[Python] matplotlib.pyplot 을 이용해서 line chart 만들기

LINE CHART

 

import matplotlib.pyplot as plt


plt.figure(figsize=(10, 5))

lang_list = ['2018', '2019', '2020', '2021', '2022']
plt.plot(lang_list, [10, 12, 15, 16, 20], marker='o')
plt.plot(lang_list, [14, 16, 15, 18, 17], marker='o')
plt.plot(lang_list, [20, 18, 15, 14, 12], marker='o')
plt.legend(['Python', 'Java', 'Obj-C'])

plt.grid(True)
plt.show()

plt.grid(False) 이면

Title, x, y Label

plt.xlabel('years')
plt.ylabel('Languages')
plt.title('Language usage rate.')

 

color, marker, linestyle

plt.plot(lang_list, [10, 12, 15, 16, 20], marker='o', color='#c1abff', linestyle='--')
plt.plot(lang_list, [14, 16, 15, 18, 17], marker='s', color='#d8e1c5', linestyle=':')
plt.plot(lang_list, [20, 18, 15, 14, 12], marker='*', color='#80afe5')

 

이미지 저장

plt.savefig('my_line_image.png')
