## Produce a horizontal bar graph from two vectors of x-y data.
##
## 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.
##
## The default width of 0.8 for the bars can be changed using @var{w}.
##
## If @var{y} is a matrix, then each column of @var{y} is taken to be a
## separate bar graph plotted on the same graph.  By default the columns
## are plotted side-by-side.  This behavior can be changed by the @var{style}
## argument, which can take the values @code{"grouped"} (the default),
## or @code{"stacked"}.
##
## The optional input handle @var{h} allows an axis handle to be passed.
## Properties of the patch graphics object can be changed using
## @var{prop}, @var{val} pairs.
##
## The optional return value @var{h} is a graphics handle to the created
## bar series object.  See @code{bar} for a description of the use of the
## bar series.
