Plot every nth data point

So I have a 1:3002 matrix/vector and I want to plot every 30th data point against time (so t=30 for the 30th data point, t=60 for the 60th etc) How do I do this? Is this even possible?

v = your vector
t = 1:numel(v);
plot(t(30:30:end),v(30:30:end));  % <-- assuming you want to start at 30th element
