Details:

Hi, I've tried a number of different commands to save a plot, this script
worked in the previous version I had installed (3.6.4) but not longer works in
the newer 3.8.1 version.
I simply get no output at all, no file and no error displayed. Also when the
graph plot window is set to "visible" the window suffers graphically glitches
and won't respond to clicks or any input.

function dostuff()
  i = 0;
  col = ["r","g","b","k","5","6","y"];
  mass = 20*(1.66e-27);
  var2 = load("Velpertd.txt");
  j=figure(1)#,"visible","off");
  plot(var2(:,1)+27,var2(:,3)/1e6,"-m","linewidth",3);
  hold;
  x = 1;
  for  i = 2:1:8;
    filname = strcat(num2str(i),"pi__10.dat");
    var = load(filname);
    type = strcat("-",col(x));
    plot(var(:,1)*1e6,(var(:,2)/mass)/1e6,type,"linewidth",3);
    x=x+1;
  endfor

  xlabel("x position in microns");
  ylabel("Velocity (10^{6}ms^{-1})");
  tit = strcat("Ion velocity perturbation at t = 100fs for varying
ionisations");
  title(tit);
  axis([25,35,0,1]);
  grid('on');
  set(gca(),'xtick',25:0.5:35);
  set(gca(),'ytick',0:0.1:1);
  h =  legend("Perturbation Used","2","3","4","5","6","7","8");
  legend location northeast;
  #outfilnam=strcat("");
  hold
  saveas(j,"AApxim100.png","png")
endfunction
dostuff()
