import numpy as np
import matplotlib.pyplot as plt
from matplotlib.pyplot import MultipleLocator
ax = plt.axes(projection='3d')
ax.patch.set_alpha(0)
# 定义坐标轴
xx = np.arange(-5, 5, 0.1)
yy = np.arange(-5, 5, 0.1)
X, Y = np.meshgrid(xx, yy)
Z = np.sin(np.sqrt(X**2+Y**2))
# 作图
ax.plot_surface(X, Y, Z, cmap='cividis') # cividis pink_r summer viridis winter Greens Pastel1 YlGn
ax.contour(X, Y, Z, zdir='z', offset=-1, cmap="cividis")
# 设置坐标间隔
ax.set_zlim(-1, 1, 0.5)
ax.zaxis.set_major_locator(MultipleLocator(0.5))
# 设置视角
ax.view_init(30, 45)
# 设置边界
plt.subplots_adjust(left=0, bottom=0, right=1, top=1)
plt.show()
