将百分比添加到JointGrid中的直方图

import seaborn as sns
import matplotlib.pyplot as plt

grid = sns.JointGrid(x=data['x'], y=data['y'])

grid.plot_joint(sns.scatterplot, color='b')
grid.plot_marginals(sns.histplot, kde=True, color='b')

def add_percentage(ax, data, x, y):
    total = len(data)
    for p in ax.patches:
        percentage = '{:.1f}%'.format(100 * p.get_height() / total)
        x_pos = p.get_x() + p.get_width() / 2
        y_pos = p.get_height()
        ax.annotate(percentage, (x_pos, y_pos), ha='center', va='bottom')

add_percentage(grid.ax_marg_x, data, 'x', 'y')
add_percentage(grid.ax_marg_y, data, 'y', 'x')

plt.show()
