%% Exclude Objects from Graph Legend
% This example shows how to plot several lines and create a legend that includes 
% descriptions for a subset of the lines. 
% 
% Plot four lines and return each chart line object as an output argument 
% from the |plot| function.

p2 = plot(x,y2);

y3 = exp(0.3*x).*sin(6*x);

y4 = exp(0.4*x).*sin(6*x);

% Create a legend in the lower left corner of the axes. Include descriptions 
% for only the first and last lines in the legend by specifying |p1| and |p4| 
% as the first input argument.
