+## Produce a bar graph from two vectors of X-Y data.
+##
+## If only one argument is given, @var{y}, it is taken as a vector of Y values
+## and the X coordinates are the range @code{1:numel (@var{y})}.
+##
+## The optional input @var{w} controls the width of the bars.  A value of
+## 1.0 will cause each bar to exactly touch any adjacent bars.
+## The default width is 0.8.
+##
+## 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 following values:
+##
+## @table @asis
+## @item @qcode{"grouped"} (default) 
+## Side-by-side bars with a gap between bars and centered over the X-coordinate.
+## 
+## @item  @qcode{"stacked"}
+## Bars are stacked so that each X value has a single bar composed of
+## multiple segments.
+##
+## @item @qcode{"hist"}
+## Side-by-side bars with no gap between bars and centered over the
+## X-coordinate.
+##
+## @item @qcode{"histc"}
+## Side-by-side bars with no gap between bars and left-aligned to the
+## X-coordinate.
+## @end table
+##
+## Optional property/value pairs are passed directly to the underlying patch
+## objects.
+##
+## If the first argument @var{hax} is an axes handle, then plot into this axis,
+## rather than the current axes returned by @code{gca}.
+##
+## The optional return value @var{h} is a vector of handles to the created
+## "bar series" hggroups with one handle per column of the variable @var{y}.
+## This series makes it possible to change a common element in one bar series
+## object and have the change reflected in the other "bar series".
+## For example,
+##
+## @example
+## @group
+## h = bar (rand (5, 10));
+## set (h(1), "basevalue", 0.5);
+## @end group
+## @end example
+##
+## @noindent
+## changes the position on the base of all of the bar series.
+##
+## The following example modifies the face and edge colors using
+## property/value pairs.
+##
+## @example
+## bar (randn (1, 100), "facecolor", "r", "edgecolor", "b");
+## @end example
+##
+## @noindent
+## The color of the bars is taken from the figure's colormap, such that
+##
+## @example
+## @group
+## bar (rand (10, 3));
+## colormap (summer (64));
+## @end group
+## @end example
+##
+## @noindent
+## will change the colors used for the bars.  The color of bars can also be set
+## manually using the @qcode{"facecolor"} property as shown below.
+##
+## @example
+## @group
+## h = bar (rand (10, 3));
+## set (h(1), "facecolor", "r")
+## set (h(2), "facecolor", "g")
+## set (h(3), "facecolor", "b")
