ipython pandas plot does not show
提问by cantdutchthis
I am using the anaconda distribution of ipython/Qt console. I want to plot things inline so I type the following from the ipython console:
我正在使用 ipython/Qt 控制台的 anaconda 发行版。我想内联绘制内容，所以我从 ipython 控制台输入以下内容：
%pylab inline
Next I type the tutorial at (http://pandas.pydata.org/pandas-docs/dev/visualization.html) into ipython...
接下来，我将 ( http://pandas.pydata.org/pandas-docs/dev/visualization.html) 上的教程输入 ipython ...
import matplotlib.pyplot as plt
import pandas as pd
ts = pd.Series(randn(1000), index = pd.date_range('1/1/2000', periods=1000))
ts = ts.cumsum()
ts.plot()
... and this is all that i get back:
...这就是我要回来的全部内容：
<matplotlib.axes.AxesSubplot at 0x109253410>
But there is no plot. What could be wrong? Is there another command that I need to supply? The tutorial suggests that that is all that I need to type.
但是没有情节。可能有什么问题？我需要提供另一个命令吗？该教程表明这就是我需要输入的全部内容。

Plots are not displayed until you run
在您运行之前不会显示图
plt.show()
plt.show()

There could be 2 ways to approach this problem:
可能有两种方法来解决这个问题：
1) Either invoke the inline/osx/qt/gtk/gtk3/tk backend. Depends on the ipython console that you have been using. So, simply do:
1) 要么调用 inline/osx/qt/gtk/gtk3/tk 后端。取决于您一直使用的 ipython 控制台。因此，只需执行以下操作：
%matplotlib inline#Here the inline backend is invoked, which removes the necessity of calling show after each plot.
%matplotlib inline#这里调用了内联后端，这消除了在每个绘图之后调用 show 的必要性。
or for ipython/qt console, do:
或者对于 ipython/qt 控制台，请执行以下操作：
%matplotlib qt#This one works for me, thus, depends on the ipython console you use.
%matplotlib qt#这个对我有用，因此，取决于你使用的 ipython 控制台。
#
#
2) Or, do the traditional way as aforementioned(already answered above on this page):
2）或者，按照前面提到的传统方式（已经在本页上面回答）：
plt.show()#However, you will have to call this show function each time.
plt.show()#但是，您每次都必须调用此 show 函数。
