3.7.4.2 environment variables

The environment variables must be defined before ‘gnuplot‘ is executed; how to do so depends on your operating system.

      FIT_LOG

changes the name (and/or path) of the file to which the fit log will be written from the default of "fit.log" in the working directory. The default value can be overwritten using the command ‘set fit logfile‘.

      FIT_SCRIPT

specifies a command that may be executed after an user interrupt. The default is replot, but a ‘plot‘ or ‘load‘ command may be useful to display a plot customized to highlight the progress of the fit.
