How can I plot an average line through this line graph

How can i plot the average of these line graphs onto the same graph?

Answer 1

[Marco Wassmer]

assuming your data is stored in the vectors x1....x8 of the same length:

sum each component and divide by the number of lines:

x_mean=sum([x1,x2,x3,x4,x5,x6,x7,x8],2)./8

The plot in the plot:

plot(gca,time,x_mean);

if your time vectors are not the same then you will have to interpolate

Answer 2

[Thorsten]

You store the values of each line in the rows of matrix X. Then use

plot(mean(X))
