Python Pandas figsize not defined
提问by wuha
I am new to pandas for data analysis and I just installed pandas with required dependencies (NumPy, python-dateutil, pytz, numexpr, bottleneck and matplotlib). But when I started trying the most basic code:
我是 Pandas 的新手进行数据分析，我刚刚安装了具有所需依赖项（NumPy、python-dateutil、pytz、numexpr、bottleneck 和 matplotlib）的 Pandas。但是当我开始尝试最基本的代码时：
import pandas as pd
pd.set_option('display.mpl_style', 'default') # Make the graphs a bit prettier
figsize(15, 5)
It complains NameError: name 'figsize' is not defined.
它抱怨 NameError: name 'figsize' is not defined。
I am not sure if I still need some other dependencies. Could anyone shed some light on this?
我不确定是否还需要其他一些依赖项。任何人都可以对此有所了解吗？

Try using %pylabif %pylab inlinedoes not work.
尝试使用%pylabif %pylab inline不起作用。
So it should be:
所以应该是：
%pylab
import pandas as pd
pd.set_option('display.mpl_style', 'default') # Make the graphs a bit prettier
figsize(15, 5)
The example is based on running the code in Ipython using Ipython magic command %pylabwhich gives you:
该示例基于使用 Ipython 魔术命令在 Ipython 中运行代码，该命令%pylab为您提供：
In [16]: %pylab
Using matplotlib backend: TkAgg
Populating the interactive namespace from numpy and matplotlib
If you are not using Ipython and the %pylabmagic you will have to use something like:
如果你没有使用 Ipython 和%pylab魔法，你将不得不使用类似的东西：
from pylab import *
rcParams['figure.figsize'] = 15,5
If you have Ipython-notebook istalled you can start it with pylab inline using:
如果您安装了 Ipython-notebook，您可以使用 pylab 内联方式启动它：
ipython notebook --pylab inline from the command line.
I would recommend using Ipython to start with.
我建议使用 Ipython 开始。

When I got the same problem I changed figsize() from function call to assignment figsize = (15,5)
And it worked for me.
当我遇到同样的问题时，我将 figsize() 从函数调用更改为赋值 figsize = (15,5)
并且它对我有用。

You might be using an earlier version of pandas. The function figsize()may have been introduced in a later version.
您可能使用的是早期版本的Pandas。该功能figsize()可能已在更高版本中引入。
In version 1.13 I achieved something similar with a statement like df.plot(figsize=(15, 5))
在 1.13 版中，我用类似的语句实现了类似的功能 df.plot(figsize=(15, 5))

using VarianleName.plot(figszie=(n,n)will solve the problem
n,ncould be numberslike 15,10
使用VarianleName.plot(figszie=(n,n)将解决问题
n,n可能numbers就像15,10
