Hatch Demo

Hatching (pattern filled polygons) is supported currently in the PS, PDF, SVG and Agg backends only.

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.patches import Ellipse, Polygon

x = np.arange(1, 5)
y1 = np.arange(1, 5)
y2 = np.ones(y1.shape) * 4

fig, (ax1, ax2, ax3) = plt.subplots(3)

ax1.bar(x, y1, edgecolor='black', hatch="/")
ax1.bar(x, y2, bottom=y1, edgecolor='black', hatch='//')
ax1.set_xticks([1.5, 2.5, 3.5, 4.5])

ax2.bar(x, y1, edgecolor='black', hatch=['-', '+', 'x', '\\'])
ax2.bar(x, y2, bottom=y1, edgecolor='black', hatch=['*', 'o', 'O', '.'])
ax2.set_xticks([1.5, 2.5, 3.5, 4.5])

ax3.fill([1, 3, 3, 1], [1, 1, 2, 2], fill=False, hatch='\\')
ax3.add_patch(Ellipse((4, 1.5), 4, 0.5, fill=False, hatch='*'))
ax3.add_patch(Polygon([[0, 0], [4, 1.1], [6, 2.5], [2, 1.4]], closed=True,
                      fill=False, hatch='/'))
ax3.set_xlim((0, 6))
ax3.set_ylim((0, 2.5))

plt.show()
