Bezier曲线

此示例展示 PathPatch 对象以创建Bezier多曲线路径修补程序。

  1. import matplotlib.path as mpath
  2. import matplotlib.patches as mpatches
  3. import matplotlib.pyplot as plt
  5. Path = mpath.Path
  7. fig, ax = plt.subplots()
  8. pp1 = mpatches.PathPatch(
  9.     Path([(0, 0), (1, 0), (1, 1), (0, 0)],
  10.          [Path.MOVETO, Path.CURVE3, Path.CURVE3, Path.CLOSEPOLY]),
  11.     fc="none", transform=ax.transData)
  13. ax.add_patch(pp1)
  14. ax.plot([0.75], [0.25], "ro")
  15. ax.set_title('The red point should be on the path')
  17. plt.show()
