The vertices of the ## rectangles [@var{x}, @var{y}] are typically the output of @code{meshgrid}. ## over a 2-D rectangular region in the x-y plane. @var{z} determines the ## height above the plane of each vertex. If only a single @var{z} matrix is ## given, then it is plotted over the meshgrid ## @code{@var{x} = 1:columns (@var{z}), @var{y} = 1:rows (@var{z})}. ## Thus, columns of @var{z} correspond to different @var{x} values and rows ## of @var{z} correspond to different @var{y} values. ## ## The color of the mesh is computed by linearly scaling the @var{z} values ## to fit the range of the current colormap. Use @code{caxis} and/or ## change the colormap to control the appearance. ## ## Optionally the color of the mesh can be specified independently of @var{z} ## by supplying a color matrix, @var{c}. ## ## Any property/value pairs are passed directly to the underlying surface ## 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 ## surface object. ## ## @seealso{meshz, mesh, meshc, contour, surf, surface, ribbon, meshgrid, hidden, shading, colormap, caxis} ## @end deftypefn ## Author: Mike Miller <mtmiller@ieee.org> function h = waterfall (varargin) htmp = meshz (varargin{:}); set (htmp, "meshstyle", "row"); ## The gnuplot toolkit does nothing with the meshstyle property currently. toolkit = get (ancestor (htmp, "figure"), "__graphics_toolkit__"); if (strcmp (toolkit, "gnuplot")) warning ("waterfall: may not render correctly using toolkit '%s'", toolkit); endif if (nargout > 0) h = htmp; endif endfunction %!demo %! clf; %! colormap ('default'); %!
