Say I have a random sequence of such as new=randn(5,1) which produces y values of
ans =
-0.9118
0.0494
1.0780
0.3082
0.2996
How would I plot these points as a line on a graph ie x=0, y=-0.9118 x=1 y=0.0494 etc or a line connecting the y values. I have tried
plot(new)
I would then like to add points to the graph as blue dots ie onto the graph of new=randn(5,1) add blue dots at the points from code such as
datapoints=
-0.9118
0.3082 or
datapoints=-0.9118 0.3082
I hope this make sense and thanks for the help.

I suggest you to check hold on, and the LineSpec of the command plot
% your data
new = rand(5,1);
% open figure and retain current plot
figure, hold on
plot(new);
% new data points
datapoints = [-0.9118 0.3082]
% plot with blue circles
plot(datapoints,'bo')
