MATLAB: Subplot doesn’t hold when plotting in for loop

2d plotsubplot

I'm trying to subplot many signals with time in a single figure using subplot by using command 'hold on' in a for loop.
Ex: x is a structure with time
s=[];
plotpos=0.85;
for i=1:10;
    s(i)=subplot(10,1,i,'Position', [0.175, plotpos, 0.8, 0.115]); 
    hold (s(i),'on'); grid on;
    plot(x.time,x.signals.values(:,i))
    plotpos=plotpos-0.14;
end
It deletes the previous subplots and adds a new one at next position instead of holding all previous subplots and adding new ones at new position.

Create the axes at first:
s       = [];
plotpos = 0.85;
for i = 1:10
  s(i) = axes('Position', [0.175, plotpos, 0.8, 0.115], ...
              'NextPlot', 'add', ...  % as done inside HOLD command
              'Grid',     'on');
  plotpos = plotpos-0.14;
end
Draw afterwards as often as you want:
for k = 1:10
  plot(x.time, x.signals.values(:, k), 'Parent', s(k));
end
