%% Combine Line and Stem Plots % This example shows how to combine a line plot and two stem plots. Then, it % shows how to add a title, axis labels, and a legend. % % Create the data and plot a line. % Copyright 2015 The MathWorks, Inc. x = linspace(0,2*pi,60); a = sin(x); b = cos(x); plot(x,a+b) %% % Add two stem plots to the axes. Prevent new plots from replacing existing % plots using |hold on|. hold on stem(x,a) stem(x,b) hold off %% % Add a title, axis labels, and a legend. Specify the legend descriptions % in the order that you create the plots. title('Linear Combination of Two Functions') xlabel('Time in \musecs') ylabel('Magnitude') legend('a+b','a = sin(x)','b = cos(x)') %% %
