MATLAB: How to plot data point by point and erasing the last one

elseiffigureplotscatter

Hello, I need to plot my data point by point, but I also need just one point on the plot (when new point arrived the one before to disappear). That is my code everything works good I just want to fix that:
y=[1,3,2,3,3];
n=numel(y)
figure 
xlim([0 2])
ylim([0 2])
grid on
hold on
for ii=1:n
    if y(ii)<1.1
    scatter(0.5,0.5),hold on
    pause(1)
    else if y(ii)<2.2
    scatter(1.5,1.5),hold on
        else
    scatter(0.5,1.5)
    pause(1)
        end
    end
end

I have done pretty much animated plot with Matlab, What you need is a little trick !!
y=[1,3,2,3,3];
n=numel(y)
figure 
xlim([0 2])
ylim([0 2])
grid on
hold on
for ii=1:n
    if y(ii)<1.1
    scatter(0.5,0.5)  ,hold on
    pause(1)
    scatter(0.5,0.5,'w')  ,hold on
    else if y(ii)<2.2
    scatter(1.5,1.5) ,hold on
    pause(1)
    scatter(1.5,1.5, 'w') ,hold on
        else
    scatter(0.5,1.5)
    pause(1)
    scatter(0.5,1.5,'w')
        end
    end
end
