Plot in increments of 30 seconds

Hello,

I wrote this script below which plots data over a period of 120 seconds, and divded it into increments of 30 seconds. I'm curious how to simplify this so I don't have to do it manually each time? Can it be done both with and without a for loop?

Thank you!

time30=find(x==30);
hold on
plot(x(1:time30),signal(1:time30));

time60=find(x==60);
hold on
plot(x(time30:time60),signal(time30:time60));

time90=find(x==90);
hold on
plot(x(time60:time90),signal(time60:time90));

time120=find(x==120);
hold on
plot(x(time90:time120),signal(time90:time120));

if you want to plot every 30-second segment as its own line object:

segment = reshape(1:120,30,4);

for i = 1:size(segment,2)
    plot(x(segment(:,i)),signal(segment(:,i)));
    hold on;
end

Let me know if this is what you wanted
