Contour labels are rotated to match the local line ## orientation and centered on the line. The position of labels along the ## contour line is chosen randomly. ## ## If the argument @var{h} is a handle to a contour group object, then label ## this plot rather than the one in the current axes returned by @code{gca}. ## ## By default, all contours are labeled. However, the contours to label can be ## specified by the vector @var{v}. If the @qcode{"manual"} argument is ## given then the contours to label can be selected with the mouse. ## ## Additional property/value pairs that are valid properties of text objects ## can be given and are passed to the underlying text objects. Moreover, ## the contour group property @qcode{"LabelSpacing"} is available which ## determines the spacing between labels on a contour to be specified. The ## default is 144 points, or 2 inches. ## ## The optional return value @var{h} is a vector of graphics handles to ## the text objects representing each label. ## The @qcode{"userdata"} property of the text objects contains the numerical ## value of the contour label. ## ## An example of the use of @code{clabel} is ## ## @example ## @group ## [c, h] = contour (peaks (), -4 : 6); ## clabel (c, h, -4:2:6, "fontsize", 12); ## @end group ## @end example ## ## @seealso{contour, contourf, contour3, meshc, surfc, text} ## @end deftypefn function h = clabel (c, varargin) have_hg = false; have_labelspacing = false; label_spacing = 144; # 2 inches in points if (nargin < 1) print_usage (); elseif (nargin == 1) hparent = gca (); else arg = varargin{1}; if (isscalar (arg) && ishandle (arg) && strcmp (get (arg, "type"), "hggroup")) try get (arg, "contourmatrix"); catch error ("clabel: H must be a handle to a contour group"); end_try_catch have_hg = true; hg = arg; varargin(1) = []; else hparent = gca (); endif endif if (length (varargin) > 0 && isnumeric (varargin{1})) v = varargin{1}(:); varargin(1) = []; else v = []; endif idx = strcmpi (varargin(1:2:end), "manual"); if (any (idx)) error ('clabel: "manual" contour mode is not supported'); endif idx = find (strcmpi (varargin(1:2:end), "labelspacing"), 1); if (! isempty (idx)) have_labelspacing = true; label_spacing = varargin{2*idx}; varargin(2*idx+(-1:0)) = []; endif if (have_hg) if (! isempty (v)) if (have_labelspacing) set (hg, "textlistmode", "manual", "textlist", v, "labelspacing", label_spacing, "showtext", "on"); else set (hg, "textlistmode", "manual", "textlist", v, "showtext", "on"); endif else if (have_labelspacing) set (hg, "showtext", "on", "labelspacing", label_spacing); else set (hg, "showtext", "on"); endif endif htmp = findobj (hg, "type", "text"); if (! isempty (varargin)) set (htmp, varargin{:}); endif else htmp = __clabel__ (c, v, hparent, label_spacing, [], varargin{:}); endif if (nargout > 0) h = htmp; endif endfunction %!demo %! clf; %! colormap ('default'); %!
