Display chinese labels

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 comment 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 SungtiL GB')
plt.show()

Thank you for your help,

Why are you setting the font family to “monospace” and “fantasy” here?
You need to set the font to something that will have the Chinese
characters, for example, by uncommenting the lines that set sans-serif
to “SimHei” above. (That should work, but I don’t have a Chinese font
on my system to test with.)

maybe change the line
"""axim.set_yticklabels(ytics,fontsize=15,family='fantasy')""" to
"""axim.set_yticklabels(ytics,fontsize=15, fontname= "simsun (founder
extended)")"""
(or replace fontname with "simhei" or "microsoft yahei") is enough.

or, put these two lines:
mpl.rcParams['font.sans-serif'] = ['SimHei']
mpl.rcParams['axes.unicode_minus'] = False

there is a Chinese blog (not mine) maybe worth reading:

Thank you for your help,

but it does not seem to work.

I have downloaded simhei fonts and added it in my directory /usr/shared/fonts/truetype but even by using
"""fontname="simhei" """,
or:
"""mpl.rcParams['font.sans-serif'] = ['SimHei']
mpl.rcParams['axes.unicode_minus'] = False """

i still display empty boxes instead of chinese characters.

It is worth noting that these chinese characters print well on the console if i add the line:
"""for ytic in ytics:
     print ytic"""

Unfortunately, apart from copying lines of code, i cannot do much with the blog you mention, as i don't understand what is written in it.

@Mike: "monospace" family is one that enables me to display accents of french words, for the xticks. "fantasy" family was the last family i tried for the chinese labels, but to no success.

So, has anyone managed to do it? Is there something i am missing?,

oh, only test it on Windows yet. both "sim hei"and "microsoft yahei"
are fontname on Windows Platform.
maybe just copy "Sim Hei" to font directory is not enough? no clue here.

I just test the script on Linux (Ubuntu 8.04, Python 2.5, matplotlib
0.98.4) with the follow steps:
1, find the configure directory of matplotlib
import matplotlib as mpl
mpl.get_configdir()

return "~/.matplotlib"
2, in the configure directory, there is a file "fontList.cache"
I find this
(dp294
...
S'WenQuanYi Zen Hei'
...
S'/usr/share/fonts/truetype/wqy/wqy-zenhei.ttf'
...

I just know WenQuanYi is a "Chinese font"
http://packages.ubuntu.com/hardy/ttf-wqy-zenhei
3, replace "Sim Hei" in your original script with "WenQuanYi Zen Hei",
now it can display Chinese.
both methods still work(embed fontname argument, or set
mpl.rcParams['font.sans-serif'])

maybe you can find a font that support Chinese character on your
platform with these steps and try again?

Hi,

When looking in my fontFile.cache, i did not find any of '/usr/share/fonts/truetype/wqy/wqy-zenhei.ttf', '/usr/share/fonts/truetype/wqy/wqy-microhei.ttf' or simhei. this is why i could not display the characters.

I deleted the cache and re-lounched my script, so that mpl had to look for the fonts and update the cache. It added the simhei fonts to the list. I can now display chinese characters with the simhei font.

I ran into 2 more issues:
- Simhei "has no glyph names", which prevents me from exporting into pdf
- I do not manage to make mpl take into account microhei and zenhei, whereas i have them in '/usr/share/fonts/truetype/wqy/wqy-microhei.ttc'. I changed their name to '/usr/share/fonts/truetype/wqy/wqy-microhei.ttf', and now mpl finds them. However they fail to display chinese characters

So, thank you for your help, i managed to display chinese characters but there are still some issues. Do you have any idea?

Actually, i must apologize

By calling fonts by their real name eg: "WenQuanYi Zen Hei" (instead of wqy-microhei, their file name), i can display them. So no worries for issue 2. However, I do not manage to export the png to pdf or eps due to the following error:

"TrueType font is missing table"

Is that due to my changing the font name from *.ttc to *.ttf?

Hi,

When looking in my fontFile.cache, i did not find any of
'/usr/share/fonts/truetype/wqy/wqy-zenhei.ttf',
'/usr/share/fonts/truetype/wqy/wqy-microhei.ttf' or simhei. this is why
i could not display the characters.

I deleted the cache and re-lounched my script, so that mpl had to look
for the fonts and update the cache. It added the simhei fonts to the
list. I can now display chinese characters with the simhei font.

I ran into 2 more issues:
- Simhei "has no glyph names", which prevents me from exporting into pdf
- I do not manage to make mpl take into account microhei and zenhei,
whereas i have them in
'/usr/share/fonts/truetype/wqy/wqy-microhei.ttc'. I changed their name
to '/usr/share/fonts/truetype/wqy/wqy-microhei.ttf', and now mpl finds
them. However they fail to display chinese characters

So, thank you for your help, i managed to display chinese characters
but there are still some issues. Do you have any idea?

oh, only test it on Windows yet. both "sim hei"and "microsoft yahei"
are fontname on Windows Platform.
maybe just copy "Sim Hei" to font directory is not enough? no clue here.

I just test the script on Linux (Ubuntu 8.04, Python 2.5, matplotlib
0.98.4) with the follow steps:
1, find the configure directory of matplotlib
import matplotlib as mpl
mpl.get_configdir()

return "~/.matplotlib"
2, in the configure directory, there is a file "fontList.cache"
I find this
(dp294
...
S'WenQuanYi Zen Hei'
...
S'/usr/share/fonts/truetype/wqy/wqy-zenhei.ttf'
...

I just know WenQuanYi is a "Chinese font"
http://packages.ubuntu.com/hardy/ttf-wqy-zenhei
3, replace "Sim Hei" in your original script with "WenQuanYi Zen Hei",
now it can display Chinese.
both methods still work(embed fontname argument, or set
mpl.rcParams['font.sans-serif'])

maybe you can find a font that support Chinese character on your
platform with these steps and try again?

I have downloaded simhei fonts and added it in my directory

"""mpl.rcParams['font.sans-serif'] = ['SimHei']
mpl.rcParams['axes.unicode_minus'] = False """

i still display empty boxes instead of chinese characters.

It is worth noting that these chinese characters print well on the console
if i add the line:
"""for ytic in ytics:

Unfortunately, apart from copying lines of code, i cannot do much with the
blog you mention, as i don't understand what is written in it.

@Mike: "monospace" family is one that enables me to display accents of
french words, for the xticks. "fantasy" family was the last family i tried
for the chinese labels, but to no success.

So, has anyone managed to do it? Is there something i am missing?,

so, maybe just rename *.ttc to *.ttf is not enough.

just download the ttf version from

I don't know font enough, so I didn't test the first method. I only
test the last method.
after download the font into my Window machine. it can display Chinese

doesn't work, even without a error log").
(my Linux machine(Ubuntu Hardy 8.04) can display Chinese and save

Thank you very much it all works fine now,

I downloaded and installed the font in http://archive.ubuntu.com/ubuntu/pool/main/t/ttf-wqy-zenhei/ttf-wqy-zenhei_0.5.23.orig.tar.gz, as you advised. Then i deleted the fontList.cache de matplotlib to force its updating, and ran the script with """ fontname="WenQuanYi Zen Hei" """

I can now display the characters and save the plots as pdf.

Thanks a lot for you wise help, i learned a lot.

Thank you very much it all works fine now,

I downloaded and installed the font in
http://archive.ubuntu.com/ubuntu/pool/main/t/ttf-wqy-zenhei/ttf-wqy-zenhei_0.5.23.orig.tar.gz,
as you advised. Then i deleted the fontList.cache de matplotlib to force its
updating, and ran the script with """ fontname="WenQuanYi Zen Hei" """

I can now display the characters and save the plots as pdf.

Thanks a lot for you wise help, i learned a lot.

Actually, i must apologize

By calling fonts by their real name eg: "WenQuanYi Zen Hei" (instead of
wqy-microhei, their file name), i can display them. So no worries for
issue
2. However, I do not manage to export the png to pdf or eps due to the
following error:

"TrueType font is missing table"

Is that due to my changing the font name from *.ttc to *.ttf?

the "c" in ".ttc" means "Container", wqy-*.ttc includes more than one ttf.
so, maybe just rename *.ttc to *.ttf is not enough.
I guess, You can find some font tools to extract ttf from ttc, or
install another Chinese font provided by your operation system. or
just download the ttf version from
http://packages.ubuntu.com/hardy/ttf-wqy-zenhei (directly:

http://archive.ubuntu.com/ubuntu/pool/main/t/ttf-wqy-zenhei/ttf-wqy-zenhei_0.5.23.orig.tar.gz)
I don't know font enough, so I didn't test the first method. I only
test the last method.
after download the font into my Window machine. it can display Chinese
with "'WenQuanYi Zen Hei'" and save figure to png and pdf.(ps, eps
doesn't work, even without a error log").
(my Linux machine(Ubuntu Hardy 8.04) can display Chinese and save
figure to png, pdf, ps, eps correctly already.)

Hi,

When looking in my fontFile.cache, i did not find any of
'/usr/share/fonts/truetype/wqy/wqy-zenhei.ttf',
'/usr/share/fonts/truetype/wqy/wqy-microhei.ttf' or simhei. this is why
i could not display the characters.

I deleted the cache and re-lounched my script, so that mpl had to look
for the fonts and update the cache. It added the simhei fonts to the
list. I can now display chinese characters with the simhei font.

I ran into 2 more issues:
- Simhei "has no glyph names", which prevents me from exporting into pdf
- I do not manage to make mpl take into account microhei and zenhei,
whereas i have them in
'/usr/share/fonts/truetype/wqy/wqy-microhei.ttc'. I changed their name
to '/usr/share/fonts/truetype/wqy/wqy-microhei.ttf', and now mpl finds
them. However they fail to display chinese characters

So, thank you for your help, i managed to display chinese characters
but there are still some issues. Do you have any idea?

Benoit

oh, only test it on Windows yet. both "sim hei"and "microsoft yahei"
are fontname on Windows Platform.
maybe just copy "Sim Hei" to font directory is not enough? no clue
here.

I just test the script on Linux (Ubuntu 8.04, Python 2.5, matplotlib
0.98.4) with the follow steps:
1, find the configure directory of matplotlib
import matplotlib as mpl
mpl.get_configdir()

return "~/.matplotlib"
2, in the configure directory, there is a file "fontList.cache"
I find this
(dp294
...
S'WenQuanYi Zen Hei'
...
S'/usr/share/fonts/truetype/wqy/wqy-zenhei.ttf'
...

I just know WenQuanYi is a "Chinese font"
http://packages.ubuntu.com/hardy/ttf-wqy-zenhei
3, replace "Sim Hei" in your original script with "WenQuanYi Zen Hei",
now it can display Chinese.
both methods still work(embed fontname argument, or set
mpl.rcParams['font.sans-serif'])

maybe you can find a font that support Chinese character on your
platform with these steps and try again?

but it does not seem to work.

I have downloaded simhei fonts and added it in my directory
/usr/shared/fonts/truetype but even by using
"""fontname="simhei" """,
or:
"""mpl.rcParams['font.sans-serif'] = ['SimHei']
mpl.rcParams['axes.unicode_minus'] = False """

i still display empty boxes instead of chinese characters.

It is worth noting that these chinese characters print well on the
console
if i add the line:
"""for ytic in ytics:
print ytic"""

Unfortunately, apart from copying lines of code, i cannot do much with
the
blog you mention, as i don't understand what is written in it.

@Mike: "monospace" family is one that enables me to display accents of
french words, for the xticks. "fantasy" family was the last family i
tried
for the chinese labels, but to no success.

So, has anyone managed to do it? Is there something i am missing?,

regards,

Benoit.

maybe change the line
"""axim.set_yticklabels(ytics,fontsize=15,family='fantasy')""" to
"""axim.set_yticklabels(ytics,fontsize=15, fontname= "simsun (founder
extended)")"""
(or replace fontname with "simhei" or "microsoft yahei") is enough.

or, put these two lines:
mpl.rcParams['font.sans-serif'] = ['SimHei']
mpl.rcParams['axes.unicode_minus'] = False

there is a Chinese blog (not mine) maybe worth reading:

http://hi.baidu.com/lijiangshui/blog/item/a0aad703cd65ee7e3812bb49.html

hope this help

Hi,

How can one display Mandarin labels in a plot, as yticks_labels for

It looks to me that there is no font in matplotlib that can display

find a
font family that would display Chinese characters.

Here is an example of plot that displays empty boxes instead of

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')]
