【python学习】matplotlib绘制双坐标柱状图及柱线图

双坐标柱状图

import matplotlib.pyplot as plt
x=['time1','time2','time3','time4','time5']
y1=[1,2,3,4,5]
y2=[0.1,0.5,1,2,3]
fig=plt.figure()
ax1 = fig.add_subplot(111)
ax1.bar(x,y1,color='lightgray')
ax2 = ax1.twinx()
ax2.bar(x,y2)

font1 = {'family' : 'Arial',

ax1 = fig.add_subplot(111)
ax1.bar(x,y1,label='y1',color='lightgray')#绘制柱状图
plt.legend(frameon=False,fontsize='large',bbox_to_anchor=(0.5, 1.02), loc=3, borderaxespad=0)
plt.xlabel('time',font1)
plt.ylabel('test',font1)
plt.xticks(rotation=90,fontsize=12)#调整刻度数值显示角度
plt.yticks(fontsize=12)
ax2 = ax1.twinx()
ax2.bar(x,y2,label='y2',color='tab:pink')
plt.legend(frameon=False,fontsize='large',bbox_to_anchor=(0.02, 1.02), loc=3, borderaxespad=0)
plt.xlabel('time',font1)
plt.ylabel('y2',font1)

ax1.bar(x,y1,color='lightgray')
ax2 = ax1.twinx()
