%% Add Plot to Existing Graph % This example shows how to add a plot to an existing graph. % % Plot of a sine wave along the domain [0,5]. % Copyright 2015 The MathWorks, Inc. x1 = linspace(0,5); y1 = sin(x1); figure % new figure window plot(x1,y1) %% % Use |hold on| to retain the line plot and add a new plot to the % graph. Add a stem plot along the domain [0,8]. Then, use |hold % off| to reset the hold state so that new plots replace existing plots, % which is the default behavior. hold on x2 = 0:0.5:8; y2 = 0.5*sin(x2); stem(x2,y2) hold off % reset hold state %% % MATLAB(R) rescales the axis limits each time a new plot is added to a % graph.
