assign scatter points into each grid and show probability in colorbar

Asked by jason on 2 Apr 2013

hi everyone, I currently generated large amount of points, how can i divide the plane into many small grids and assign the points included as that specific grid, then show the probability of hitting the grids as different color with a colorbar next to the figure. so the result i am trying to get is different grid has different color showing the probability. thank you very much
