Plot two time series in one figure(MATLAB)

Question

Suppose that we have these two series:

First_Series = [1, 1200; 2,1300; 3,100; 5,267;  6,2674; 7,1346];
Second_Series = [8, 1340; 9,2100; 10,1100];

In both series first column is x-axis and second column is y-axis. I want these two series in a same line-plot with different colors.

Answer 1

1. Call figure ; This creates a window to plot the graph
2. Call plot on the first one, this will plot the first series
3. Issue the command hold on; this holds the previously plotted graph window
4. Plot the second series--it will plot on the held graph

When you issue the command hold off; it will release the graph window. New plots will go to a new graph window.

Here's an example with your data set plotting red and green lines for the two series:

 figure;
 plot(First_Series(:,1), First_Series(:,2), 'r');
 hold on;
 plot(Second_Series(:,1), Second_Series(:,2), 'g');
 hold off;

You should get the following result:
