+Please see L<Spreadsheet::WriteExcel/> for more information about the offset and scaling options as well as any other restrictions that might be in place. This node does B<NOT> perform any sort of validation upon your parameters. You are assumed to know what you are doing.
+
+Note that the offset and scaling values are "X,Y". You I<must> provide both values, even if the Y value is 0. If you provide a 0 value for either scaling option, L<Spreadsheet::WriteExcel/> will default that to 1.
