boxplot 绘制箱线图，添加数据点

先看效果图

import matplotlib.pyplot as plt 
#! 解决不显示的问题：中文设置为宋体格式
plt.rcParams['font.family'] = ["Times New Roman", 'SimSun']

def plot_boxplot(data_list, out_file, x_custom_labels):
    # 画图
    fig, ax = plt.subplots(figsize=(90, 60))
    ax.boxplot(data_list,
                notch=True,
                vert=True, 
                patch_artist=True)
    # 添加数据点
    for i, d in enumerate(data_list):
        y = d
        x = np.random.normal(i+1, 0.04, len(y))
        ax.plot(x, y, 'r.', alpha=0.5, markersize=10)
        # 添加数值
        # median = np.median(d)
        # plt.text(i+1.2, median, median, fontweight='bold', ha='center', va='bottom', size=4, rotation=60)
    #刻度值字体大小设置（x轴和y轴同时设置）
    plt.tick_params(labelsize=20)
    # 自定义 X 轴标签
    ax.set_xticklabels(x_custom_labels, rotation=45, ha='right', fontweight='bold')
    plt.xticks(fontweight='bold' )
    # 添加网格线
    ax.yaxis.grid(True, linestyle='--', which='major', color='grey', alpha=.45)
    ax.xaxis.grid(True, linestyle='--', which='major', color='grey', alpha=.45)
    plt.title(f'Boxplot Plots for {down_lvl}G', fontsize=80)
    plt.xlabel('Site', fontsize=50)
    plt.ylabel('Depth', fontsize=50)
    plt.legend()
    # # 调整子图间距
    plt.tight_layout()
    # 显示图形
    plt.show()
    plt.savefig(out_file)
