How to plot values over time?

I have an output that spits out 60 different values over the course of N=60 timesteps. How can I plot these values vs time? My current code is:

for n=1:N
  plot(T(n),rate(4,10,n))
end

rate(4,10,n) indicates the value at i=4 and j=10 of that matrix

You could add a drawnow() or pause() after your plot() call.

You might also want to see animatedline() . It is also common to use waterfall plots with x being the time axis.

I keep getting a blank graph. rate(:,:,n) is an 11,14 matrix at timestep n. I specify rate(4,10,n) because there is only one number in that matrix, at (4,10)

The default marker is empty for plot, and when you only plot one point at a time there will be no line to connect. You should specify a marker, like

plot(T(n), rate(4,10,n), '*')

However you should only do that if you want the position to be "animate". If you just want to draw all of them, then you should not use a loop and should instead use

plot(T(1:n), rate(4, 10, 1:N))
