% Load the matrix |hwydata| from the example file |accidents.mat|.
% Create a scatter plot of the fifth column in |hwydata| against the left
% _y_-axis. Add a title and axis labels.

load('accidents.mat','hwydata')
ind = 1:51;
drivers = hwydata(:,5);
yyaxis left
scatter(ind,drivers)
title('Highway Data')
xlabel('States')
ylabel('Licensed Drivers (thousands)')

% Create a second scatter plot of the seventh column in |hwydata| against
% the right _y_-axis. Then, label the right _y_-axis.

pop = hwydata(:,7);
yyaxis right
scatter(ind,pop)
ylabel('Vehicle Miles Traveled (millions)')
