Need to delete the previous points in a plot while plotting continously

During the matlb plotting of some set of points the previous points at previous time step should be deleted and continue with the further plotting.
x = [1,2,3,4,5];
y = [3,4,5,6,7];
plot(x,y,'-o');
so when its plotting for x(2) and y(2), the points of x(1) and y(1) should be deleted/unmarked on the plot.

Just to be clear - Do you to show one point at a time?
If yes, then what should be the time gap between consecutive points? Should the line be in the background?
If no, then please specify.
i want to show one point at a time and time gap between consecutive points can be 1 second and line should be visible in background

Change colors and other properties as you like/prefer.
x = [1,2,3,4,5];
y = [3,4,5,6,7];
plot(x, y, 'r')
hold on
h = animatedline('Marker', 'o', 'Color', 'k');
xlim([0 10])
ylim([0 10])
for k=1:numel(x)
addpoints(h, x(k), y(k));
pause(1)
drawnow
clearpoints(h)
end

Thank you so much, it helped me a lot!
You are welcome!

Hi this concept of erasing the previous points can be achieved without using the animated line function. Because i see this clearpoints cannot be used without using the animated line function. So is there any other method to work on this?
