How do I show the for loop results over time?

I need to create a grapgh of player 2's score over the number of "trials". However, I can only see the last score of the 10,000 trial. How can I save all of the data such that I know the score for the nth trial?

n = 100000; %number of trials
score = zeros(n,2); % first column is player 1, 2nd column is player 2
for i = 1:n
    p1 = randi([1 2])
    p2 = randi([1 2])
    if p1+ p2 == 3
        score(i,:) = [ 1 0];
    else
       score(i,:) = [0 1];
    end
end

%check score for 99th trial:
score(99,:)

%check total score:
sum(score)

Using this code, how would I plot player 2's score over each of the trials?

[Kevin Phung]

plot(score(:,2)).
