import pandas as pd
import matplotlib.pyplot as plt
import numpy as np
def dbargraph():
    df=pd.read_csv('C:\\Users\Bhuwan Bhatt\Desktop\IP PROJECT\olymp_data.csv',encoding='cp1252')
    df.sort_values(by='TotalMedal',ascending=False,inplace=True)
    df1=df.head(n=10)
    x=np.arange(len(df1))
    Countries=df1['Country']
    Summermedal=df1['SummerTotal']
    Wintermedal=df1['WinterTotal']
    plt.bar(x-0.2,Summermedal,label='Total Medals won by Top 10 Countries IN SUMMER',width=0.4,color='orangered')

您是否尝试通过 set_yticks() 手动设置它？我不确定您是否不需要设置轴，即

轴 = plt.axes()

然后指定 x 和 y 刻度的范围。这可能会有所帮助
