I am trying to build a tool where I have plotted 2D points in a graph using

scatter(X,Y,ptSz,'r','filled');

I would like to examine the spread of points over the 2D area by placing 1mx1m box across the acrea and computing the number of points in each box. I would like to know which box has least and most amount of points. I would also like to compute the average number of points in the boxes.

Eventually it would be effective to color map the boxes, representing the density of points.
