When opening a GRF, Grapher looks in the following locations in the following order for the data sheet associated with the graph:
- The relative or absolute Worksheet path, if one is specified in File | Options | General (Tools | Options | General in older versions).
- The path that was stored to the worksheet in the GRF file.
- In the same directory as the GRF file.
If the worksheet is not found, you'll be prompted for it. If you are using Grapher 12 or newer, you can select the new file path and for each subsequent data file Grapher will search in that new directory. Alternatively, if all the worksheets in your graph use the same data file, you can use the Graph Tools | Worksheet | Change command to update the file path for all data files associated with all the plots. If your data sheets are in different locations, you'll need to update them one by one.
If you are using an older version of Grapher and a common folder is used for the data files, you may want to specify a Worksheet path for your data files or move the GRF file to this location.
