hi, I have sum of sequences of integer values, i need to draw it to see the similarity among them.

for ex. x= [1 2 5 6 7 0 0; 2 3 4 9 1 8 6 ; 56 23 89 3 0 0]; i used : plot(1:7,x(1:3,1:7))

but this is nor give me clear relations among these sequences

what is the best way to do that? thanks in advance

Accepted answer

Are you trying to compare different rows? If so, use

plot(1:7,x.')

or simply

plot(x.')

Right, notice the transpose that Honglei used. When a matrix of y values are given to plot, it plots down the columns, so if your data is by rows, you need to transpose it.
