(Encoding Test) Broken Korean Fonts in matplotlib

matplotlib's font defaults to 'sans-erif', so Korean characters may come out garbled. 

Check the font

import matplotlib
matplotlib.rcParams['font.family']

 

for Win

# 한글 깨짐 개선 
import matplotlib
import matplotlib.font_manager as fm

font_name = fm.FontProperties(fname = 'C:/Windows/Fonts/malgun.ttf').get_name()
matplotlib.rc('font', family = font_name)
matplotlib.rcParams['axes.unicode_minus'] = False

 

for Mac

# 한글 깨짐 개선 
import matplotlib.pyplot as plt
from matplotlib import rc 

rc('font', family='AppleGothic') 			
plt.rcParams['axes.unicode_minus'] = False
