hello, i have ten signals, each one have the same length, [1x1200], i want to plant them as one time series and while to show the variation for ten different signals, i want to plot the variance which could show the variance of the signals.

I would take the mean of the signals and the standard deviation, std, and plot those.
A preferable alternative to the std() would be the ‘standard error’, std()/sqrt(10).
