Dash join style

Example demoing the dash join style.

import numpy as np
import matplotlib.pyplot as plt

size = 256, 16
dpi = 72.0
figsize = size[0] / float(dpi), size[1] / float(dpi)
fig = plt.figure(figsize=figsize, dpi=dpi)
fig.patch.set_alpha(0)
plt.axes((0, 0, 1, 1), frameon=False)

plt.plot(
    np.arange(3),
    [0, 1, 0],
    color="blue",
    dashes=[12, 5],
    linewidth=8,
    dash_joinstyle="miter",
)
plt.plot(
    4 + np.arange(3),
    [0, 1, 0],
    color="blue",
    dashes=[12, 5],
    linewidth=8,
    dash_joinstyle="bevel",
)
plt.plot(
    8 + np.arange(3),
    [0, 1, 0],
    color="blue",
    dashes=[12, 5],
    linewidth=8,
    dash_joinstyle="round",
)

plt.xlim(0, 12)
plt.ylim(-1, 2)
plt.xticks([])
plt.yticks([])

plt.show()
