If you did a local import, say from an Excel spreadsheet, then you would need to import the spreadsheet again to pick up the new rows. Then, refresh in Visual Analytics should work to pick up the new data (if it is not automatically picked up).
If you don't have permission to re-import the spreadsheets, then either the person who originally imported will need to repeat the action, or an admin can give you permission to do it. To load or import you need the following:
- ReadMetadata on the LASR server
- ReadMetadata, Read, WriteMetadata, Administer on the library
- ReadMetadata, Read, WriteMemberMetadata, Write on the folder
See Permissions: LASR Tables and Servers in the Visual Analytics Admin Guide:
