A marker is plotted at each point ## defined by the points in the vectors @var{x} and @var{y}. The size of ## the markers used is determined by the @var{s}, which can be a scalar, ## a vector of the same length of @var{x} and @var{y}. If @var{s} is not ## given or is an empty matrix, then the 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 a @var{n}-by-3 matrix defining ## the colors of each of the markers 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 the argument @code{"filled"} is given then the markers as filled. All ## additional arguments are passed to the underlying patch command. ## ## The optional return value @var{h} is a graphics handle to the hggroup ## object representing the points. ## ## @example ## @group ## x = randn (100, 1); ## y = randn (100, 1); ## scatter (x, y, [], sqrt(x.^2 + y.^2)); ## @end group ## @end example ## ## @seealso{plot, patch, scatter3} ## @end deftypefn function retval = scatter (varargin) [h, varargin, nargin] = __plt_get_axis_arg__ ("scatter", varargin{:}); if (nargin < 2) print_usage (); else oldh = gca (); unwind_protect axes (h); newplot (); tmp = __scatter__ (h, 2, "scatter", varargin{:}); unwind_protect_cleanup axes (oldh); end_unwind_protect endif if (nargout > 0) retval = tmp; endif endfunction %!demo %! x = randn (100, 1); %! y = randn (100, 1); %! scatter (x, y, "r"); %!demo %! x = randn (100, 1); %! y = randn (100, 1); %! scatter (x, y, [], sqrt (x.^2 + y.^2)); %!demo %! rand_10x1_data1 = [0.171577, 0.404796, 0.025469, 0.335309, 0.047814, 0.898480, 0.639599, 0.700247, 0.497798, 0.737940]; %! rand_10x1_data2 = [0.75495, 0.83991, 0.80850, 0.73603, 0.19360, 0.72573, 0.69371, 0.74388, 0.13837, 0.54143]; %! x = rand_10x1_data1; %! y = rand_10x1_data2; %! s = 10 - 10*log (x.^2 + y.^2); %! h = scatter (x, y, s, s, "s", "filled"); %!demo %! rand_10x1_data3 = [0.42262, 0.51623, 0.65992, 0.14999, 0.68385, 0.55929, 0.52251, 0.92204, 0.19762, 0.93726]; %! rand_10x1_data4 = [0.020207, 0.527193, 0.443472, 0.061683, 0.370277, 0.947349, 0.249591, 0.666304, 0.134247, 0.920356]; %! x = rand_10x1_data3; %! y = rand_10x1_data4; %! s = 10 - 10*log (x.^2 + y.^2); %! h = scatter (x, y, [], "r", "s", "filled"); %!demo %! rand_10x1_data5 = [0.777753, 0.093848, 0.183162, 0.399499, 0.337997, 0.686724, 0.073906, 0.651808, 0.869273, 0.137949]; %! rand_10x1_data6 = [0.37460, 0.25027, 0.19510, 0.51182, 0.54704, 0.56087, 0.24853, 0.75443, 0.42712, 0.44273]; %! x = rand_10x1_data5; %! y = rand_10x1_data6; %! s = 10 - 10*log (x.^2 + y.^2); %! h = scatter (x, y, [], "r", "s"); %!demo %! n = 500; %! x = rand (n,1); %! y = rand (n,1); %! idx = ceil (rand (n,1)*3); %! colors = eye(3)(idx, :); %! scatter (x,y,15, colors, "filled");
