[Matplotlib-users] Display chinese labels

[Benoit G. <ben...@un...>]

Hi,

How can one display Mandarin labels in a plot, as yticks_labels for example?
It looks to me that there is no font in matplotlib that can display Chinese
characters? I can display accentuation from 'utf8' but i could not find a
font family that would display Chinese characters.

Here is an example of plot that displays empty boxes instead of Chinese
characters. In comments you can see various failed attempts:

import matplotlib as mpl
from matplotlib import cm
from matplotlib import rc
#rc('font',**{'family':'sans-serif','sans-serif':['SimHei','Arial']})
#mpl.rcParams['font.sans-serif'] = ['SimHei','Arial']
import matplotlib.pyplot as plt

matrix=[[skey+tkey for skey in [1,2]] for tkey in [1,2]]
fig = plt.figure()
axim = fig.add_subplot(111)
#ytics: caractères chinois en utf8
ytics=['\xe6\x8a\xb1'.decode('utf8'),'\xe6\x93\x81'.decode('utf8')]
xtics=['d\xc3\xa9bo\xc3\xaeter'.decode('utf8'),'diviser'.decode('utf8')]
axim.imshow(matrix, cmap=cm.jet, interpolation='nearest',origin='lower')
axim.set_xticks(range(2))  
axim.set_xticklabels(xtics,fontsize=15,rotation=25,ha='right',family='monospace')
axim.set_yticks(range(2))
axim.set_yticklabels(ytics,fontsize=15,family='fantasy')#,fontname='AR  
PL ungtiL GB')
plt.show()

Thank you for your help,

Benoit
