为什么一定要掌握自学能力笔记2

人类发展指数

hdi-china-1870-2015.txt文件和humandev.py 存放在 https://github.com/qinfeng8848/self-study

python3环境安装 https://www.liaoxuefeng.com/wiki/0014316089557264a6b348958f449949df42a6d3a2e542c000/0014316090478912dab2a3a9e8f4ed49d28854b292f85bb000

matplotlib 安装 https://morvanzhou.github.io/tutorials/data-manipulation/plt/1-2-install/

以下是我把代码跑起来的记录

将代码保存在self-study文件夹取名humandev.py

import matplotlib.pyplot as plt
import numpy as np
plt.figure(figsize=(10,5))

lebdata = np.genfromtxt('life-expectancy-china-1960-2016.txt',
                     delimiter=',',
                     names=['x', 'y'])

hdidata = np.genfromtxt('hdi-china-1870-2015.txt',
                     delimiter=',',
                     names=['x', 'y'])

plt.plot(hdidata['x'], hdidata['y'])
plt.tick_params(axis='x', rotation=70)
plt.title('China: 1870 - 2015')
plt.savefig('human-development-index.png', transparent=True)plt.legend(['Human Development Index'])
plt.plot(lebdata['x'], lebdata['y']*0.005)
plt.plot(secondary_y=True)
plt.savefig('human-development-index-china-1870-2015.png', transparent=True)
plt.show()
