Installation of the Python drawing library matplotlib

This article briefly describes the installation of the Python drawing library matplotlib, as follows:

Matplotlib is Python's most famous drawing library, which provides a complete set of command APIs similar to those of MATLAB, and is ideal for interactive
For mapping. Matplotlib installation can be found at: Website Link http://matplotlib.org/users/installing.html

The installation summary steps are as follows:

The Windows platform downloads the. exe format to install directly.

1.python Download Install download address: http://www.python.org/download/.
2. Install the version you need (this will be based on the Python version of Step 1) matplotlib, download address: http://matplotlib.org/downloads.html.
Install the Matplotlib dependent libraries below
3. For the standard version of Python, to use Matplotlib, you will also need to install the NumPy module with the download address: http://sourceforge.net/projects/numpy/files/NumPy/.
4.msvcp71.dll, on some systems, you may also need to download the Msvcp71.dll library. Download Address: http://www.dll-files.com/dllindex/dll-files.shtml?msvcp71
Download the extract and drag it to the C:\Windows\System32 directory.
5. Run a simple program example:

View Plaincopy on code to see a snippet derived from my Code slice

Import Matplotlib.pyplot as Plt Plt.plot ([]) Plt.ylabel (' Some numbers ') plt.show ()

Errors encountered during the installation
The following error was found:
Raise Importerror ("Matplotlib requires Dateutil")
Importerror:matplotlib requires Dateutil
This needs dateutil, you can download the installation here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-dateutil.

After installing the Dateutil, the following error occurred:
Raise Importerror ("Matplotlib requires pyparsing")
Importerror:matplotlib requires pyparsing
Need pyparsing here to download installation: http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyparsing.

Complete the above steps and run the example above to display our images as shown below.

If you encounter some dependencies that you need to install during the program installation, you can find http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyparsing here, which is indeed a good resource.

According to the need to draw the graphics in the following link to select the corresponding graphic to modify, to draw their own images required.

How to solve Chinese garbled characters

Note the resolution for Chinese in drawing, add the following to the header of the. py file:

#-*-Coding:utf-8-*-from pylab import * mpl.rcparams[' font.sans-serif '] = [' Simhei '] #指定默认字体 mpl.rcparams[' axes.unicod E_minus '] = False #解决保存图像是负号 '-' is displayed as a block problem

Drawing script. py to. exe

If you want to be able to publish a Python script as an executable program running out of the Python platform, such as a single EXE file. You can refer to this blog post: http://blog.csdn.net/daniel_ustc/article/details/15501385

Using a portable Python environment

Python programming language under the mobile device operating environment and programming language environment, portable Python is a Python programming language pre-run directly from any USB storage device, so that at any time you have a portable programming environment. It is very convenient to make it up, recommended to use.
