charite-plot

A Python package with a Charité-styled Matplotlib theme, visual identity colour palettes, and an Altair theme — ported from the charite R package.

Visualize your data with theme_charite() to match the Charité corporate style.

Preview the available colour palettes.

Quick start

Matplotlib

import matplotlib.pyplot as plt
from charite_plot.mpl_themes import theme_charite, apply_theme

apply_theme(theme_charite())

fig, ax = plt.subplots()
ax.plot([1, 2, 3], [4, 7, 3])
ax.set_title("My chart")
plt.show()

Use as a context manager to scope the theme to a single figure:

from charite_plot.mpl_themes import theme_charite, using

with using(theme_charite(palette="goldelse")):
    fig, ax = plt.subplots()
    ax.bar(["A", "B", "C"], [3, 7, 5])

Altair

from charite_plot.altair_themes import enable
import altair as alt

enable()

chart = alt.Chart(df).mark_bar().encode(...)

Design principles

  • Single source of truth — colors are defined once in colors.py and imported by every other module.
  • No side effects on import — theme functions return plain dicts; you opt in with apply_theme(), using(), or enable().
  • Font fallback — if Charité Text Office is not installed, the theme cascades to Charit? Text Office, then Calibri, DejaVu Sans, and finally sans-serif automatically, following the official brand guidelines.
