五. 堆图

import matplotlib.pyplot as plt

days = [1,2,3,4,5]

sleeping = [7,8,6,11,7]
eating =   [3,3,4,2,3]
working =  [7,8,7,3,2]
playing =  [7,5,7,8,12]

#stack chart 没有图例，所以用这种方式加上图例
plt.plot([],[],color=‘m‘, label=‘sleeping‘, linewidth=5)
plt.plot([],[],color=‘c‘, label=‘eating‘, linewidth = 5)
plt.plot([],[],color=‘r‘, label=‘working‘,linewidth = 5)
plt.plot([],[],color=‘k‘, label=‘playing‘,linewidth = 5)


plt.stackplot(days, sleeping, eating, working, playing, colors=[‘m‘,‘c‘,‘r‘,‘k‘])
plt.xlabel(‘x‘)
plt.ylabel(‘y‘)
plt.title(‘stack chart\n‘)
plt.legend()
plt.show()
