我需要拿出一张不同列表的条形图
import math
import numpy as np
import matplotlib.pyplot as plt
month=["dec-09","jan","feb"]
n=len(month)
kitchen=[57.801,53.887,49.268]
laundry=[53.490,56.568,53.590]
air=[383.909,395.913,411.714]
other=[519.883,483.293,409.956]
ind=np.arange(n)
width=0.35
p1=plt.bar(ind,kitchen,width,color="cyan")
p2=plt.bar(ind,laundry,width,color="red",bottom=kitchen)
p3=plt.bar(ind,air,width,color="green",bottom=kitchen+laundry)
p4=plt.bar(ind,other,width,color="blue",bottom=kitchen+laundry+air)
plt.ylabel("KWH")
plt.title("winter")
plt.xticks(ind+width/2,("dec-09","jan","feb"))
plt.show()
它只是一个简单的代码,我想把它们叠加但我遇到了一个错误,我不知道该怎么办
p3=plt.bar(ind,air,width,color="green",bottom=kitchen+laundry)
