plotting 3-D data in 2-D

Hi again,
I have a 3D matrix (test=rand(3,3,4)) and I'm trying to plot each 2D entry through the third dimension [i.e. plot nine lines: (1,1,:),(1,2,:) and so on]. I'm not exactly sure how to do this, and can't get it to work with plot or plot3.
Any ideas?
Thanks,
Don

test = repmat(magic(3),[1 1 4]); %each vector into the third dimension will be the same (so we can verify accuracy)
test2 = reshape(permute(test,[3 2 1]),size(test,3),[]); %permute it and reshape it so that each column represents one vector into the third dimension
plot(test2) %plot it

I've been fiddling around with this code and was wondering, is there a way to print the data from each row on a separate graphs? So for this 3x3 matrix have the output 3 charts with three lines each.

doc subplot
and then a for loop to do the work.
