dufte 0.2.27

Clean matplotlib plots

Da kiekste, wa?

This package creates clean and beautiful plots that work on light and dark backgrounds. Inspired by the work of Edward Tufte.

To use, simply select the dufte style:

import dufte
import matplotlib.pyplot as plt

# global setting:
plt.style.use(dufte.style)

# with a context manager:
with plt.style.context(dufte.style_bar):
    # ...
    pass

Check out dufte.legend(), dufte.ylabel(), and dufte.show_bar_values() for more duftiness.

Comparison with default Matplotlib

See here for how to create the below plots.

Background

The position $x_i$ of the line annotations is computed as the solution of a non-negative least-squares problem

\begin{align}
\frac{1}{2}\sum_i (x_i - t_i)^2 \to \min_x,\\
(x_i - x_j)^2 \ge a^2 \quad \forall i,j.
\end{align}

where $a$ is the minimum distance between two entries and $t_i$ is the target position.
