matplotlib · davila7 — Claude Code skill: plots and publication figures

Q: How do I install the matplotlib skill in Claude?

Use the templates command: `npx claude-code-templates@latest --skill scientific/matplotlib`. Or pull it straight from the repo: `npx skills add davila7/claude-code-templates --skill matplotlib -a claude-code`.

A Claude skill for matplotlib: line plots, scatter, bar, histograms, heatmaps and 3D figures, exported to PNG, PDF or SVG.

What matplotlib does

The skill teaches the agent how to use matplotlib: the pyplot interface in MATLAB style and the object-oriented Figure/Axes API, the object hierarchy, plot types and saving figures. It ships code samples for line plots, scatter, bar charts, histograms, heatmaps, contours, box and violin plots, plus 3D through mpl_toolkits.mplot3d.

Multi-panel layouts get their own section: a plain plt.subplots grid, subplot_mosaic and GridSpec when you need full control. Styling covers named colors, hex codes, RGB tuples, colormaps such as viridis and coolwarm, style sheets and rcParams tweaks. Export goes through plt.savefig with dpi, bbox_inches='tight' and transparent.

The examples assume Python with matplotlib and numpy installed, so drop the skill into a project that already has both. For publication figures the guidance points to dpi=300, for web output 150. If your charts come from a different library, the extra hints just add noise for the agent.

What it helps with

plot a time series with labeled axes
build a four-panel grid mixing plot types
render a correlation matrix as a heatmap with a colorbar
export a figure to PDF for a paper
draw a 3D surface from X, Y, Z arrays

Example prompts for the agent

plot sin(x) and cos(x) on one Axes with a legend and grid
make a 2x2 figure with line, scatter, bar and histogram, save it as PNG at dpi=300
draw a heatmap of the matrix with imshow, colormap coolwarm, and add a colorbar

Questions about matplotlib

How do I install the matplotlib skill in Claude?

Use the templates command: npx claude-code-templates@latest --skill scientific/matplotlib. Or pull it straight from the repo: npx skills add davila7/claude-code-templates --skill matplotlib -a claude-code.

What does the matplotlib skill do?

It guides the agent through matplotlib plotting, from simple line charts to 3D, with styling options and export to PNG, PDF and SVG.

What do I need for the skill to work?

Python with matplotlib and numpy installed — the samples use both packages.
