figrecipe 0.26.4

Reproducible matplotlib wrapper with mm-precision layouts

FigRecipe (scitex-plt)

Reproducible scientific figures as first-class objects

Full Documentation · pip install figrecipe

---

Installation

Requires Python >= 3.9.

pip install figrecipe

For the GUI editor:

pip install figrecipe[editor]

SciTeX users: pip install scitex[plt] already includes FigRecipe.

Quickstart

import figrecipe as fr
import numpy as np

x = np.linspace(0, 2 * np.pi, 100)

fig, ax = fr.subplots()
ax.plot(x, np.sin(x), id="sine")
fr.save(fig, "figure.png")
# Produces: figure.png, figure.yaml, figure_data/sine.csv

Reload and edit from the saved recipe:

fig, ax = fr.reproduce("figure.yaml")
fr.gui(fig)  # Launch visual editor at http://127.0.0.1:5050

FigRecipe — Reproducible, editable, publication-ready scientific figures. Part of SciTeX.

Four Freedoms for Research

0. The freedom to run your research anywhere — your machine, your terms.
1. The freedom to study how every step works — from raw data to final manuscript.
2. The freedom to redistribute your workflows, not just your papers.
3. The freedom to modify any module and share improvements with the community.

AGPL-3.0 — because research infrastructure deserves the same freedoms as the software it runs on.

SciTeX users: pip install scitex[plt] includes FigRecipe. scitex.plt delegates to figrecipe — they share the same API.

Overview

FigRecipe treats recipe, data, and style as first-class attributes of every figure. This enables data governance and style editing without losing scientific rigor.

_{Created with Diagrams}

Styling

FigRecipe provides millimeter-precise control over every visual element. The SCITEX style preset is applied by default, producing publication-ready figures with standard matplotlib plotting.

Millimeter-based Layout

fig, ax = fr.subplots(
    axes_width_mm=60,
    axes_height_mm=40,
    margin_left_mm=15,
)

Style Presets

fr.load_style("SCITEX")       # Publication defaults
fr.load_style("SCITEX_DARK")  # Dark theme
fr.load_style("MATPLOTLIB")   # Pure Matplotlib

GUI Editor

For precise adjustments, GUI editor is available.

Migration from Matplotlib

Matplotlib-compatibility

FigRecipe is a drop-in replacement for matplotlib — just change your import:

# Before
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
ax.plot(x, y)
plt.savefig("fig.png")

# After
import figrecipe as fr
fig, ax = fr.subplots()
ax.plot(x, y, id="my_trace")
fr.save(fig, "fig.png")  # → fig.png + fig.yaml + fig_data/

Systematic Migration

scitex-linter detects and auto-fixes matplotlib patterns into mm-based FigRecipe equivalents (check, format, python). It also works as a pre-commit hook, ensuring AI agents follow FigRecipe conventions.

Diagrams

Create publication-quality box-and-arrow diagrams with mm-based coordinates. See Overview for an example output.

Usage

from figrecipe._diagram import Diagram

d = Diagram(title="EEG Pipeline", gap_mm=10)

# Boxes
d.add_box(
    "raw", "Raw EEG", subtitle="64 ch", emphasis="muted", shape="cylinder"
)
d.add_box("filter", "Bandpass", subtitle="0.5-45 Hz", emphasis="primary")
d.add_box("ica", "ICA", subtitle="Artifact removal", emphasis="primary")

# Arrows
d.add_arrow("raw", "filter")
d.add_arrow("filter", "ica")

d.save(
    "pipeline.png"
)  # → pipeline.png + pipeline.yaml + pipeline_hitmap.png + pipeline_debug.png

Containers & Flex Layout

Use gap_mm on the Diagram for automatic flex layout (no manual x/y needed):

d = Diagram(title="System Overview", gap_mm=10)

d.add_box("a", "Module A")
d.add_box("b", "Module B")
d.add_container("grp", title="Core", children=["a", "b"], direction="row")
d.add_box("out", "Output", shape="document")
d.add_arrow("grp", "out")
d.save("overview.png")

Auto-Fix & Save Options

auto_fix=True automatically resolves layout violations (overlaps, container enclosure, canvas bounds, arrow collisions):

fig, ax = d.render(auto_fix=True)

# d.save() renders, auto-crops, and optionally watermarks:
d.save("out.png", watermark=True)  # "Plotted by FigRecipe" stamp

Output files from d.save():

File	Content
out.png	Auto-cropped diagram
out.yaml	Recipe for reproduction
out_hitmap.png	Click-target regions for GUI editing
out_debug.png	Debug overlay showing positions and anchors

Shapes & Anchors

Shapes: rounded (default), box, stadium, cylinder, document, file, codeblock. Use node_class for semantic defaults: "code" → codeblock, "input" → cylinder, "claim" → document.

Anchors: top, bottom, left, right, top-left, top-right, bottom-left, bottom-right, center, or auto (default). Aliases like n/s/e/w, tl/tr/bl/br are normalized automatically.

Validation Rules

All rules are enforced on render. Failed figures are saved with a _FAILED suffix for inspection.

Rule	Check	Severity
W	Width exceeds 185 mm (double-column max)	Warning
R1	Container must enclose all children	Error
R2	No two boxes may overlap	Error
R3	Container title must clear children (5 mm zone)	Warning
R4	Box text must fit within padded inner area	Warning
R5	Text-to-text margin >= 2 mm	Error
R6	Text-to-edge margin >= 2 mm	Error
R7	Arrow visible-length ratio >= 90%	Error
R8	Curved-arrow label on same side as arc	Error
R9	All elements within canvas bounds	Error

Three Interfaces

🐍 Python API

Create and save — standard matplotlib API with auto-recording:

import figrecipe as fr
import numpy as np

fig, ax = fr.subplots()
ax.plot(np.sin(np.linspace(0, 10, 100)), id="sine")
fr.save(fig, "figure.png")  # Saves + validates pixel-identical reproduction

Output:

figure.png                # Publication-ready image
figure.yaml               # Reproducible recipe (validated on save)
figure_data/
  sine.csv                # Plot data (one CSV per trace)

Save / Load Formats — from recipe or bundle:

fr.save(fig, "fig.png")     # fig.png + fig.yaml
fr.save(fig, "fig.zip")     # self-contained zip bundle
fr.load("fig.png")          # reload from any format

Format	Save	Load
PNG / PDF / SVG	✓	✓
YAML	✓	✓
Directory / ZIP	✓	✓

Reproduce and edit — from recipe or bundle:

fig, ax = fr.reproduce("figure.yaml")
fr.gui(fig)  # Launch visual editor (at http://127.0.0.1:5050 by default)

Compose — multi-panel figures:

fr.compose(
    sources=["panel_a.yaml", "panel_b.yaml"],
    output_path="composed.png",
    layout="horizontal",
)

Statistics — significance brackets:

ax.add_stat_annotation(x1=0, x2=1, p_value=0.01, style="stars")
