【2.9.2】matplotlib.patches.Polygon
一、案例
import matplotlib.pyplot as plt
from matplotlib.patches import Ellipse, Polygon
fig, (ax1, ax2, ax3) = plt.subplots(3)
ax1.bar(range(1, 5), range(1, 5), color='red', edgecolor='black', hatch="/")
ax1.bar(range(1, 5), [6] * 4, bottom=range(1, 5),
color='blue', edgecolor='black', hatch='//')
ax1.set_xticks([1.5, 2.5, 3.5, 4.5])
bars = ax2.bar(range(1, 5), range(1, 5), color='yellow', ecolor='black') + \
ax2.bar(range(1, 5), [6] * 4, bottom=range(1, 5),
color='green', ecolor='black')
ax2.set_xticks([1.5, 2.5, 3.5, 4.5])
patterns = ('-', '+', 'x', '\\', '*', 'o', 'O', '.')
for bar, pattern in zip(bars, patterns):
bar.set_hatch(pattern)
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()
二、说明
class matplotlib.patches.Polygon(xy, closed=True, **kwargs)
- 通过xy来传递一系列坐标点
- 当closed=True的时候,当起始和终止位点一样时,polygon将会关闭
- Polygon构建的多边形,需要通过add_patch来添加到图中
