% A simple script to graph the data in a txt file.

% Load the data into a matrix
data = readmatrix('yearmalefemale.txt');

% Extract the columns
year = data(:, 1); % First column
male = data(:, 2); % Second column
female = data(:, 3); % Third column

% Plot the number of males
plot(year, male, 'b'); % 'b' for blue line
hold on; % Keep the current plot

% Plot the number of females
plot(year, female, 'r'); % 'r' for red line

% Adding labels and legends
xlabel('Age');
ylabel('Population');
legend('Males', 'Females');
title('Population by Gender and Age in the UK (2014)');

% Display the graph
hold off;

data = load('averhighs.txt');
