Rename h to hax. Rename tmp to htmp. * scripts/plot/surfc.m: Check __plt_get_axis_arg__ before calling newplot. Remove obsolete code checking for input axis handle. Use cellfun to eliminate for loop. diff -r 3e1b24a2454a -r 1118d566bcd4 scripts/plot/surf.m --- a/scripts/plot/surf.m Tue Jul 23 16:06:07 2013 +0200 +++ b/scripts/plot/surf.m Tue Jul 23 16:26:43 2013 +0200 @@ -42,24 +42,26 @@ function retval = surf (varargin) - [h, varargin] = __plt_get_axis_arg__ ("surf", varargin{:}); + [hax, varargin] = __plt_get_axis_arg__ ("surf", varargin{:}); - oldh = gca (); + oldfig = ifelse (isempty (hax), [], get (0, "currentfigure")); unwind_protect - axes (h); - newplot (); - tmp = surface (varargin{:}); + hax = newplot (hax); + + htmp = surface (varargin{:}); - if (! ishold ()) - set (h, "view", [-37.5, 30], + if (! ishold (hax)) + set (hax, "view", [-37.5, 30], "xgrid", "on", "ygrid", "on", "zgrid", "on"); endif unwind_protect_cleanup - axes (oldh); + if (! isempty (oldfig)) + set (0, "currentfigure", oldfig); + endif end_unwind_protect if (nargout > 0) - retval = tmp; + retval = htmp; endif endfunction diff -r 3e1b24a2454a -r 1118d566bcd4 scripts/plot/surfc.m --- a/scripts/plot/surfc.m Tue Jul 23 16:06:07 2013 +0200 +++ b/scripts/plot/surfc.m Tue Jul 23 16:26:43 2013 +0200 @@ -24,52 +24,58 @@ ## then a typical vertex is (@var{x}(j), @var{y}(i), @var{z}(i,j)).
