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

13 views (last 30 days)
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.

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

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?
