But it takes like 30 minutes to plot, and using this one: just takes 30 secs but i dont want lines, i want points.
table = readtable('laser_data.csv');
array = table2array(table);
h = animatedline('Marker','none');
for i = 1:length(array)
%LEFT
for k = 2:2:30
x = -0.018+array(i,k);
y = 0.0899+array(i,k+1);
xlabel('Distancia en el eje X')
ylabel('Distancia en el eje Y')
title('Obstáculos')
addpoints(h,x,y)
drawnow limitrate
%pause(0.00001)
end
%FRONT
for k = 32:2:60
x = 0.05620-array(i,k+1);
y = array(i,k);
xlabel('Distancia en el eje X')
ylabel('Distancia en el eje Y')
title('Obstáculos')
addpoints(h,x,y)
drawnow limitrate
%pause(0.00001)
end
%RIGHT
for k = 62:2:90
x = 0.018-array(i,k);
y = -0.0899-array(i,k+1);
xlabel('Distancia en el eje X')
ylabel('Distancia en el eje Y')
title('Obstáculos')
addpoints(h,x,y)
drawnow limitrate
% pause(0.00001)
end
end

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')

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...
