Problem 4

% Part A
% Plots data from the US Energy csv file

set(0,'defaultAxesFontSize',16)
set(0,'defaultTextFontSize',16)
set(0,'defaultLineLineWidth',3)
data=dlmread('energy.csv',',',2,0);
h=figure(1)
plot(data(:,1),data(:,3),data(:,1),data(:,9)) %plots data from certain columns of the file
xlabel('Year') %creates x axis label
ylabel('Energy Used (BTU x 1 Trillion)') %creates y axis label
legend('Residential','Transportation','Location','Northwest') %creates legend and moves it to top right corner of graph
title('US Energy Consumption by Sector vs Time') %creates title
saveas(h,'figure_02.png')
print(h,'figure_02.png')

% Part B
% Plots cumulative data from the US Energy csv file

A = figure();
plot(data(:,1),data(:,3),data(:,1),data(:,9)) %plots data from certain columns of the same file
xlabel('Year') %creates x axis label
ylabel('Cumulative Energy Used (BTU * 1e6 Trillion)') %creates y axis label
legend('Residential','Transportation','Location','Northwest') %creates legend and moves it to top right corner of graph
title('Cumulative US Energy Consumption by Sector vs Time') %creates title
saveas(A,'figure_01')
print('figure_01');
