Superimpose step and line diagrams        

         This example demonstrates how to superimpose a line graph on a ladder graph . Define the data to plot .

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

         take f Show as ladder . Use hold The function preserves the ladder diagram . Add... With dotted lines marked with stars f Line graph .

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

         As shown in the figure ：

         Use axis Function to set the axis range . Mark x Axis and add a title to the drawing .

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

         As shown in the figure ：

Merge line and needle charts         

          This example demonstrates how to combine a line graph and two needle graphs . then , Show how to add a title 、 Axis labels and legends .

         Create data and draw a line .

x = linspace(0,2*pi,60);
a = sin(x);
b = cos(x);
plot(x,a+b)

         Add two needle graphs in the coordinate area . Use hold on Prevent new drawings from replacing existing drawings .

hold on
stem(x,a)
stem(x,b)
hold off

         Add the title 、 Axis labels and legends . Specify legend descriptions in the order in which you create drawings .

title('Linear Combination of Two Functions')
xlabel('Time in \musecs')
ylabel('Magnitude')
legend('a+b','a = sin(x)','b = cos(x)')
