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 "", line 1, in File "G:\Python27\lib\site-packages\matplotlib\__init__.py", line 105, in 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 "", line 1, in File "G:\Python27\lib\site-packages\matplotlib\__init__.py", line 116, in 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 Searching for python-dateutil Best match: python-dateutil 2.2 Processing python_dateutil-2.2-py2.7.egg Adding python-dateutil 2.2 to easy-install.pth file
Using g:\python27\lib\site-packages\python_dateutil-2.2-py2.7.egg Processing dependencies for python-dateutil Searching for six Reading https://pypi.python.org/simple/six/ Download error on https://pypi.python.org/simple/six/: _ssl.c:495: The handshake operation timed out -- Some packages may not be found! Couldn't find index page for 'six' (maybe misspelled?) Scanning index of all packages (this may take a while) Reading https://pypi.python.org/simple/ error: The read operation timed out
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 Type "help", "copyright", "credits" or "license" for more information. >>> import matplotlib Traceback (most recent call last): File "", line 1, in File "G:\Python27\lib\site-packages\matplotlib\__init__.py", line 140, in 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 Python 2.7.8 (default, Jun 30 2014, 16:03:49) [MSC v.1500 32 bit (Intel)] on win 32 Type "help", "copyright", "credits" or "license" for more information. >>> 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]) [] >>> plt.ylabel('some numbers') >>> plt.show()
测试
