Details:

The following function does not honor subplot() chart sizing.
The problem only seems to occur when plotyy is used, plot() works fine.

This particular example is not very realistic because in this example, without
the commented hold on statement, later charts would be replacing earlier
charts, which is pointless.  But there may be other cases where plotyy() or
other plotting functions don't correctly honor subplot.


function hold_prob
  close all; figure;
  x = linspace(0,10,10);
  y = rand(4*4,10);
  for ia=1:2
    for ip=1:4
      subplot(2,2,ip);
      %hold on;
      grid on;
      iy = (ia-1)*4 + ip;
      plotyy(x,y(iy,:), x,y(iy+1,:));
      drawnow;
    end
  end
end
