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