如何设置条形标签的格式以删除科学记数法?

highest_enrollment = course_data.groupby(
    "course_organization")["course_students_enrolled"].sum().nlargest(10)

ax = sns.barplot(x=highest_enrollment.index, 
                 y=highest_enrollment.values, 
                 ci=None, 
                 palette="ch: s=.5, r=-.5")

ax.ticklabel_format(style='plain', axis="y")

plt.xticks(rotation=90)

ax.bar_label(ax.containers[0])

plt.show()

正如BigBen在评论中建议的那样,您可以将fmt参数传递给**matplotlib.axes.Axes.bar_label**;你可以用%d来表示整数:

import matplotlib.pyplot as plt
import seaborn as sns
import pandas as pd

highest_enrollment = pd.DataFrame({'class': ['A', 'B', 'C'],
                   'values': [30000000, 20000000, 10000000]})

ax = sns.barplot(data = highest_enrollment, x = 'class', y = 'values', palette="ch: s=.5, r=-.5")

ax.ticklabel_format(style='plain', axis="y")

plt.xticks(rotation=90)

ax.bar_label(ax.containers[0], fmt = '%d')

plt.show()
