Reproducible scientific figures as first-class objects
Full Documentation · pip install figrecipe
Requires Python >= 3.10.
pip install figrecipeFor the GUI editor:
pip install figrecipe[editor]SciTeX users:
pip install scitex[plt]already includes FigRecipe.
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.csvReload and edit from the saved recipe:
fig, ax = fr.reproduce("figure.yaml")
fr.gui(fig) # Launch visual editor at http://127.0.0.1:5050FigRecipe is the first app built on the SciTeX platform -- it proves the app pattern that other apps follow. It works standalone (figrecipe gui) AND embedded inside scitex-cloud.
scitex (orchestrator) -- re-exports figrecipe as scitex.plt
|-- scitex-app -- runtime SDK (FigRecipe inherits ScitexAppConfig)
|-- scitex-ui -- React/TS components (FigRecipe consumes these)
+-- figrecipe (this package) -- reference app
|-- figrecipe -- standalone Python package (pip install figrecipe)
+-- figrecipe._django -- Django integration for scitex-cloud embedding
What this package owns:
- Figure creation, reproduction, and composition engine
- YAML recipe format and data provenance
- Diagram system (box-and-arrow with mm-based coordinates)
- GUI editor (
figrecipe gui) - Django integration via
figrecipe._djangopackage
What this package does NOT own:
- App runtime SDK -- inherits from scitex-app
- UI components -- consumes from scitex-ui
- Templates and scaffolding -- managed by scitex
FigRecipe -- Reproducible, editable, publication-ready scientific figures. Part of SciTeX.
The SciTeX system follows the Four Freedoms for Research below, inspired by the Free Software Definition:
Four Freedoms for Research
- The freedom to run your research anywhere -- your machine, your terms.
- The freedom to study how every step works -- from raw data to final manuscript.
- The freedom to redistribute your workflows, not just your papers.
- The freedom to modify any module and share improvements with the community.
AGPL-3.0 -- because we believe research infrastructure deserves the same freedoms as the software it runs on.
SciTeX users:
pip install scitex[plt]includes FigRecipe.scitex.pltdelegates tofigrecipe-- they share the same API.
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
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 MatplotlibFor precise adjustments, GUI editor is available.
Details
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/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.
Create publication-quality box-and-arrow diagrams with mm-based coordinates. See Overview for an example output.
Usage
from figrecipe 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.pngContainers & 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" stampOutput 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 |
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 reproductionOutput:
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 | Y | Y |
| YAML | Y | Y |
| Directory / ZIP | Y | Y |
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"],

AI agents can create, compose, and reproduce publication-ready figures autonomously via the Model Context Protocol.
| Tool | Description |
|---|---|
plot |
Create figure from declarative YAML spec |
reproduce |
Recreate figure from recipe |
compose |
Combine panels into multi-panel layout |
crop |
Auto-crop whitespace |
info |
Inspect recipe metadata |

diagram_compile_mermaid |

audio_speak |
Text-to-speech relay to user's speakers |
Audio relay: The audio_speak tool enables AI agents to provide auditory feedback through the user's local speakers -- the agent generates text, the MCP server synthesizes speech on the host machine. This keeps the human in the loop without requiring them to watch the terminal.
Add .mcp.json to your project root. Use SCITEX_ENV_SRC to load all configuration from a .src file -- this keeps .mcp.json static across environments:
{
"mcpServers": {
"scitex": {
"command": "scitex",
"args": ["mcp", "start"],
"env": {
"SCITEX_ENV_SRC": "${SCITEX_ENV_SRC}"
}
}
}
}Then switch environments via your shell profile:
# Local machine
export SCITEX_ENV_SRC=~/.scitex/scitex/local.src
# Remote server
export SCITEX_ENV_SRC=~/.scitex/scitex/remote.srcGenerate a template .src file:
scitex env-template -o ~/.scitex/scitex/local.srcOr install globally:
scitex mcp installDetected by scitex-linter when this package is installed.
