Hi everybody, I am struggling to find the mean values of say 30 distinct time series representing the same phenomena. Is there a nice way to represent graphically the time series obtained from the mean values of the 30 distinct series? I would be very grateful for guidance. Kind regards, Massilon.

Think we need some more background here...mean over what, the 30 series at each time value, the mean of each series over time, what?
I really can't then decide what the graphical representation wanted sentence is referring to.

As dpb says, hard to guess. If you do mean, "the 30 series all have the same sample times, and I want to compute the mean of the 30 series at each sample time", and you are using R2016b or later, that sounds like you could use a timetable.
tt = array2timetable(yourDataAsColumns,'RowTimes',yourSampleTimes)
tt.MeanVal = mean(tt.Variables,2);
plot(tt.Time,tt.MeanVal)
Prior to R2016b, you could do essentially the same thing using an ordinary table.
