Hatch演示

目前仅在PS，PDF，SVG和Agg后端支持阴影线（图案填充多边形）。

  1. import matplotlib.pyplot as plt
  2. from matplotlib.patches import Ellipse, Polygon
  4. fig, (ax1, ax2, ax3) = plt.subplots(3)
  6. ax1.bar(range(1, 5), range(1, 5), color='red', edgecolor='black', hatch="/")
  7. ax1.bar(range(1, 5), [6] * 4, bottom=range(1, 5),
  8.         color='blue', edgecolor='black', hatch='//')
  9. ax1.set_xticks([1.5, 2.5, 3.5, 4.5])
  11. bars = ax2.bar(range(1, 5), range(1, 5), color='yellow', ecolor='black') + \
  12.     ax2.bar(range(1, 5), [6] * 4, bottom=range(1, 5),
  13.             color='green', ecolor='black')
  14. ax2.set_xticks([1.5, 2.5, 3.5, 4.5])
  16. patterns = ('-', '+', 'x', '\\', '*', 'o', 'O', '.')
  17. for bar, pattern in zip(bars, patterns):
  18.     bar.set_hatch(pattern)
  20. ax3.fill([1, 3, 3, 1], [1, 1, 2, 2], fill=False, hatch='\\')
  21. ax3.add_patch(Ellipse((4, 1.5), 4, 0.5, fill=False, hatch='*'))
  22. ax3.add_patch(Polygon([[0, 0], [4, 1.1], [6, 2.5], [2, 1.4]], closed=True,
  23.                       fill=False, hatch='/'))
  24. ax3.set_xlim((0, 6))
  25. ax3.set_ylim((0, 2.5))
  27. plt.show()
