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.

在 MATLAB Online 中打开

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?
