如果想将柱状图按照序排列，可以先对数据进行排序，再绘制柱状图。以下是修改后的代码：

import numpy as np
import csv
import pandas as pd
import numpy as npjk    
import matplotlib.pyplot as plt
from wordcloud import WordCloud
plt.rcParams['font.sans-serif']=['SimHei']#解决图标中汉字显示问题
plt.rcParams['axes.unicode_minus']=False#解决图标中汉字显示问题
from urllib.request import urlopen,Request
from bs4 import BeautifulSoup

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.45 Safari/537.36'}
url = 'https://search.jd.com/Search?keyword=%E8%93%9D%E7%89%99%E9%BC%A0%E6%A0%87&enc=utf-8&wq=%E8%93%9D%E7%89%99%E9%BC%A0%E6%A0%87&pvid=405a663911e84dd3822389ef5b97c147'
response = Request(url,headers=headers)
res = urlopen(response)
data = res.read().decode('utf-8')
soup = BeautifulSoup(data,'html.parser')
ddd=soup.find('ul',class_="gl-warp clearfix")
bbb=ddd.select('li>.gl-i-wrap>.p-price>strong>i')#价格
ccc=ddd.select('li>.gl-i-wrap>.p-shop>span>a')#店名

get_rmb_date = []
for i in bbb:
    get_rmb_date.append(float(i.text))

get_shop_date = []
for i in ccc:
    get_shop_date.append(i.text)

# 对数据进行排序
data = sorted(zip(get_shop_date, get_rmb_date), key=lambda x: x[1], reverse=True)
get_shop_date, get_rmb_date = zip(*data)

print(data)

f = open('D:/mypython/mycode/2021058226.csv','w',encoding='utf-8')
csv_write = csv.writer(f)

csv_write.writerow(['商品店家','商品价格'])

for i in data:
    csv_write.writerow(i)

f.close()

csv_file ='D:/mypython/mycode/2021058226.csv'
csv_data=pd.read_csv(csv_file,low_memory=False)
csv_df=pd.DataFrame(csv_data)

dfl=csv_df.head(n=10)
print(dfl)

plt.figure(figsize = (10,6))
x = np.arange(10)
y = np.array(dfl['商品店家'])
xticks = list(dfl['商品价格'])
print(x,y,xticks)

p = [0,1,2,3,4,5,6,7,8,9]

plt.xticks(p, y, rotation=20)
plt.bar(p, xticks, color='red')
plt.show()

这样，柱状图就会按照商品价格的高低进行排列。
