In Grapher 16, the Grapher file format was changed so that it can open files saved in newer versions of Grapher. For example, Grapher 16 can open a GRF saved in Grapher 17 Preview. Simply save to the default GPJ or GRF format from Grapher 16 and newer.
To open your files in Grapher 15 or older, you can save your GRF or GPJs to the previous version formats. To save a file to an older version:
- Click the File | Save As command.
- Next to the Save as type, click the existing option and select the desired format from the list.
Select the desired format from the Save as type list.
- After clicking Save, the file is saved in the format selected.
Note that new features may not translate to older versions. So, some items may be displayed differently when saving back to an older version.
