how to add new data to graph plotted by addpoints

Hi,

I am using addpoints to plots a graph that changes over time. I want to be able to plot the change mean of the graph, meaning in each iteration to plot a line of the current mean (without deleting the the graph values) how can this be done?

this is my code:

t=1:10;
y=@(t) t;

f=figure('Name','live data');
ax=axes('Parent',f)
h = animatedline('Marker','o','Parent',ax);

figure;
for i=1:10
    addpoints(h,i,y(i));
    pause(1);
end
