如何绘制2d平面，x轴范围从0到1，y轴范围从0到1，z轴0

Question

I am trying to plot a 3d vector space like this

here is the code

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.quiver(0, 0, 0, 0, 1, 0)
ax.quiver(0, 0, 0, 1, 0, 0)
ax.quiver(0, 0, 0, 0, 0, 1)
ax.quiver(0, 0, 0, 1, 1, 1)

limt = 2
ax.set_xlim([-limt, limt])
ax.set_ylim([-limt, limt])
ax.set_zlim([-limt, limt])

ax.set_xlabel('x_axis')
ax.set_ylabel('y_axis')
ax.set_zlabel('z_axis')
plt.show()

I've finished the vectors (a line with an arrow) part, how can I plot a 2d plane x axis range from 0 to 1, y axis range from 0 to 1, and z axis 0?

Answer 1

plot_surface may meet your need.

xx, yy = np.meshgrid(np.arange(0,1,.1), np.arange(0,1,.1))
zz = np.zeros((10,10))
ax.plot_surface(xx, yy, zz, alpha=0.5)
