This version seems to work better.

I still see some strange behavior.


* Try

    demo plotyy
    demo quiver3

  Both of these demos seem to work OK if run separately in fresh Octave
  sessions, but plotyy seems to be leaving some state that causes
  quiver3 to fail with

  octave:2> demo quiver3
  quiver3 example 1:
   [x,y]=meshgrid (-1:0.1:1); 
   z=sin(2*pi*sqrt(x.^2+y.^2)); 
   theta=2*pi*sqrt(x.^2+y.^2)+pi/2;
   quiver3(x,y,z,sin(theta),cos(theta),ones(size(z)));
   hold on; 
   mesh(x,y,z); 
   hold off;

  quiver3 example 1: failed
  get: invalid handle (= -1.22961)Press <enter> to continue: 
  quiver3 example 2:
   [x, y, z] = peaks (25);
   surf (x, y, z);
   hold on;
   [u, v, w] = surfnorm (x, y, z / 10);
   h = quiver3 (x, y, z, u, v, w);
   set (h, "maxheadsize", 0.33);

* Try

    demo quiver3
    demo ribbon

  Both of these seem to work OK if run separately in fresh Octave
  sessions, but quiver3 seems to be leaving some state that causes
  ribbon to do the wrong thing.  Maybe this is a hold problem?  I
  haven't looked at it yet.



* The refreshdata demo does not seem to be working correctly for me.
  I'm seeing

    octave:1> demo refreshdata
    refreshdata example 1:
     x = 0:0.1:10;
     y = sin (x);
     plot (x, y, "ydatasource", "y");
     for i = 1 : 100
       pause(0.1)
       y = sin (x + 0.1 * i);
       refreshdata();
     endfor
