复合路径

创建一个复合路径——在本例中是两个简单的多边形,一个矩形和一个三角形。使用 CLOSEPOLYMOVETO 对于复合路径的不同部分

from matplotlib.path import Path
from matplotlib.patches import PathPatch
import matplotlib.pyplot as plt

vertices = []
codes = []

codes = [Path.MOVETO] + [Path.LINETO]*3 + [Path.CLOSEPOLY]
vertices = [(1, 1), (1, 2), (2, 2), (2, 1), (0, 0)]

codes += [Path.MOVETO] + [Path.LINETO]*2 + [Path.CLOSEPOLY]
vertices += [(4, 4), (5, 5), (5, 4), (0, 0)]

path = Path(vertices, codes)

pathpatch = PathPatch(path, facecolor='None', edgecolor='green')

fig, ax = plt.subplots()
ax.add_patch(pathpatch)
ax.set_title('A compound path')

ax.autoscale_view()

plt.show()
A compound path

工具书类

以下函数、方法、类和模块的使用如本例所示:

出:
