How can i add mean and Std horizontal lines to all plots?? (eg.ym1 and ys1 are mean and std of subplot subplot(3, 2, 1))
figure
subplot(3, 2, 1)
ym1=mean(distlocus1)
ys1=std(distlocus1)
plot(distlocus1)
title('Início - 15''')
subplot(3, 2, 2)
ym2=mean(distlocus2)
ys2=std(distlocus2)
plot(distlocus2)
title('15'' - 30''')
subplot(3, 2, 3)
ym3=mean(distlocus3)
ys3=std(distlocus3)
plot(distlocus3)
title('30'' - Intervalo''')
subplot(3, 2, 4)
ym4=mean(distlocus4)
ys4=std(distlocus4)
plot(distlocus4)
title('Intervalo'' - 60''')
subplot(3, 2, 5)
ym5=mean(distlocus5)
ys5=std(distlocus5)
plot(distlocus5)
title('60'' - 75''')
subplot(3, 2, 6)
ym6=mean(distlocus6)
ys6=std(distlocus6)
plot(distlocus6*ym6)
title('75'' - Final''')

I would plot them as:
plot(xlim, [1 1]*ym1, '-r', xlim, ym1+[1 -1; 1 -1]*ys1, '-g')
and so for the others.
This plots the mean in red, and the the two standard deviation lines in green. This uses xlim, so it will automatically span the x-axis limits.

The code is ok to mean and std lines. But, how can i put y variable in that code??

I was thinking of something like this:
subplot(3, 2, 1)
ym1=mean(distlocus1)
ys1=std(distlocus1)
plot(distlocus1)
hold on
plot(xlim, [1 1]*ym1, '-r', xlim, ym1+[1 -1; 1 -1]*ys1, '-g')
hold off
title('Início - 15''')
So add the hold calls, and the new plot call, to plot the mean and standard deviation. This applies to all the subplots, so all you need to do is to change ‘ym1’ and ‘ys1’ in the other subplots to their appropriate variables.
