提问by H?kon H?gland
I am new to pythonand pyplot. I am trying to understand the documentation for the Matplotlib API related to the Figure Figure API.
我是python和 的新手pyplot。我试图了解与 Figure Figure API相关的 Matplotlib API 的文档。
In the beginning it says there is a class matplotlib.figure.AxesStack, and then
一开始它说有一个class matplotlib.figure.AxesStack，然后
The AxesStack is a callable, where ax_stack() returns the current axes
AxesStack 是可调用的，其中 ax_stack() 返回当前轴
When I try to use this in a program
当我尝试在程序中使用它时
import numpy as np
import matplotlib.pyplot as plt
n=4
v=np.arange(n)
X,Y = np.meshgrid(v,v)
Z=np.random.rand(n-1,n-1)
fig, ax = plt.subplots()
plt.pcolormesh(X, Y, Z)
plt.axis('tight')
plt.colorbar()
ast=fig.ax_stack()
plt.show()
I get error
我得到错误
AttributeError: 'Figure' object has no attribute 'ax_stack'
