matplotlib学习整理

1. 安装

Once you have python up and running, you will need to install . 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、 下载一下这个东西！
we strongly encourage you to install
,
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)'.

3、 下载 它自己
