I want to plot the state transitions chain of markov process. My original state transitions matrix is 56 by 1000. But here I give a small example

for example, if I have to plot this matrix, where each column represents discrete lifetime for one individual.

sequence = [1 1 1 1 2 2 2 2 2 3;...

1 1 1 1 1 1 1 1 1 1;...

1 1 1 1 1 1 1 2 2 2;...

1 1 1 1 1 1 1 1 1 1;...

2 2 2 2 2 2 2 2 2 2; ...

2 2 2 2 2 2 2 3 3 3; ...

2 3 3 3 3 3 2 2 2 2; ...

2 2 2 2 2 2 4 4 4 4]

age = (25:33)

How can I put on x axis the age variable and y axis the matrix sequence columnwise?

You may use the following line of code:

plot(age,sequence(:,1:end))

To create labels for the lines plotted, you may use the legend function.

Thank you, that worked perfectly!
