1. 查找當前系統的已用字體:

fc-list :lang=zh;

2. 添加如下代碼:

from matplotlib import rcParams
from matplotlib.font_manager import FontProperties
import matplotlib.pyplot as plt
# 解決負號'-'顯示爲方塊的問題
rcParams['axes.unicode_minus']=False
myfont = FontProperties(fname='/System/Library/Fonts/PingFang.ttc',
 size=15)
plt.title('乘客等級分佈', fontproperties=myfont)
