问题描述
这是我计划用于创建BAR图表的代码。忽略下一行。我正在编写此代码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,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，我收到此错误：
Traceback (most recent call last):
