一.多个图不在一个板里画
from matplotlib import pyplot as plt
x1=['1','2','3']
y1=[4,5,6]
x2=[4,5,7]
y2=[7,8,9]
x3=[12,15,17]
y3=[70,80,90]
fig1=plt.figure()
fig2=plt.figure()
fig3=plt.figure()
ax1=fig1.add_subplot(111)
ax2=fig2.add_subplot(111)
ax3=fig3.add_subplot(111)
ax1.bar(x=x1,height=y1,width=0.5)
ax2.plot(x2,y2)
ax3.plot(x3,y3)
plt.show()
