Hi Mitra,
I understand that you want to label some points in a plot. You can label the points using “text” function. Below is an example where some points are labelled with their corresponding y-value.
x = linspace(0,3*pi,10);
y = cos(x) + rand(1,10);
scatter(x,y)
text(x(1,2),y(1,2),string(y(1,2)));
text(x(1,6),y(1,6),string(y(1,6)));
text(x(1,9),y(1,9),string(y(1,9)));
To know more about “text” function, please refer to the following MATLAB documentation:
