Reload Data - Worksheet
The worksheet Data Tools | Reload Data command reloads the worksheet contents from a saved version of the file. This is useful when you make changes to the data file in another program (e.g. Excel) and want the changes to appear in Grapher. Save the contents of the file in the other program before selecting the Reload Data command. When the data are reloaded, any previous changes made to the original data are overwritten. If you import the data and plan to make changes, do not use Data Tools | Reload Data, as there is no Undo command for it.
Imported databases appear in a new worksheet window. Once the worksheet is saved, the link to the database is removed.
If you wish to reload data in the plot window, click the File | Reload Data or Graph Tools | Worksheet | Reload command.
