I assume you want to add a point to the graph iteration wise.
 
In that case, try this -
 
%Sample values
density = rand(1,10);

%Initialize an animated line with specifications as needed
h = animatedline('Marker', '*');

for idx = 1:10
    %Add points to the line
    addpoints(h, idx, density(idx))
    %Update the figure
    drawnow
end
