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") ## @end group ## @end example ## ## @seealso{barh, hist, pie, plot, patch} ## @end deftypefn ## Author: jwe function varargout = bar (varargin) varargout = cell (nargout, 1); [varargout{:}] = __bar__ (true, "bar", varargin{:}); endfunction %!demo %! clf; %! y = rand (11, 1); %! h = bar (y); %! set (h, 'ydata', sort (rand (11, 1))); %! title ('bar() graph'); %!demo %! clf; %! h = bar (rand (5, 3)); %! set (h(1), 'facecolor', 'r'); %! set (h(2), 'facecolor', 'g'); %! set (h(3), 'facecolor', 'b'); %! title ('bar() graph w/multiple bars'); %!demo %! clf; %! h = bar (rand (5, 3), 'stacked'); %! title ('bar() graph with stacked style');
