는, 당신은 FancyArrowPatch에서 상속 및 화살촉과 선 그리기에 대한 책임 클래스를 만들 수 있습니다 당신은 그들에게이 그들에 따르면 멋진 Putting arrowheads on vectors in matplotlib's 3d plot 의 예와 Python/matplotlib : plotting a 3d cube, a sphere and a vector?
에 있습니다.
전체 코드는 다음과 같을 수 있습니다 :
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
from matplotlib.patches import FancyArrowPatch
import numpy as np
from mpl_toolkits.mplot3d import proj3d
class Arrow3D(FancyArrowPatch):
def __init__(self, xs, ys, zs, *args, **kwargs):
FancyArrowPatch.__init__(self, (0, 0), (0, 0), *args, **kwargs)
self._verts3d = xs, ys, zs
def draw(self, renderer):
xs3d, ys3d, zs3d = self._verts3d
xs, ys, zs = proj3d.proj_transform(xs3d, ys3d, zs3d, renderer.M)
self.set_positions((xs[0], ys[0]), (xs[1], ys[1]))
FancyArrowPatch.draw(self, renderer)
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
# lines were replaced by Arrow3D below, so they might be no longer needed
# ax.plot([0,0.7], [0,0.5],zs=[1,1])
# ax.plot([0,-0.3], [0,0.7],zs=[2,2])
# ax.plot([0,-0.3],[0,0],zs=[3,3])
ax.set_xlim([0, 3])
ax.set_ylim([3, 0])
ax.set_zlim([0, 4])
a = Arrow3D([0, 0.7], [0, 0.5], [1, 1], mutation_scale=20, lw=1, arrowstyle="->", color="b")
b = Arrow3D([0, -0.3], [0, 0.7], [2, 2], mutation_scale=20, lw=1, arrowstyle="->", color="r")
c = Arrow3D([0, -0.3], [0, 0], [3, 3], mutation_scale=20, lw=1, arrowstyle="->", color="g")
ax.add_artist(a)
ax.add_artist(b)
ax.add_artist(c)
plt.show()
