The current version of Grapher opens graphs created in Grapher 2 and above. Grapher DOS and Grapher 1 files are no longer supported. To convert these old files so you can open them in newer versions of Grapher, submit a support request containing the GRF files and any data files they use, and we will send you back the converted files.
Alternatively, if you have an older version of Grapher between Grapher 3 and Grapher 8, you can open the old files in that version and resave them. If you have many files, you can use this script instead of manually opening and resaving the files:
- Download the attached convert old GRF to G7.BAS script file.
- Open the script in Grapher's Script Manager in Grapher version 3-8.
- Change the line: Directory = "D:\temp\Grapher\" to the desired directory that contains your GRF files.
- Click the Start/Resume (green arrow) button. New GRF files are created in the same directory with _G7 appended to the file names. These files can be opened in the current version of Grapher.
Note: if you are having trouble getting the script to run in the older version of Grapher, close Grapher then open it again by right clicking over the shortcut or EXE and clicking Run as administrator. This will switch the default version of Grapher to the old version. When complete, run the latest version as an admin to reset the default to the latest version.
