matplotlib学习整理

1. 安装
http://matplotlib.sourceforge.net/users/installing.html
Once you have python up and running, you will need to install
numpy
.
numpy provides high performance array data structures and mathematical
functions, and is a requirement for matplotlib.  You can test your
progress:
>>> import numpy
>>> print numpy.__version__
1、下载这个东西下来是为了使用一些内置的数学函数的～
matplotlib requires numpy version 1.1 or later
一开始下载错了。不过现 在好了！
奇怪哦好像还 要配置一下环境变量什么 的！
2、http://ipython.scipy.org/dist/ 下载一下这个东西！
we strongly encourage you to install
ipython
,
which is an interactive shell for python that is matplotlib aware.我下载下来了！
Once you have ipython,
numpy and matplotlib installed, in ipython’s “pylab” mode you have a
matlab-like environment that automatically handles most of the
configuration details for you, so you can get up and running quickly:
johnh@flag:~> ipython -pylab
Python 2.4.5 (#4, Apr 12 2008, 09:09:16)
IPython 0.9.0 -- An enhanced Interactive Python.
  Welcome to pylab, a matplotlib-based Python environment.
  For more information, type 'help(pylab)'.
In [1]: x = randn(10000)
3、http://sourceforge.net/projects/matplotlib/files/ 下载 它自己
！
In [2]: hist(x, 100)
