Introduction
Subplots allow us to plot multiple charts on the same figure in a grid. The axes are created in tiled positions. We can create subplots using the subplot command. For example,
subplot(m,n,k)
divides the figure into m x n grid and k is the kth subplot in the m x n grid.
Let’s create subplots for four sample trigonometric functions like:
- sin(x)
- cos(x)
- tan(x)
- sin(x)*cos(x)
We will create the four subplots in a 2×2 grid.
MATLAB Script
% Subplots Example - www.TestingDocs.com
% Creates 2x2 subplots
% Create x and y vectors
x = linspace(-2*pi,2*pi,100);
y1 = sin(x);
y2 = cos(x);
y3 = tan(x);
y4 = sin(x).*cos(x);
% Create 4 Subplots
subplot(2,2,1);
plot(x,y1);
xlabel('x - axis')
ylabel('y - axis')
title('sin(x) plot');
grid on;
subplot(2,2,2);
plot(x,y2);
xlabel('x - axis')
ylabel('y - axis')
title('cos(x) plot');
grid on;
subplot(2,2,3);
plot(x,y3);
xlabel('x - axis')
ylabel('y - axis')
title('tan(x) plot');
grid on;
subplot(2,2,4);
plot(x,y4);
xlabel('x - axis')
ylabel('y - axis')
title('sin(x)*cos(x) plot');
grid on;
