Plotting with MATLAB

Effective plots are important to synthesize the information into relevant and persuasive information. The following tutorial details some of the common data plotting functions within MATLAB.

Tutorial MATLAB Source Code

clear all; close all; clc
x = linspace(0,6);
y = sin(x);
z = cos(x);
h = figure(1);
plot(x,y,'r--')
hold on
plot(x,z,'b.-','LineWidth',3)
xlabel('x')
ylabel('values')
legend('y','z')
xlim([0 3]);
ylim([-1.5 1.5]);
saveas(h,'myPlot.png')
saveas(h,'myPlot.eps')

Resize Plot and Save Figures

clear all; close all; clc

x = linspace(0,10);
y = sin(x);

p1 = figure('rend','painters','pos',[10 10 900 600]);
plot(x,y)
legend('sin(x)')
ylabel('sin(x)')
xlabel('x')
saveas(p1,'myFigure1.png')

p2 = figure('rend','painters','pos',[10 10 300 200]);
plot(x,y)
legend('sin(x)')
ylabel('sin(x)')
xlabel('x')
saveas(p2,'Fig2_for_screens.png')
saveas(p2,'Fig2_for_documents.eps')
