### 3.25 set-show

The ‘set‘ command can be used to set _lots_ of options. No screen is drawn, however, until a ‘plot‘, ‘splot‘, or replot command is given.

The ‘show‘ command shows their settings; ‘show all‘ shows all the settings.

Options changed using ‘set‘ can be returned to the default state by giving the corresponding unset command. See also the reset command, which returns all settable parameters to default values.

If a variable contains time/date data, ‘show‘ will display it according to the format currently defined by timefmt, even if that was not in effect when the variable was initially defined.

The ‘set‘ and unset commands may optionally contain an iteration clause. See iteration.
