+## @deftypefn {Function File} {} errorbar (@var{args})
+## This function produces two-dimensional plots with errorbars. Many
+## different combinations of arguments are possible. The simplest form is
+##
+## @example
+## errorbar (@var{y}, @var{ey})
+## @end example
+##
+## @noindent
+## where the first argument is taken as the set of @var{y} coordinates
+## and the second argument @var{ey} is taken as the errors of the
+## @var{y} values. @var{x} coordinates are taken to be the indices
+## of the elements, starting with 1.
+##
+## If more than two arguments are given, they are interpreted as
+##
+## @example
+## errorbar (@var{x}, @var{y}, @dots{}, @var{fmt}, @dots{})
+## @end example
+##
+## @noindent
+## where after @var{x} and @var{y} there can be up to four error
+## parameters such as @var{ey}, @var{ex}, @var{ly}, @var{uy}, etc.,
+## depending on the plot type. Any number of argument sets may appear,
+## as long as they are separated with a format string @var{fmt}.
+##
+## If @var{y} is a matrix, @var{x} and error parameters must also be matrices
+## having same dimensions. The columns of @var{y} are plotted versus the
+## corresponding columns of @var{x} and errorbars are drawn from
+## the corresponding columns of error parameters.
+##
+## If @var{fmt} is missing, yerrorbars ("~") plot style is assumed.
+##
+## If the @var{fmt} argument is supplied, it is interpreted as in
+## normal plots. In addition, @var{fmt} may include an errorbar style
+## which must precede the line and marker format. The following plot
+## styles are supported by errorbar:
+##
+## @table @samp
+## @item ~
+## Set yerrorbars plot style (default).
+##
+## @item >
+## Set xerrorbars plot style.
+##
+## @item ~>
+## Set xyerrorbars plot style.
+##
+## @item #
+## Set boxes plot style.
+##
+## @item #~
+## Set boxerrorbars plot style.
+##
+## @item #~>
+## Set boxxyerrorbars plot style.
+## @end table
+##
+## Examples:
+##
+## @example
+## errorbar (@var{x}, @var{y}, @var{ex}, ">")
+## @end example
+##
+## @noindent
+## produces an xerrorbar plot of @var{y} versus @var{x} with @var{x}
+## errorbars drawn from @var{x}-@var{ex} to @var{x}+@var{ex}.
+##
+## @example
+## @group
+## errorbar (@var{x}, @var{y1}, @var{ey}, "~",
+## @var{x}, @var{y2}, @var{ly}, @var{uy})
+## @end group
+## @end example
+##
+## @noindent
+## produces yerrorbar plots with @var{y1} and @var{y2} versus @var{x}.
+## Errorbars for @var{y1} are drawn from @var{y1}-@var{ey} to
+## @var{y1}+@var{ey}, errorbars for @var{y2} from @var{y2}-@var{ly} to
+## @var{y2}+@var{uy}.
+##
+## @example
+## @group
+## errorbar (@var{x}, @var{y}, @var{lx}, @var{ux},
+## @var{ly}, @var{uy}, "~>")
+## @end group
+## @end example
+##
+## @noindent
+## produces an xyerrorbar plot of @var{y} versus @var{x} in which
+## @var{x} errorbars are drawn from @var{x}-@var{lx} to @var{x}+@var{ux}
+## and @var{y} errorbars from @var{y}-@var{ly} to @var{y}+@var{uy}.
