I need to plot a Dynamic scattered plot. I have vector x and y, and those are coordinates. I need to plot coordinate 1, and then coordinate 2 but coordinate 1 must need to still there.

h = animatedline('Marker','none');

There's your problem...

 

array=readmatrix('laser_data.csv');             % no point in a table to just convert to array...
hAL=animatedline('Marker','.','MarkerSize',3,'LineStyle','none');  % set a point marker, no line...
xlabel('Distancia en el eje X')                 % don't update static info every pass through loop
ylabel('Distancia en el eje Y')
title('Obstáculos')
for i=1:size(array,1)                           % length() is risky
  %LEFT
  for k = 2:2:30
    x = -0.018+array(i,k);
    y = 0.0899+array(i,k+1);
    addpoints(hAL,x,y)
    drawnow limitrate
    %pause(0.00001)
  end
  ...

Make same changes in rest. It would be better to factor code so don't have repeated identical loops with just constants changing between, but that's another exercise...
