在ubuntu 下利用matplotlib 绘图的时候,图像上中文显示乱码
- 下载中文字体simhei.ttf, 网址为http://fontzone.net/download/simhei
- 搜索 matplotlib 字体的安装位置
locate -b '\mpl-data'
会得到 这个路径/usr/share/matplotlib/mpl-data下面有fonts/ttf这个目录,进入这个目录,把刚才下载的simhei.ttf 字体复制到这个目录***意权限和归属是否与其它字体一致,我的是归于root用户的,所以用root 用户复制过来。
3. 删除当前用户matplotlib 的缓冲文件(如果没有直接进入第四步)
cd ~/.cache/matplotlib
rm -rf *.*
# test.py
import itchat, time
import matplotlib.pyplot as plot
rName = 'Group_name'
def chatProportion(rName):
need_user = []
itchat.auto_login(True)
male = female = other = 0
# rName = rName
roomSum = 0
chatRooms = itchat.search_chatrooms(name=rName)
print(chatRooms)
if chatRooms is None:
print("no this:" + rName)
else:
chatRoom = itchat.update_chatroom(chatRooms[0]['UserName'], detailedMember=True)
index = 0
mem_list = chatRoom['MemberList']
roomSum = len(mem_list)
for friend in mem_list:
dis = friend['DisplayName']
nick = friend['NickName']
sex = friend['Sex']
city = friend['City']
if sex == 1:
male += 1
elif sex == 2:
female += 1
if city in ['东城',
'西城',
'海淀',
'朝阳',
'丰台',
'门头沟',
'石景山',
'房山',
'通州',
'顺义',
'昌平',
'大兴',
'怀柔',
'平谷',
'延庆',
'密云',
'Dongcheng',
'Xicheng',
'Haidian',
'Zhaoyang',
'Fengtai',
'Mentougou',
'Shijingshan',
'Fangshan',
'Tongzhou',
'Shunyi',
'Changping',
'Daxing',
'Huairou',
'Pinggu',
'Yanqing',
'Miyun']:
need_user.append((index, dis, nick, sex, city))
print(index, dis, nick, sex, city)
else:
other += 1
index += 1
labels = ['男:' + str(male), '女' + str(female), '其他' + str(other)]
sizes = [male, female, other]
colors = ['green', 'red', 'gray']
# 几个分量向外偏移
explode = (0.1, 0.1, 0)
plot.pie(sizes, explode, labels, colors, '%2.0f%%')
plot.axis('equal')
plot.legend(loc='upper left', bbox_to_anchor=(-0.1, 1))
plot.rcParams[u'font.sans-serif'] = ['simhei']
plot.rcParams['axes.unicode_minus'] = False
plot.title("群名:" + str(rName) + "[总人数:" + str(roomSum) + "]\n" + str("(男女比例分析-流年master出品)"))
plot.grid()
plot.show()
print(need_user)
4.代码中调整字体
其中#coding:utf-8 说明文件编码格式
mpl.rcParams[u’font.sans-serif’] = [‘simhei’] 用simhei 字体显示中文
mpl.rcParams[‘axes.unicode_minus’] = False 这个用来正常显示负号
plt.title(u’标题’)这里的u 最好不要少
