Jupyter标记z轴时出现名称错误

Question

I have the following block of code to produce a 3D plot of sets of data:

figure(figsize=(20, 15))
ax = gca(projection="3d")
ax.plot_wireframe(X, Y, Z)
xlabel("x")
ylabel("y")
zlabel("z")
show()

However, an error is made when labelling the z-axis:

---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
<ipython-input-34-987e9d2dec12> in <module>()
      4 xlabel("x")
      5 ylabel("y")
----> 6 zlabel("z")
      7 show()

NameError: name 'zlabel' is not defined

I defined the z-axis using the following code earlier:

def z(x, y):

    b = 0.5**(x**2+y**2)
    return sin(b)

Z_data = z(X, Y)

I can't see what the problem appears to be. What is the issue?

Answer 1

As I am calling ax = gca() it seemed appropriate to use the ax method.

Hence, discovering on google that ax.set_zlabel('z') also managed to do the job gave me the solution I needed.
