29 ## The function state input may be either @qcode{"on"} or @qcode{"off"}.
30 ## If it is omitted, the current grid state is toggled.
31 ##
32 ## When the first argument is @qcode{"minor"} all subsequent commands
33 ## modify the minor grid rather than the major grid.
34 ##
35 ## If the first argument @var{hax} is an axes handle, then operate on
36 ## this axis rather than the current axes returned by @code{gca}.
37 ##
38 ## To control the grid lines for an individual axis use the @code{set}
39 ## function. For example:
40 ##
41 ## @example
42 ## set (gca, "ygrid", "on");
43 ## @end example
