However the type of plot can be ## modified with the @var{fun} argument, in which case the plots are ## generated by @code{feval (@var{fun}, @var{x}, @var{y})}. @var{fun} can be ## a function handle, an inline function, or a string of a function name. ## ## The function to use for each of the plots can be independently defined ## with @var{fun1} and @var{fun2}. ## ## If the first argument @var{hax} is an axes handle, then it defines ## the principal axis in which to plot the @var{x1} and @var{y1} data. ## ## The return value @var{ax} is a vector with the axis handles of the two ## y-axes. @var{h1} and @var{h2} are handles to the objects generated by the ## plot commands. ## ## @example ## @group ## x = 0:0.1:2*pi; ## y1 = sin (x); ## y2 = exp (x - 1); ## ax = plotyy (x, y1, x - 1, y2, @@plot, @@semilogy); ## xlabel ("X"); ## ylabel (ax(1), "Axis 1"); ## ylabel (ax(2), "Axis 2"); ## @end group ## @end example ## @seealso{plot} ## @end deftypefn function [ax, h1, h2] = plotyy (varargin) [hax, varargin] = __plt_get_axis_arg__ ("plotyy", varargin{:}); nargin = numel (varargin); if (nargin < 4 || nargin > 6) print_usage (); endif oldfig = []; if (! isempty (hax)) oldfig = get (0, "currentfigure"); endif unwind_protect hax = newplot (hax); ## FIXME: Second conditional test shouldn't be required. ## 'cla reset' needs to delete user properties like __plotyy_axes__. if (isprop (hax, "__plotyy_axes__") && isaxes (get (hax, "__plotyy_axes__")) == [true true]) hax = get (hax, "__plotyy_axes__"); else hax(2) = axes ("nextplot", get (hax(1), "nextplot")); endif [axtmp, h1tmp, h2tmp] = __plotyy__ (hax, varargin{:}); set (gcf, "currentaxes", hax(1)); unwind_protect_cleanup if (! isempty (oldfig)) set (0, "currentfigure", oldfig); endif end_unwind_protect if (nargout > 0) ax = axtmp; h1 = h1tmp; h2 = h2tmp; endif endfunction function [ax, h1, h2] = __plotyy__ (ax, x1, y1, x2, y2, fun1 = @plot, fun2) if (nargin < 7) fun2 = fun1; endif xlim = [min([x1(:); x2(:)]), max([x1(:); x2(:)])]; axes (ax(1)); h1 = feval (fun1, x1, y1); set (ax(1), "color", "none", "ycolor", getcolor (h1(1)), "xlim", xlim); set (gcf (), "nextplot", "add"); axes (ax(2)); colors = get (ax(1), "colororder"); set (ax(2), "colororder", [colors(2:end,:); colors(1,:)]); if (strcmp (get (ax(1), "autopos_tag"), "subplot")) set (ax(2), "autopos_tag", "subplot"); else set (ax, "activepositionproperty", "position"); endif ## Don't replace axis which has colororder property already modified if (strcmp (get (ax(1), "nextplot"), "replace")) set (ax(2), "nextplot", "replacechildren"); endif h2 = feval (fun2, ax(2), x2, y2); set (ax(2), "yaxislocation", "right", "color", "none", "ycolor", getcolor (h2(1)), "box", "off", "xlim", xlim); if (strcmp (get(ax(1), "activepositionproperty"), "position")) set (ax(2), "position", get (ax(1), "position")); else set (ax(2), {"outerposition", "looseinset"}, get (ax(1), {"outerposition", "looseinset"})); endif ## Restore nextplot value by copying value from axis #1 set (ax(2), "nextplot", get (ax(1), "nextplot")); ## Add invisible text objects that when destroyed, ## also remove the other axis t1 = text (0, 0, "", "parent", ax(1), "tag", "plotyy", "visible", "off", "handlevisibility", "off", "xliminclude", "off", "yliminclude", "off"); t2 = text (0, 0, "", "parent", ax(2), "tag", "plotyy", "visible", "off", "handlevisibility", "off", "xliminclude", "off", "yliminclude", "off"); set (t1, "deletefcn", {@deleteplotyy, ax(2), t2}); set (t2, "deletefcn", {@deleteplotyy, ax(1), t1}); ## Add cross-listeners so a change in one axes' attributes updates the other. addlistener (ax(1), "position", {@update_position, ax(2)}); addlistener (ax(2), "position", {@update_position, ax(1)}); addlistener (ax(1), "outerposition", {@update_position, ax(2)}); addlistener (ax(2), "outerposition", {@update_position, ax(1)}); addlistener (ax(1), "looseinset", {@update_position, ax(2)}); addlistener (ax(2), "looseinset", {@update_position, ax(1)}); addlistener (ax(1), "view", {@update_position, ax(2)}); addlistener (ax(2), "view", {@update_position, ax(1)}); addlistener (ax(1), "plotboxaspectratio", {@update_position, ax(2)}); addlistener (ax(2), "plotboxaspectratio", {@update_position, ax(1)}); addlistener (ax(1), "plotboxaspectratiomode", {@update_position, ax(2)}); addlistener (ax(2), "plotboxaspectratiomode", {@update_position, ax(1)}); addlistener (ax(1), "nextplot", {@update_nextplot, ax(2)}); addlistener (ax(2), "nextplot", {@update_nextplot, ax(1)}); ## Store the axes handles for the sister axes. if (ishandle (ax(1)) && ! isprop (ax(1), "__plotyy_axes__")) addproperty ("__plotyy_axes__", ax(1), "data", ax); elseif (ishandle (ax(1))) set (ax(1), "__plotyy_axes__", ax); else error ("plotyy.m: This shouldn't happen.
