当我运行代码查看箱形图时，我注意到图的x轴中没有文件名，而是显示1，2，3，4，5，6 .....
这是我现在正在研究的代码

import os
import numpy as np
import matplotlib.pyplot as plt
from PIL import Image

folder_path = "path to image folder"

# Get a list of the TIFF image in the folder
tiff_files = [f for f in os.listdir(folder_path) if f.endswith('.tiff')]

# Loop through the images in the folder
grey_values = []
for img_file in tiff_files:
    img = Image.open(os.path.join(folder_path, img_file))
    grey_values.append(np.asarray(img).ravel())

# Plot the grey values as a box graph
plt.boxplot(grey_values)
plt.title('Grey Values of TIFF Images')
plt.xlabel('Image')
plt.ylabel('Grey Value')
plt.show()

我试过添加“Label=tiff_files”，但它会抛出错误，并且不知如何将文件名替换为正常编号。
