解决matplotlib中文乱码问题的五种有效方法

import matplotlib.pyplot as plt

# 查找系统默认字体路径
print(plt.rcParams["font.family"])

# 修改系统默认字体
plt.rcParams["font.family"] = "Arial Unicode MS"

# 正常显示中文
plt.title("中文标题")
plt.show()

import matplotlib.pyplot as plt

# 手动指定字体
font = {"family": "Arial Unicode MS"}

plt.title("中文标题", fontdict=font)
plt.show()

import matplotlib.pyplot as plt
import matplotlib.font_manager as fm

# 获取字体列表
font_list = fm.findSystemFonts()

# 选择一个适合的字体
font_path = font_list[0]
font_prop = fm.FontProperties(fname=font_path)

plt.title("中文标题", fontproperties=font_prop)
plt.show()

import matplotlib.pyplot as plt

# 创建字体配置文件matplotlibrc
with open("matplotlibrc", "w") as f:
    f.write("font.family: Arial Unicode MS")

# 使用字体配置文件
plt.rcParams["font.family"] = "Arial Unicode MS"

plt.title("中文标题")
plt.show()

import matplotlib.pyplot as plt
from fontTools.ttLib import TTFont

# 查找字体支持的字符集和语言
font_path = "Arial Unicode MS.ttf"
font = TTFont(font_path)
font_names = font.getNames()
charsets = set()
languages = set()

for name in font_names:
    if name.isUnicode():
        charsets.add(name.string.decode("utf-16"))
    if name.isWWSFamilyName():
        languages.add(name.string.decode())

print("字符集：", charsets)
print("语言：", languages)

plt.title("中文标题")
plt.show()
