Create a plot for local max peaks given a certain time range.

This is the code I am running for an ECG data.
sf = 399.0698; %sampling frequency (Hz), samples per second
T = 1/sf;
timeSeries = T:T:600.8122; %time intervals
% graph with circled peaks (needs debugging)
[pks,locs] = findpeaks(y(1,:),'MinPeakDistance',0.3);
%y(1,:)is the signal I have filtered; its points traverse horizontally on row 1
% timeSeries is my time intervals on my X axis
I have a signal y(1,:) with a sampling frequency of 399.0698 and the total length of signal is 600s. I have found the local max for the signal y(1,:) I would like to plot a graph such that the peaks are circled and I can choose which part of the signal to show. Example 590-591seconds.

It's unclear what some of your variables are and how they relate to each other. For example, what's the second row of y? How does timeSeries (1x239766) related to y (2x100)? What is x?
Here's how to circle the peaks when (x,y(1,:)) is used to plot the data.
To address the time cutoffs of 590-591, I'll need more info.
