name a single point in a scatterplot

Hi, can anyone tell me how to name a single point in a scatterplot? I want to add name on the top of every dot to show that each dot represent different model. My data is a 2-d data. Thank you.

text() the string at the position of the point.

Your plot would probably be less crowded if you were to use different dot colors for the different models.

You may wish to consider using datacursormode() to allow the user to select a point and have the model name show up.

I tried to use text() but it only shows the value of my data which is number. What I need is insert name above the dots.

For example,

for K = 1 : length(x)

text(x(K),y(K), sprintf('Point #%d', K));

end

Sorry i am quite new in matlab.

If my x data is 11x1 double and y is 11 x 1 double. The name that i want to insert is : a e f s g j d e a f h. Can you show me how to use the loops that you shown?

Thank you.

names = {'a' 'e' 'f' 's' 'g' 'j' 'd' 'e' 'a' 'f' 'h'};

for K = 1 : length(x)

text(x(K), y(K), names{K});

end
