Paper Figure: Publication-Quality Plots from Experiment Data

Generate all figures and tables for a paper based on: $ARGUMENTS

Scope: What This Skill Can and Cannot Do

Category	Can auto-generate?	Examples
Data-driven plots	✅ Yes	Line plots (training curves), bar charts (method comparison), scatter plots, heatmaps, box/violin plots
Comparison tables	✅ Yes	LaTeX tables comparing prior bounds, method features, ablation results
Multi-panel figures	✅ Yes	Subfigure grids combining multiple plots (e.g., 3×3 dataset × method)
Architecture/pipeline diagrams	❌ No — use paper-figure-archi for a reference image, then redraw manually	Model architecture, data flow diagrams, system overviews. Use the generated reference as guidance for draw.io, Figma, PowerPoint, TikZ, or another editable tool
Generated image grids	❌ No — manual	Grids of generated samples (e.g., GAN/diffusion outputs). These come from running your model, not from this skill
Photographs / screenshots	❌ No — manual	Real-world images, UI screenshots, qualitative examples

In practice: For a typical ML paper, this skill handles ~60% of figures (all data plots + tables). The remaining ~40% (hero figure, architecture diagram, qualitative results) need manual or separate workflows. Use paper-figure-archi to create a raster reference for architecture diagrams, then redraw the final figure in an editable format and place it in figures/ before running /paper-write. This skill will detect existing figures and preserve them.

Constants

• STYLE = publication — Visual style preset. Options: publication (default, clean for print), poster (larger fonts), slide (bold colors)
• DPI = 300 — Output resolution
• FORMAT = pdf — Output format. Options: pdf (vector, best for LaTeX), png (raster fallback)
• COLOR_PALETTE = tab10 — Default matplotlib color cycle. Options: tab10, Set2, colorblind (deuteranopia-safe)
• FONT_SIZE = 10 — Base font size (matches typical conference body text)
• FIG_DIR = figures/ — Output directory for generated figures
• REVIEW_ROLE = paper architect/reviewer — Use the AGENTS.md paper review role for figure quality diagnosis. Do not hard-code a model.

Inputs

1. PAPER_PLAN.md — figure plan table (from /paper-plan)
2. Experiment data — JSON files, CSV files, or screen logs in figures/ or project root
3. Existing figures — any manually created figures to preserve

If no PAPER_PLAN.md exists, scan for data files and ask the user which figures to generate.

Workflow

Step 1: Read Figure Plan

Parse the Figure Plan table from PAPER_PLAN.md:

| ID | Type | Description | Data Source | Priority |
|----|------|-------------|-------------|----------|
| Fig 1 | Architecture | ... | manual | HIGH |
| Fig 2 | Line plot | ... | figures/exp.json | HIGH |

Identify:

• Which figures can be auto-generated from data
• Which need manual creation (architecture diagrams, etc.)
• Which are comparison tables (generate as LaTeX)

Step 2: Set Up Plotting Environment

Create a shared style configuration script:

# paper_plot_style.py — shared across all figure scripts
import matplotlib.pyplot as plt
import matplotlib
matplotlib.rcParams.update({
    'font.size': FONT_SIZE,
    'font.family': 'serif',
    'font.serif': ['Times New Roman', 'Times', 'DejaVu Serif'],
    'axes.labelsize': FONT_SIZE,
    'axes.titlesize': FONT_SIZE + 1,
    'xtick.labelsize': FONT_SIZE - 1,
    'ytick.labelsize': FONT_SIZE - 1,
    'legend.fontsize': FONT_SIZE - 1,
    'figure.dpi': DPI,
    'savefig.dpi': DPI,
    'savefig.bbox': 'tight',
    'savefig.pad_inches': 0.05,
    'axes.grid': False,
    'axes.spines.top': False,
    'axes.spines.right': False,
    'text.usetex': False,  # set True if LaTeX is available
    'mathtext.fontset': 'stix',
})

# Color palette
COLORS = plt.cm.tab10.colors  # or Set2, or colorblind-safe

def save_fig(fig, name, fmt=FORMAT):
    """Save figure to FIG_DIR with consistent naming."""
    fig.savefig(f'{FIG_DIR}/{name}.{fmt}')
    print(f'Saved: {FIG_DIR}/{name}.{fmt}')

Step 3: Auto-Select Figure Type

Use this decision tree for data-driven figures (inspired by Imbad0202/academic-research-skills):

Data Pattern	Recommended Type	Size
X=time/steps, Y=metric	Line plot	0.48\textwidth
Methods × 1 metric	Bar chart	0.48\textwidth
Methods × multiple metrics	Grouped bar / radar	0.95\textwidth
Two continuous variables	Scatter plot	0.48\textwidth
Matrix / grid values	Heatmap	0.48\textwidth
Distribution comparison	Box/violin plot	0.48\textwidth
Multi-dataset results	Multi-panel (subfigure)	0.95\textwidth
Prior work comparison	LaTeX table	—

Step 4: Generate Each Figure

For each figure in the plan, create a standalone Python script:

Line plots (training curves, scaling):

# gen_fig2_training_curves.py
from paper_plot_style import *
import json

with open('figures/exp_results.json') as f:
    data = json.load(f)

fig, ax = plt.subplots(1, 1, figsize=(5, 3.5))
ax.plot(data['steps'], data['fac_loss'], label='Factorized', color=COLORS[0])
ax.plot(data['steps'], data['crf_loss'], label='CRF-LR', color=COLORS[1])
ax.set_xlabel('Training Steps')
ax.set_ylabel('Cross-Entropy Loss')
ax.legend(frameon=False)
save_fig(fig, 'fig2_training_curves')

Bar charts (comparison, ablation):

fig, ax = plt.subplots(1, 1, figsize=(5, 3))
methods = ['Baseline', 'Method A', 'Method B', 'Ours']
values = [82.3, 85.1, 86.7, 89.2]
bars = ax.bar(methods, values, color=[COLORS[i] for i in range(len(methods))])
ax.set_ylabel('Accuracy (%)')
# Add value labels on bars
for bar, val in zip(bars, values):
    ax.text(bar.get_x() + bar.get_width()/2, bar.get_height() + 0.3,
            f'{val:.1f}', ha='center', va='bottom', fontsize=FONT_SIZE-1)
save_fig(fig, 'fig3_comparison')

Comparison tables (LaTeX, for theory papers):

\begin{table}[t]
\centering
\caption{Comparison of estimation error bounds. $n$: sample size, $D$: ambient dim, $d$: latent dim, $K$: subspaces, $n_k$: modes.}
\label{tab:bounds}
\begin{tabular}{lccc}
\toprule
Method & Rate & Depends on $D$? & Multi-modal? \\
\midrule
\citet{MinimaxOkoAS23} & $n^{-s'/D}$ & Yes (curse) & No \\
\citet{ScoreMatchingdistributionrecovery} & $n^{-2/d}$ & No & No \\
\textbf{Ours} & $\sqrt{\sum n_k d_k / n}$ & No & Yes \\
\bottomrule
\end{tabular}
\end{table}

Architecture/pipeline diagrams (MANUAL — outside this skill's scope):

• These require manual creation using draw.io, Figma, Keynote, or TikZ
• This skill can generate a rough TikZ skeleton as a starting point, but do not expect publication-quality results
• If the figure already exists in figures/, preserve it and generate only the LaTeX \includegraphics snippet
• Flag as [MANUAL] in the figure plan and latex_includes.tex

Step 5: Run All Scripts

# Run all figure generation scripts
for script in gen_fig*.py; do
    python "$script"
done

Verify all output files exist and are non-empty.

Step 6: Generate LaTeX Include Snippets

For each figure, output the LaTeX code to include it:

% === Fig 2: Training Curves ===
\begin{figure}[t]
    \centering
    \includegraphics[width=0.48\textwidth]{figures/fig2_training_curves.pdf}
    \caption{Training curves comparing factorized and CRF-LR denoising.}
    \label{fig:training_curves}
\end{figure}

Save all snippets to figures/latex_includes.tex for easy copy-paste into the paper.

Step 7: Figure Quality Review

Delegate figure descriptions and captions to the paper architect/reviewer role:

Paper architect/reviewer task:
  Review these figure/table plans for a [VENUE] submission.

  For each figure:
  1. Is the caption informative and self-contained?
  2. Does the figure type match the data being shown?
  3. Is the comparison fair and clear?
  4. Any missing baselines or ablations?
  5. Would a different visualization be more effective?

  [list all figures with captions and descriptions]

Step 8: Quality Checklist

Before finishing, verify each figure (from pedrohcgs/claude-code-my-workflow):

• Font size readable at printed paper size (not too small)
• Colors distinguishable in grayscale (print-friendly)
• No title inside figures — titles go only in LaTeX \caption{} (from pedrohcgs)
• Legend does not overlap data
• Axis labels have units where applicable
• Axis labels are publication-quality (not variable names like emp_rate)
• Figure width fits single column (0.48\textwidth) or full width (0.95\textwidth)
• PDF output is vector (not rasterized text)
• No matplotlib default title (remove plt.title for publications)
• Serif font matches paper body text (Times / Computer Modern)
• Colorblind-accessible (if using colorblind palette)

Key Rules

• Every figure must be reproducible — save the generation script alongside the output
• Do NOT hardcode data — always read from JSON/CSV files
• Use vector format (PDF) for all plots — PNG only as fallback
• No decorative elements — no background colors, no 3D effects, no chart junk
• Consistent style across all figures — same fonts, colors, line widths
• Colorblind-safe — verify with https://davidmathlogic.com/colorblind/ if needed
• One script per figure — easy to re-run individual figures when data changes
• No titles inside figures — captions are in LaTeX only
• Comparison tables count as figures — generate them as standalone .tex files
