Hello,
I want to plot a set of binary values such that each binary value will be shown for 50 seconds. I tried like this but was unable to get the pulse signal of binary values(0 and 1). binary =[1 1 0 1 0 0 1 0];assume this is my binary data
for l=1:1:length(binary)
for t=i:1:i+50
plot(t,binary(l),'-r');
ylim([-2 2]);
end
i=i+1;
end
can someone suggest in plotting this binary data(as I want to plot the data in real time).
Thank you.

If you want to show each value in binary for 50 seconds
binary =[1 1 0 1 0 0 1 0];
figure;
for idx = 1 : length(binary)
stem(0,binary(idx));
xlim([-1 1]);
ylim([0 1.5]);
title(['Binary (' num2str(idx) ')']);
drawnow;
pause(50);
end

Thanks.Can I know how to show the binary plot as square pulse as shown in the below figure instead of stem representation.

Sure! There are many ways to do this, but replace stem with bar and you're halfway there:
bar(1:8,binary(end-7:end),'BarWidth',1);
If you want something more similar to what you've drawn, you should use line . But you should center the pulses over the values to avoid confusion.
stem is a more correct way to represent the data, since values are not defined between integers.
