How to plot data from an external MAT file against a time domain?

I have a very large set of data that is meant to represent an ICP composite signal that must be plotted against a time domain. When I try loading in the data and plotting it against time, it informs me that the vectors are not of the same length. I've tried linspace and setting the icpcomposite as an array of zeros set to the length of 't', but nothing seems to work so far.

If you want to plot whole time series:

ns = length(icpcomposite);
t = (0:ns-1)/fs;
plot(t, icpcomposite);

If you want to plot a portion of data:

ns = 1000;  % for example (<= total samples in data)
t = (0:ns-1)/fs;
plot(t, icpcomposite(1:ns));
