I use VBA to create charts in Excel 2003, but find that sometimes the
Charts switch 'Series in Rows' (intended) to 'Series in Columns' (not
intended), even if I have specified 'Series in Rows'. This happens
intermittently, and I am not sure what I am doing wrong. I do save
the workbook as Microsoft Excel 97 so that a user with Excel 2000 or
Excel 2003 can use the workbook.

Thank you for any suggestions.
