python matplotlib 实战安装 初体验

相比pychart，使用matplotlib更合适。

1、网上下载matplotlib-1.1.0.win32-py2.7.exe 下载地址为     http://matplotlib.org/downloads.html
    numpy-1.8.1-win32-superpack-python2.7.exe
        
2、之前在笔记本电脑path中定义了两个python的路径，结果安装matplotlib-1.1.0.win32-py2.7.exe
numpy-1.8.1-win32-superpack-python2.7.exe 一直出错。
修改重新定义windows的环境变量path 唯一定义python，安装OK

3、import numpy as  np 成功

4、执行 import matplotlib.pyplot as plt 出错
>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "G:\Python27\lib\site-packages\matplotlib\__init__.py", line 105, in <mod
ule>
    import six
ImportError: No module named six
>>>
import matplotlib

5、下载安装scipy
http://www.onlinedown.net/softdown/107395_2.htm

6、把C:\Python27\Lib\site-packages\scipy\lib中的six.py six.pyc 2个文件拷贝到C:\Python27\Lib\site-packages目录下

。
7、>>> import matplotlib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "G:\Python27\lib\site-packages\matplotlib\__init__.py", line 116, in <mod
ule>
    raise ImportError("matplotlib requires dateutil")
ImportError: matplotlib requires dateutil

8、这个需要dateutil，http://www.lfd.uci.edu/~gohlke/pythonlibs/

使用easy_install下载安装

打开cmd,命令行，进入到Python\Scripts目录下，这个目录下执行easy_install python-dateutil，
既可以安装dateutil这个模块，
easy_install pyparsing就可以安装pyparsing这个模块

G:\Python27\Scripts>easy_install python-dateutil

9、验证 import matplotlib
G:\Python27\Scripts>python
Python 2.7.8 (default, Jun 30 2014, 16:03:49) [MSC v.1500 32 bit (Intel)] on win
32

>>> import matplotlib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "G:\Python27\lib\site-packages\matplotlib\__init__.py", line 140, in <mod
ule>
    raise ImportError("matplotlib requires pyparsing")
ImportError: matplotlib requires pyparsing
>>>

10、下载安装pyparsing模块 http://pan.baidu.com/s/1pJx3THp
验证 import matplotlib
 
G:\Python27\Scripts>python

>>> import matplotlib
>>>

11、全部安装完成 matplotlib ok

import matplotlib.pyplot as plt 
 plt.plot([1,2,3]) 
 plt.ylabel('some numbers') 
 plt.show() 

>>> import matplotlib.pyplot as plt
>>>
>>> plt.plot([1,2,3])
[<matplotlib.lines.Line2D object at 0x03394610>]
>>> plt.ylabel('some numbers')
<matplotlib.text.Text object at 0x0316F950>
>>> plt.show()
