import pandas as pd
import matplotlib.pyplot as plt

students = pd.read_excel('D:/output.xlsx', index_col='idx')

students.sort_values(by='M2019', inplace=True, ascending=True)

print(students)
# 设置柱状图
# 使用pandas绘图
students.plot.bar(x='Name', y=['M2018','M2019'], color=['orange','red'], title='Internation Students By Field')

plt.title('This is Internation Students by Field',fontsize=16, fontweight='bold')

plt.xlabel('Student Name', fontweight='bold')

ax.set_xticklabels(students.Name, rotation='45', ha='right')

af = plt.gcf()
af.subplots_adjust(left=0.2, bottom=0.42)

#设置为紧凑型布局
#plt.tight_layout()
