贝塞尔曲线#
此示例展示了PathPatch创建 Bezier 多曲线路径补丁的对象。
import matplotlib.path as mpath
import matplotlib.patches as mpatches
import matplotlib.pyplot as plt
Path = mpath.Path
fig, ax = plt.subplots()
pp1 = mpatches.PathPatch(
Path([(0, 0), (1, 0), (1, 1), (0, 0)],
[Path.MOVETO, Path.CURVE3, Path.CURVE3, Path.CLOSEPOLY]),
fc="none", transform=ax.transData)
ax.add_patch(pp1)
ax.plot([0.75], [0.25], "ro")
ax.set_title('The red point should be on the path')
plt.show()
