You can create a new map window with the File | New | Plot command or the button on the Quick Access Toolbar. You can create maps in a plot window and use the worksheet to manage data. Existing maps or worksheets are not altered by this command because the new window is independent of all other document windows. A new map may be created or an existing map may be loaded into a new map window. The opened window is empty when created. A worksheet window may also be created with the File | New | Worksheet command.
