How to plot multiple lines in a graph?

I have a matrix with several 5 layers. I want to plot the numbers at a specific gridpoint for layers 2,3, and 4. How would I go about doing this?

Thanks for the help!

See plot()

Otherwise, I'd call this an unanswerably vague question.

There are already two answers for ways to plot multiple paired sets of x,y data, but x and y don't need to be vectors. They can be matrices, and there are multiple ways that they might be used. If or how that applied to the original problem is completely unknown. The documentation has examples.

x1=[2 3 4 5];
y1=[9 4 3 2];
x2=[11 20 30 50 ];
y2= [ 20 30 50 60];

plot(x1,y1) 
hold on 
plot(x2,y2)
hold off

This plot two line graphs on same plot

x = linspace(0,10,100)

y = x.^2 .* exp(-x)

yd = 2*x .* exp(-x) - x.^2 .* exp(-x)

plot(x,y,'-o','LineWidth',2.2,'MarkerSize',7 ,x,yd,':s','LineWidth',2.2,'MarkerSize',7)
