    x = Timestep; 
    y = LogPriceReturn; 
    plot(x,y, '.'); hold on
    title('Log Price Return');
    xlabel('Timestep');
    ylabel('Log Price Return');
    axis([1 n -1 1]);

How can I change this code to plot this graph as a line graph instead of just displaying the points

I assume the code you posted is in a loop. The most likely solution is something like this:

for loop_index = 1:last_value
    ... CODE ...
    x(loop_index) = Timestep; 
    y(loop_index) = LogPriceReturn; 
end
figure
plot(x,y)
title('Log Price Return')
xlabel('Timestep')
ylabel('Log Price Return')
axis([1 n -1 1])
grid
