How can I plot time data so that it starts at zero seconds?

I have an uneven time data, and I want to get it to start at t=0 instead of 3.1. Basically, I just want to shift everything over 3.1 seconds. Here is the simple code. (My actual time data is much more complicated but if you can make this work then I can apply it to my data.) Thanks, Noah

time = [3.1 4.2 5.1 6.2];

y = [5 7 4 3];

plot(time,y)

Hi Noah,

Have you tried this:

    time = time - time(1);

Brilliant! Thanks, wish I could have figured that out for myself...
