clear one plot in multiple (hold) figure

Hello,

I want to follow a point by plotting him every time. I want just plot the point not all previous points.

I've tried to use this code, but it gives all points.

x = 1:0.01:25;
y = sin(x);
n = numel(x);
%figure;
for i = 1:n
   
    h=plot(x(1:i),y(1:i),'+r');
    xlim([0 25]);
    ylim([-1.1 1.1]);
    %refreshdata(figure,'base')
    pause(0.001);
   % drawnow;
   delete(h)
end

How can I fix the problem ?

x = 1:0.01:25;
y = sin(x);
n = numel(x);
%figure;
for i = 1:n
    h=plot(x(i),y(i),'+r');
    xlim([0 25]);
    ylim([-1.1 1.1]);
    pause(0.001);
    delete(h)
end

Another computationally efficient approach is to create a single line object and update its XData and YData properties

x = 1:0.01:25;
y = sin(x);
n = numel(x);
%figure;
h = plot(nan, '+r');
xlim([0 25]);
ylim([-1.1 1.1]);
hold on
for i = 1:n
    h.XData = x(i);
    h.YData = y(i);
    %refreshdata(figure,'base')
    pause(0.001);
end
