yes matplotlib There are no Chinese fonts in the library .

that , Let's just install it .

1、 adopt pip install 【anaconda】

pip3 install anaconda

2、 Add settings

from matplotlib import pyplot as plt

plt.rcParams['font.sans-serif'] = ['SimHei']  #  Used to display Chinese labels normally 
plt.rcParams['axes.unicode_minus'] = False  #  Used to display negative sign normally 

Demo Example ：

from matplotlib import pyplot as plt
import random

plt.rcParams['font.sans-serif'] = ['SimHei']  #  Used to display Chinese labels normally 
plt.rcParams['axes.unicode_minus'] = False  #  Used to display negative sign normally 
#  Abnormal temperature change value 
# 0. Get ready x, y Coordinate data 
x = range(100)
y_jiangsu = [random.randint(-50, 60) for i in x]

# 1. Create a canvas 
plt.figure(figsize=(20, 8), dpi=80)
# 2. Draw line chart 
plt.plot(x, y_jiangsu)
plt.title(" Abnormal temperature change table ")
plt.xlabel(" temperature ℃")
plt.ylabel(" Record times ")
# 3. Display images 
plt.show()
