三維表面圖

Draw a 3D surface map Z = sin ⁡ ( x 2 + y 2 ) \text{Draw a 3D surface map}Z=\sin \left( \sqrt{x^2+y^2} \right) Draw a 3D surface mapZ=sin(x2+y2​)

import pylab as plt
import numpy as np
ax=plt.axes(projection="3d")
X=np.arange(-6,6,0.25)
Y=np.arange(-6,6,0.25)
X,Y=np.meshgrid(X,Y)
Z=np.sin(np.sqrt(X**2+Y**2))
surf=ax.plot_surface(X,Y,Z,cmap="coolwarm")
plt.colorbar(surf)
plt.show()

三維曲線圖

Draw a 3D surface graph Z = 50 sin ⁡ ( x + y ) \text{Draw a 3D surface graph}Z=50\sin \left( x+y \right) Draw a 3D surface graphZ=50sin(x+y)

import pylab as plt
import numpy as np
x=np.linspace(-4,4,100)
x,y=np.meshgrid(x,x)
z=50*np.sin(x+y)
ax=plt.axes(projection="3d")
ax.plot_surface(x,y,z,cmap="coolwarm")
plt.show()
