I've a problem to combine 2 graphs into 1 graph. The data is taken from Read EDF file. Then I did the plotting for 2 different graphs. Then I get this graph
if you look at those graphs closely, actually both of them can be concatenated together, so that the second graph on the right started from 10-20, continuing the first graph on the left. But I can't figure it out how to do it. For your info, I also attached the code in here, so that it's clear what I mean. Thank you
tt = edfread('example.edf');
info = edfinfo('example.edf');
fs = info.NumSamples/seconds(info.DataRecordDuration);
recnum = 1;
signum = 1;
t = (0:info.NumSamples(signum)-1)/fs(signum);
y1 = tt.(signum){recnum};
recnum = 2;
signum = 1;
y2 = tt.(signum){recnum};
subplot(1,2,1); plot(t,y1); subplot(1,2,2); plot(t,y2)

I do not have your files, however this is straightforward —
t1 = linspace(0, 10, 250);
signal1 = randn(size(t1));
t2 = linspace(0, 15, 250);
signal2 = randn(size(t2));
figure
tiledlayout(1,2)
nexttile
plot(t1,signal1)
nexttile
plot(t2,signal2)
figure
plot(t1, signal1)
hold on
plot(t2+t1(end), signal2)
hold off
I kept them different colours for clarity, and they will be plotted this way by default. It is straightforward to set the colours to be the same.

by the way, the file can refer to here, the "example.edf" file provided in the MATLAB. Anyway, it already works, thank you :)
