複合路徑#

建立複合路徑 - 在此範例中為兩個簡單的多邊形,一個矩形和一個三角形。使用 CLOSEPOLYMOVETO 來表示複合路徑的不同部分

import matplotlib.pyplot as plt

from matplotlib.patches import PathPatch
from matplotlib.path import Path

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
