% @deftypefn {Function File} {} bar (@var{x}, @var{y})
% Given two vectors of x-y data, @code{bar} produces a bar graph.
%
% If only one argument is given, it is taken as a vector of y-values
% and the x coordinates are taken to be the indices of the elements.
%
% If two output arguments are specified, the data are generated but
% not plotted. For example,
%
% @example
% bar (x, y);
% @end example
%
% @noindent
% and
%
% @example
% [xb, yb] = bar (x, y);
% plot (xb, yb);
% @end example
%
% @noindent
% are equivalent.
