复合路径
制作复合路径 - 在这种情况下是两个简单的多边形,一个矩形和一个三角形。使用 CLOSEPOLY 和 MOVETO 作为复合路径的不同部分。

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)]
vertices = np.array(vertices, float) 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()
