Axes3d的3D绘图无法执行

Question

当我尝试在pycharm中绘制3D对象时，我收到此错误：

TypeError: 'module' object is not callable

代码结构：

# visualizing data with pyplot
#usings
import numpy as np
import matplotlib.pyplot as plt
import urllib
from mpl_toolkits.mplot3d import axes3d
#main code
fig=plt.figure()
ax=axes3d(fig)
t=np.linspace(0,5*np.pi,501)
ax.plot(np.cos(t),np.sin(t),t)
plt.show()

Answer 1

参见工作代码示例here。

我为ax=axes3d(fig)交换了ax=axes3d(fig)行，但运行正常。

import numpy as np
import matplotlib.pyplot as plt

from mpl_toolkits.mplot3d import axes3d
#main code
fig=plt.figure()
ax = fig.gca(projection='3d')
t=np.linspace(0,5*np.pi,501)
ax.plot(np.cos(t),np.sin(t),t)
plt.show()
