Low-level plotting library for full customisation. Use when you need fine-grained control over every plot element, creating novel plot types, or integrating with specific scientific workflows. Export to PNG/PDF/SVG for publication. For quick statistical plots use seaborn; for interactive plots use plotly; for publication-ready multi-panel figures with journal styling, use scientific-visualisation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Matplotlib ## Overview Matplotlib is Python's foundational visualisation library for creating static, animated, and interactive plots. This skill provides guidance on using matplotlib effectively, covering both the pyplot interface (MATLAB-style) and the object-oriented API (Figure/Axes), along with best practices for creating publication-quality visualisations. ## When to Use This Skill This skill should be used when: - Creating any type of plot or chart (line, scatter, bar, histogram, heatmap, contour, etc.) - Generating scientific or statistical visualisations - Customising plot appearance (colours, styles, labels, legends) - Creating multi-panel figures with subplots - Exporting visualisations to various formats (PNG, PDF, SVG, etc.) - Building interactive plots or animations - Working with 3D visualisations - Integrating plots into Jupyter notebooks or GUI applications ## Core Concepts ### The Matplotlib Hierarchy Matplotlib uses a hierarchical structure of objects: 1. **Figure** - The top-level container for all plot elements 2. **Axes** - The actual plotting area where data is displayed (one Figure can contain multiple Axes) …

How to install
mdr add marielynneblock/arcanum-artifex/matplotlib@sha256:4757126467bee57eThe line at the top of this page pins the label git:20260710.0115f49, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
