Created attachment 178274 [details] Spreadsheet with chartsheet Excel, and perhaps ODC, has the concept of a chartsheet, a sperate worksheet that can only contain a chart. This isn't supported by Libreoffice - the chartsheet shows as an empty worksheet. It would be great if it did. The attached workbook is an example of the "problem". It was created using openpyxl (under Linux) and displays in Excel but not Libreoffice. Regards Angus
