%% 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. % Copyright 2015 The MathWorks, Inc. x = linspace(0,5,500); y1 = exp(0.1*x).*sin(6*x); p1 = plot(x,y1); hold on y2 = exp(0.2*x).*sin(6*x); p2 = plot(x,y2); y3 = exp(0.3*x).*sin(6*x); p3 = plot(x,y3); y4 = exp(0.4*x).*sin(6*x); p4 = plot(x,y4); %% % 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. hold off legend([p1 p4],'e^{0.1x}sin(6x)','e^{0.4x}sin(6x)','Location','southwest') %% %
