%% Overlay Stairstep Plot and Line Plot
% This example shows how to overlay a line plot on a stairstep plot. 
%
% Define the data to plot.

alpha = 0.01;
beta = 0.5;
t = 0:10;
f = exp(-alpha*t).*sin(beta*t);

%%
% Display |f| as a stairstep plot. Use the
% |hold| function to retain the stairstep plot. Add a line plot of 
% |f| using a dashed line with star markers. 

stairs(t,f)
hold on 
plot(t,f,'--*')
hold off 

%%
% Use the |axis| function to set the axis limits. Label the _x_-axis and
% add a title to the graph. 

axis([0,10,-1.2,1.2])
xlabel('t = 0:10')
title('Stairstep plot of e^{-(\alpha*t)} sin\beta*t')
