With that many points don't think you'll have anything close to enough room to show 'em all, but it's a pretty trivial exercise--
x=[1:10].';y=randi(10,10,1); % make up some data
scatter(x,y) % scatterplot it
xlim([0 11]),ylim([0 11]) % put some space around the outside points
text(x+0.1,y,num2str([x y],'[%d,%d]')) % and label the points
I don't understand your location calculation but you should be able to figure out how to put the numbers you want where you want them from the above.
