How do I hold plots from a for loop?

Hi everyone,
I am trying to hold the plots produced in a for loop but I only get the last plot. What I have done so far is the following.
for i=1:30
plot(y(:,i))
hold;
end
Thanks in advance.

What is y? Or rather what size is it?
You should always use the
plot( hAxes,... )
version of the plot command, to specify a specific axes, especially if you are expecting 30 different figures as your comment to the answer below suggests.
It's not obvious how you want 30 different figures, but also want to hold the plots within a figure though. What are you expecting on each of these 30 figures?

for i=1:30
plot(y(:,i))
hold on
end
Or simply
plot(y)

Or you might be expecting this:
figure;
hold on;
y = rand(5,30) ;
for i=1:5
subplot(5,1,i) ;
plot(y(i,:))
end

+1: Now we find all possible solutions which might match the question.
Calling hold on repeatedly inside a loop seems like a wast of time for me. Although it will be some microseconds only, I prefer:
hAxes = axes('NextPlot', 'add'); % See source of: hold
for k = 1:5
plot(hAxes, y(:, k));
end
or for older Matlab versions, which used doubles as handle of the GUI objects:
plot(y(:, k), 'Parent', hAxes);
to avoid a misinterpretation of the handle as X-value.
