custom use of heavisde?

I want to make a function just like the one in attached photo using heaviside command

The graph i get by using my following code,does not continue after t=2

I am trying my following code:(how can i change this code to get output plot like the attached photo)

clc
clear all
close all
syms t
x=[heaviside(t)-heaviside(t-1)]+heaviside(t-2)

ezplot(x)
axis([-0.5 4 -0.25 1.5])

How to atomate it?

x1 = [1 1 -1 -1 1 1];
x2 = [0 1 1 2 2 3];
y = heaviside(x1);
plot(x2,y)
xlim([-0.5 3.5])
axis equal

Dear your code gives desierd output but it lacks two main pre reqs

1) time must be symbolic variable

2)output should be plotted by using ezplot command not plot,

as i have to using this function for computing fourier transform that requires symbolic variables

[darova]

Hell im good

syms t
x = heaviside(t-2)-heaviside(t-1)+1;
ezplot(x,[0 3])
xlim([-0.5 3.5])
axis equal

If I recall correctly in R2015a you needed to use fplot() instead of ezplot() for symbolic expressions.
