legend density,
• axis labels and units,
• category ordering and baseline clarity,
• color accessibility and grayscale robustness,
• font / line-weight consistency,
• caption readiness,
• figure/table readability after downscaling,
• panel consistency for multi-panel figures,
• venue-fit issues such as width, crowding, or over-annotation.

The QA output must be concrete. Do not say “looks better” without naming why.

7. Revise

If the result is weak, revise with specific changes such as:

• switch chart family,
• remove chartjunk,
• reorder categories,
• move exact values into a table,
• split a crowded panel,
• add or simplify the caption,
• change export width,
• or convert the deliverable from figure-first to table-first.

Missing dependency behavior

If pubfig or pubtab is not available:

• do not fail immediately,
• first attempt automatic installation into the active environment,
• prefer python3 scripts/ensure_publication_tooling.py --require ... when the bundled script exists,
• explicitly state which dependency is missing,
• state which install command or helper route is being used,
• re-check availability after installation,
• if installation succeeds, continue with the runnable workflow,
• if installation fails, degrade to a design/specification workflow,
• provide pseudocode or draft commands,
• preserve the recommended figure/table structure,
• still provide QA and revision guidance.

Composite assembly rule

Treat composite or Figma assembly as secondary:

• use it when the user explicitly wants a multi-panel paper figure,
• or when panel-level export and layout polishing are genuinely needed.

Do not escalate simple figure tasks into composite/Figma workflows by default.

Output style rules

• Prefer direct, implementation-usable outputs.
• Explain the why of chart/table choice briefly, then give the runnable route.
• When execution matters, include a short environment status block such as pubfig: available/missing, pubtab: available/missing.
• If a dependency is missing, state the exact helper command or install command, perform the installation, and report the post-install status.
• When a table is stronger than a figure, say so explicitly.
• When a figure is stronger than a table, say so explicitly.
• When both are needed, assign them different communication roles.
• Keep revision guidance actionable and falsifiable.

Recommended response shape

A strong response using this skill usually has 6 parts:

1. Artifact decision — figure / table / paired deliverable, and why
2. Tool route — pubfig, pubtab, or both
3. Minimal implementation — runnable code or CLI
4. Export plan — filenames, formats, width/backend/preview choices
5. Publication QA — what to verify before paper submission
6. Revision plan — what to change if the current artifact is weak
