Add numbers in a plot

I have 10 points with x and y coordinates, and I am plotting circles that center in these coordinates. I need to add the numbers 1 to 20 on each circle. How can I do this? So each circle has a number on it in my figure. x=[3,5,8,6,1,2,4,5,7,9] y=[5,4,3,1,7,8,6,5,9,0] so I will have 10 circles.

What does "circles that center in these coordinates" mean?
What do you expect as result of "adding 20 to a circle"? A circle is a geometric object, but 20 is a number.
How can a circle have a number on it? Do you want to insert text labels to the lines, e.g. as in contour plots (link)?
Please edit the question and try to be more clear.

Assuming you know how to plot circles, you could use text command right after you plot the circle,
text(x,y,['(',num2str(x),',',num2str(y),')']) %for ex: x = 3, y = 5 (scalars)
