Add as many legend you want to a single figure

Example
```% Create diagram
function Example
figure(1)
clf
hold on

x = [1:10];

plot(x, x + 0.0, 'b', 'LineWidth', 2, 'DisplayName', 'First')
plot(x, x + 0.2, 'r', 'LineWidth', 2, 'DisplayName', 'First')
plot(x, x + 0.4, 'g', 'LineWidth', 2, 'DisplayName', 'First')
plot(x, x + 0.6, 'c', 'LineWidth', 2, 'DisplayName', 'First')
plot(x, x + 0.8, 'k', 'LineWidth', 2, 'DisplayName', 'First')

plot(x, 0*x + 5 + 0.0, 'b-', 'LineWidth', 1)
plot(x, 0*x + 5 + 0.2, 'r-', 'LineWidth', 1)
