How to plot two lines on the same graph

So these are my variables: x = [1:10] y = [1:10] z = [2:11]

And I know to plot them each separately, I type this for one: plot(x,y,'b*')

And this for the other: plot(x,z,'b-')

But how do I write it so that both show up on the same graph?

plot(x,y,'b*')
hold on;
plot(x,z,'b-')

Answer 2

plot(x,y,'b*') hold on plot(x,z,'b-') hold off

Don't forget to put hold off in case you want to create a separate graph not on the same plot.

You don't need to take hold off the first plot to keep it from applying on the second plot. Hold applies on a plot-specific basis. When you plot on the separate graph, it does not have "hold on" because you applied it on the first graph. See example:

subplot(2,1,1);
plot(rand(10, 1), 'b*-');
hold on
% Add a red line.
plot(rand(10, 1), 'r*-');

subplot(2,1,2);
plot(rand(10, 1), 'b*-');
% Plot red line.  Blows away blue line because hold is off
plot(rand(10, 1), 'r*-');
