Chart being renamed after saving
Dear all,
I would like to report a possible bug with openpyxl.
I'm opening an existing xlsm file in append mode via the pandas.ExcelWriter. The excel file contains several charts that have been named. When the workbook is saved, the charts are there, but they have been renamed to their original "Chart 1", "Chart 2"... names.
Can you have a look at that?
Cheers, toto
