This is in contrast to ## @code{contour} which plots all of the contour lines at the same Z level ## and produces a 2-D plot. ## ## The level curves are taken from the contour matrix @var{c} computed by ## @code{contourc} for the same arguments; see the latter for their ## interpretation. ## ## The appearance of contour lines can be defined with a line style @var{style} ## in the same manner as @code{plot}. Only line style and color are used; ## Any markers defined by @var{style} are ignored. ## ## 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 output @var{c} are the contour levels in @code{contourc} format. ## ## The optional return value @var{h} is a graphics handle to the hggroup ## comprising the contour lines. ## ## Example: ## ## @example ## @group ## contour3 (peaks (19)); ## hold on; ## surface (peaks (19), "facecolor", "none", "EdgeColor", "black"); ## colormap hot; ## @end group ## @end example ## ## @seealso{contour, contourc, contourf, clabel, meshc, surfc, caxis, colormap, plot} ## @end deftypefn function [c, h] = contour3 (varargin) [hax, varargin, nargin] = __plt_get_axis_arg__ ("contour3", varargin{:}); oldfig = ifelse (isempty (hax), [], get (0, "currentfigure")); unwind_protect hax = newplot (hax); [ctmp, htmp] = __contour__ (hax, "auto", varargin{:}); unwind_protect_cleanup if (! isempty (oldfig)) set (0, "currentfigure", oldfig); endif end_unwind_protect if (! ishold ()) set (hax, "view", [-37.5, 30], "xgrid", "on", "ygrid", "on", "zgrid", "on"); endif if (nargout > 0) c = ctmp; h = htmp; endif endfunction %!demo %! clf; %! contour3 (peaks (19)); %! hold on; %! surface (peaks (19), 'facecolor', 'none', 'edgecolor', 'black'); %! colormap (hot (64)); %! axis tight; %! zlim auto; %! box off; %! hold off;
