Linux, Matplotlib related issues and workarounds

1. When running the Matplotlib program under Linux, install the matplotlib.

Continue with the installation according to different Linux systems:

Debian/ubuntu:sudo apt-get install python-matplotlib

Fedora/redhat:sudo yum install python-matplotlib

2. Run the Matplotlib program times with the following error:

Solution, add the following code to the file header

import matplotlib

matplotlib.use(‘Agg‘)


3. Generated picture, cannot display Chinese, show square in picture

Workaround:

1. In Ubutu, confirm the existing Chinese font library in the system:
$ fc-list :lang=zh
2. Terminal display:

$ fc-list :lang=zh 

/usr/share/fonts/truetype/droid/DroidSansFallbackFull.ttf: Droid Sans Fallback:style=Regular

Can see only one font, Droid Sans Fallback

2. 在脚本中添加代码

import matplotlib as mpl

mpl.rcParams[‘font.sans-serif‘] = [‘Droid Sans Fallback‘]

3. Configuration of the Matplotlibrc file

Under Linux, go to the python command prompt:

Import Matplotlib

Matplotlib.matplotlib_fname ()

It will then print out where the Matplotlibrc file is located, and the default location (/etc) is probably the case:

such as: U '/usr/local/lib/python2.7/dist-packages/matplotlib-1.5.1-py2.7-linux-i686.egg/matplotlib/mpl-data/ MATPLOTLIBRC '

Open this file with administrator privileges and find

#font. Serif:
#font. Family:

The two lines, uncomment it, save.
