If @var{s} ## is not given, or is an empty matrix, then a default value of 8 points is ## used. ## ## The color of the markers is determined by @var{c}, which can be a string ## defining a fixed color; a 3-element vector giving the red, green, and blue ## components of the color; a vector of the same length as @var{x} that gives ## a scaled index into the current colormap; or an @nospell{Nx3} matrix defining ## the RGB color of each marker individually. ## ## The marker to use can be changed with the @var{style} argument, that is a ## string defining a marker in the same manner as the @code{plot} command. ## If no marker is specified it defaults to @qcode{"o"} or circles. ## If the argument @qcode{"filled"} is given then the markers are filled. ## ## Additional property/value pairs are passed directly to the underlying ## patch object. ## ## 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 graphics handle to the created patch ## object. ## ## Example: ## ## @example ## @group ## x = randn (100, 1); ## y = randn (100, 1); ## scatter (x, y, [], sqrt (x.^2 + y.^2)); ## @end group ## @end example ## ## @seealso{scatter3, patch, plot} ## @end deftypefn function retval = scatter (varargin) [hax, varargin, nargin] = __plt_get_axis_arg__ ("scatter", varargin{:}); if (nargin < 2) print_usage (); endif oldfig = []; if (! isempty (hax)) oldfig = get (0, "currentfigure"); endif unwind_protect hax = newplot (hax); htmp = __scatter__ (hax, 2, "scatter", varargin{:}); unwind_protect_cleanup if (! isempty (oldfig)) set (0, "currentfigure", oldfig); endif end_unwind_protect if (nargout > 0) retval = htmp; endif endfunction %!demo %! clf; %! x = randn (100, 1); %! y = randn (100, 1); %! scatter (x, y, 'r'); %! title ('scatter() plot with red bubbles'); %!demo %! clf; %! x = randn (100, 1); %! y = randn (100, 1); %! c = x .* y; %! scatter (x, y, 20, c, 'filled'); %! title ('scatter() with colored filled bubbles'); %!demo %! clf; %! x = randn (100, 1); %! y = randn (100, 1); %! scatter (x, y, [], sqrt (x.^2 + y.^2)); %! title ({'scatter() plot'; ... %!
