What do I add to the code after plot(stim) so that each iteration is displaced from one anohter on the x axis? Each iteration of the signal is represented with a different color on the plot.

I am not certain what you want to do. If you want the different waveforms to appear consecutively, plot them against an independent variable vector and then offset that vector.
Try simething like this:
t = linspace(0, 100, 101);
y1 = sin(2*pi*t*5/max(t));
y2 = cos(2*pi*t*10/max(t));
plot(y1) % Plot Together Without Indepdent Variable
hold on
hold off
title('Plot Together Without Indepdent Variable')
plot(t, y1) % Plot Together With Indepdent Variable
hold on
hold off
title('Plot Together With Indepdent Variable')
plot(t, y1) % Plot Consecutively With Indepdent Variable
hold on
plot(t+t(end), y2)
hold off
title('Plot Consecutively With Indepdent Variable')

In your loop, you can just create an x that gets shifted on each iteration
stim = ......
x = 5000 * i + (1 : length(stim)); % Shifts over by 5000 for each i
plot(x, stim)
