# mplhep-data — Font (Data) sub-package for mplhep

License: permissive · Maintenance: active · Downloads: 351.3K/mo

## What it is and what it does

mplhep_data is a data package that bundles fonts and related assets for the mplhep scientific plotting library. It contains four open-licensed typefaces—Tex Gyre Heros, Tex Gyre Termes, Fira Sans, and Fira Math—packaged for convenient distribution rather than requiring users to download them separately from multiple sources.

The package has no runtime dependencies and installs as a lightweight wheel. It is maintained as part of the Scikit-HEP project and supports Python 3.10 through 3.14. Its primary role is to ensure that mplhep users have consistent, redistributable fonts available without manual setup.

Use it for:

- Installing fonts needed by mplhep for high-energy physics plotting and visualization.
- Ensuring consistent typography across scientific plots in Jupyter notebooks or batch analysis pipelines.
- Bundling with mplhep in environments where downloading fonts from external sources is inconvenient or restricted.
- Providing Fira Math and Tex Gyre typefaces to Python plotting workflows that require specific font families.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Distributes fonts and data files for the mplhep plotting library, including Tex Gyre Heros, Tex Gyre Termes, Fira Sans, and Fira Math with open licenses.

Yes, if you use mplhep for scientific plotting. It is a lightweight, dependency-free package with permissive licensing and no known vulnerabilities. Install it as a companion to mplhep to ensure fonts are available. If mplhep is not in your workflow, this package has no standalone value.

## Install

pip install mplhep-data
uv add mplhep-data
poetry add mplhep-data

## Installing mplhep-data

Before you install: Low friction: pure Python wheel with no runtime dependencies. Active maintenance with recent release (71 days ago). Early development status (Planning) but supported on modern Python versions 3.10–3.14.

License in practice: MIT license permits free use, modification, and redistribution with minimal restrictions. Fonts included have open licenses and can be redistributed.

Quickstart:

pip install mplhep-data

import mplhep_data
# Fonts are now available for use by mplhep or direct access

Requires Python 3.10 or later.

Verify before relying:

- How mplhep_data integrates with mplhep itself and whether it must be installed separately or is pulled in automatically.
- Whether the included fonts can be accessed programmatically or are only available to mplhep's plotting functions.
- Font coverage: which specific font weights, styles, or variants are included for each typeface.
