#### 15.4.8.1 Customizing Toolkit Behavior

The specific behavior of the backend toolkit may be modified using the following utility functions. Note: Not all functions apply to every graphics toolkit.

: [prog, args] = gnuplot_binary () ¶
: [old_prog, old_args] = gnuplot_binary (new_prog) ¶
: [old_prog, old_args] = gnuplot_binary (new_prog, arg1, …) ¶

  Query or set the name of the program invoked by the plot command when the graphics toolkit is set to `"gnuplot"`.

  Additional arguments to pass to the external plotting program may also be given. The default value is `"gnuplot"` with no additional arguments. See Installing Octave.

  See also: graphics_toolkit.

In addition, the gnuplot program usually provides a number of different interfaces, known as terminals. Octave normally chooses a default terminal, but you can override this with the environment variable `GNUTERM`. This variable may be set in the shell before starting Octave or from within Octave before plotting for the first time. For example:

    setenv ("GNUTERM", "wxt")
    graphics_toolkit ("gnuplot")
    plot (1:10)
