Show row and column number by the side of each point in scatterplot

Hi,

I have an array X of values has 741 (rows) and 1 (col). Y is also the same. I want to plot a scatterplot(X,Y) but I need to show row and col number by a side of each point (pair) in the scatterplot.

The formula to calculate row number = (741*2)/39 and col number = (741*2)/38

Can somebody help me with that please?

Thanks in advance.

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.
