Plot multiple points in a for loop

Hello everyone, I have a for loop which is plotting different points over a certain amount of time. Right now the previous point is removed when the next one is added, but i would like to keep the old points.

n=100
for i=1:n+1
    plot(i,i,'r.','MarkerSize',10);
    axis([0 110 0 110])
    f(i) = getframe(gcf);
end

Hopefully someone can help me with that.

use hold

n=100

for i=1:n+1
    plot(i,i,'r.','MarkerSize',10);
    hold on
    axis([0 110 0 110])
    f(i) = getframe(gcf);
end
hold off

Create an animatedline then addpoints to that animatedline each time you step through your for loop.

Thanks @steven. This was a good solution. Using 'animatedline' rather than 'plot' later allowed me to add different colors and legend entries for each line, which would have been difficult with 'plot'.
