This article will explain in detail how to do Chinese garbled code in matplotlib under the ubuntu system. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

When drawing with matplotlib under ubuntu, Chinese can not be displayed on the image. Here is my solution:

1. Download Chinese font simhei.ttf at http://fontzone.net/download/simhei

two。 Search the location where matplotlib fonts are installed

$locate-b'\ mpl-data'

You will get the fonts/ttf directory under the path / usr/share/matplotlib/mpl-data, enter this directory, copy the simhei.ttf font you just downloaded to this directory, and pay attention to whether the permissions and attribution are the same as other fonts. Mine belongs to the root user, so use the root user to copy it over.

3. Delete the buffer file of the current user matplotlib (if you do not proceed directly to step 4)

$cd ~ / .cache/matplotlib$rm-rf *.

4. Adjust the font in the code

#! / usr/bin/env python#coding:utf-8 "" a demo of matplotlib "" import matplotlib as mplfrom matplotlib import pyplot as pltmpl.rcParams [u 'font.sans-serif'] = ['simhei'] mpl.rcParams [' axes.unicode_minus'] = Falseyears = [1950, 1960, 1970, 1980, 1990, 2000, 2010] gdp = [300.2, 543.3, 1075.9, 2862.5, 5979.6, 10289.7, 14958.3] # create a pair of diagrams with the x axis being the year The y-axis is gdpplt.plot (years, gdp, color='green', marker='o', linestyle='solid') # add a title plt.title (u 'nominal GDP') # mark the y-axis plt.ylabel (u' billion dollars') plt.show ()

Where # coding:utf-8 description file encoding format

Mpl.rcParams [u 'font.sans-serif'] = [' simhei'] displays Chinese in simhei font

Mpl.rcParams ['axes.unicode_minus'] = False this is used to display negative signs normally.

Plt.title (u 'nominal GDP') the u here had better not be less.
