Python ValueError形状不匹配：无法将对象广播到单个形状

这是我计划用来创建条形图的代码。忽略下一行。我写这篇文章只是为了平衡代码和细节

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
def bar1():
    df=pd.read_csv('C:\\Users\Bhuwan Bhatt\Desktop\IP PROJECT\Book1.csv',encoding= 'unicode_escape')
    x=np.arange(11)
    Countries=df['Country']
    STotalMed=df['SummerTotal']
    WTotalMed=df['WinterTotal']
    plt.bar(x-0.25,STotalMed,width=.2, label='Total Medals by Countries in Summer',color='g')
    plt.bar(x+0.25,WTotalMed,width=.2, label='Total Medals by Countries in Winter',color='r')
    plt.xticks(np.arange(11),Countries,rotation=30)
    plt.title('Olympics Data Analysis of Top 10 Countries',color='red',fontsize=10)
    plt.xlabel('Countries')
    plt.ylabel('Total Medals')
    plt.grid()
    plt.legend()
    plt.show()
bar1()

由于某种原因，我出现此错误：

信息------->夏季部分：每个国家参加夏季活动的次数 冬季时间部分：每个国家参加冬季活动的次数TA

仅需更改

x=np.arange(11)

to 

x = np.arange(len(df))

及

---

很可能您的绘图向量的长度不同。请尝试输入x=np.arange（len（df））@Psidom输入x=np.arange（len（df））''值错误后显示新错误：FixedLocator位置（11）的数量（通常来自设置刻度的调用）与TickLabel（149）的数量不匹配。“

plt.xticks（np.arange（len（df）），国家/地区，轮换=30）

？@Psidom Thnks兄弟，它成功了。还有一件事我想问。csv大约有250行，所以我如何才能得到这段代码中的前10个国家的条形图（根据TotalCarners）。按TotalCarners的降序排序

df

…比如…

df.Sort_值（按='TotalCarners'，升序=False，原地=True）

然后将

df

过滤为

df1=df.head（10）

…并在

df1

x=np.arange(11)

to 

x = np.arange(len(df))

plt.xticks(np.arange(11),Countries,rotation=30) 

to

plt.xticks(x,Countries,rotation=30)
