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
