Missing graph after combining xls files

[Kishore01]

Hello,
I have multiple xls files , some with graphs.I am combining these files into worksheets of a single xlsx workbook.
After combining, the final output xls workbook does not have the graphs.Below is the code Iam using to combine the xls file:

1 2 3 4 5 6 7 8 9 10 11 12 13

import pandas as pd import os import csv import glob    path = './' all_files = glob.glob(os.path.join(path, "*.xlsx")) writer = pd.ExcelWriter('out.xlsx', engine='xlsxwriter')   for f in all_files:     df = pd.read_excel(f)     df.to_excel(writer, sheet_name=os.path.splitext(os.path.basename(f))[0], index=False)   writer.save()

Is there anything missing in the above code?
