How to add extra text to plot legend?

Hi, guys

Let us suppose that I have the following simple code:

clc; clear all; close all;

x = linspace(0, 2*pi, 100);

figure
hold on;grid on; box on;
plot(x,sin(x));
plot(x, cos(x));
plot(x, tan(x));
axis([0 2*pi -4 4]);
legend('sin', 'cos', 'tan'); 

My goal is to add some extra text in the legend box as shown in the following image example (image modified with gimp):

Can you help me to codify this task?

You can try legend title.

Thanks! Is it possible to put the title below the legend instead of above?
