## 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')
