by: Oldchatterman | last post by:

Hello, in an application I measure a lot of 2d coordinates (x,y) of a pattern. This pattern consists of a set of points on grid with fixed pitches in x and y direction. These coordinates all have a score for quality and are sorted on this score. What I want to do is to sort these coordinates first on x and define groups (regions) of x-coordinates that belong together. After this step I want to sort the different x-regions in y-regions.
