问题：在Ipython notebook / Jupyter中，Pandas未显示我尝试绘制的图形
我正在尝试使用Ipython Notebook中的熊猫绘制一些数据，尽管它给了我对象，但实际上并没有绘制图形本身。所以看起来像这样：
In [7]:
pledge.Amount.plot()
Out[7]:
<matplotlib.axes.AxesSubplot at 0x9397c6c>
该图应在此之后，但根本不会出现。我已经导入了matplotlib，所以这不是问题。我还需要导入其他模块吗？
I am trying to plot some data using pandas in Ipython Notebook, and while it gives me the object, it doesn’t actually plot the graph itself. So it looks like this:
In [7]:
pledge.Amount.plot()
Out[7]:
<matplotlib.axes.AxesSubplot at 0x9397c6c>
The graph should follow after that, but it simply doesn’t appear. I have imported matplotlib, so that’s not the problem. Is there any other module I need to import?

请注意，–pylab已被弃用，并且已从较新的IPython版本中删除。建议在IPython Notebook中启用内联绘图的方法现已运行：
%matplotlib inline
import matplotlib.pyplot as plt
有关更多详细信息，请参阅ipython-dev邮件列表中的这篇文章。
Note that –pylab is deprecated and has been removed from newer builds of IPython, The recommended way to enable inline plotting in the IPython Notebook is now to run:
%matplotlib inline
import matplotlib.pyplot as plt
See this post from the ipython-dev mailing list for more details.

编辑：Pylab已被弃用，请参阅当前接受的答案
好的，看来答案是使用–pylab = inline启动ipython Notebook。因此，ipython notebook –pylab = inline可以完成我之前看到的以及我想要它做的事情。对不起这个原始的问题。
Edit:Pylab has been deprecated please see the current accepted answer
Ok, It seems the answer is to start ipython notebook with –pylab=inline.
so ipython notebook –pylab=inline
This has it do what I saw earlier and what I wanted it to do.
Sorry about the vague original question.

与您import matplotlib.pyplot as plt只需添加
plt.show()
它将显示所有存储的图。
With your import matplotlib.pyplot as plt just add
plt.show()
and it will show all stored plots.

导入matplotlib之后很简单，如果像这样启动ipython，就可以执行一个魔术
ipython notebook

运行此命令，一切都会完美显示
simple after importing the matplotlib you have execute one magic if you have started the ipython as like this

使用来启动ipython ipython notebook --pylab inline，然后图形将内联显示。
start ipython with ipython notebook --pylab inline ,then graph will show inline.
