How make separate plots of one timeseries

I have a Simulink model which outputs a timeseries 'y_ss' to the workspace. The timeseries 'y_ss' contains three columns of data: each column corresponds to a state of my system. I want to make a plot for each column of data separately so that I can see the behavior of each state of my system. I've tried the following code to plot my first state (first data column) by itself:

clear all;
sim('HW2_P5model');

figure;
hold on;
plot(y_ss.Data:1),'b-');
xlabel('Time (sec)');
ylabel('Current (A)');
title('RLC Circuit Simulation');
legend('i_{L2}');

This doesn't give me anything at all. How can I plot each of the data columns individually in its own figure?

Thanks,

What is the size of y_ss.Data. Type

size(y_ss.Data)

Answer 1

If the size of y_ss is nx3

sim('HW2_P5model')
time=y_ss.Time
y1=y_ss(:,1)
y2=y_ss(:,2)
y3=y_ss(:,3)
plot(t,y1,t,y2,t,y3)

The workspace says that y_ss is 1x1 timeseries. I tried implementing your solution to plot just the first data column:

clear all;
sim('HW2_P5model');

t=y_ss.Time;
y1=y_ss(:,1);
plot(t,y1);

and get the following error:

Error using timeseries/plot (line 27) The plot method can only be used for a single timeseries object

Error in HW2_P5 (line 6) plot(t,y1);

If I try to access y_ss(:,2), I also get an error saying that index exceeds matrix dimensions.

Any thoughts?

What is the size of y_ss.Data? and avoid using clear all
