28 ## The function state input may be either @qcode{"on"}, @qcode{"xon"},
29 ## @qcode{"yon"} or @qcode{"off"}.
30 ##
31 ## If it is omitted the current state is toggled (@qcode{"xon"} and
32 ## @qcode{"yon"} are treated as @qcode{"on"}).
33 ##
34 ## @qcode{"xon"} limits panning to the x-axis, @qcode{"yon"} to the
35 ## y-axis.
36 ##
37 ## If the first argument @var{hax} is an axes handle, then operate on
38 ## this axis rather than the current axes returned by @code{gca}.
39 ##
40 ## To query the current mode use the @code{get}
41 ## function. For example:
42 ## @example
43 ## mode = get (gca, "pan");
44 ## @end example
45 ## @seealso{rotate3d}
46 ## @end deftypefn
