Computing point density in 1mx1m box placed across the graph

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.

histcounts2() does that.
It counts the density of (x,y) coordinates within each bin that you specify.
