Thanks, Herbert. That is a beautiful example, but it does not correspond to what I mean. I admit that it is my fault, as it seems that I was not clear enough. I will try to be clearer now. Imagine that you need to draw a circumference, and that you are given only a set of hundreds and hundreds of points (x,y) belonging to the circumference. Furthermore, suppose that you are unable to determine the circumference equation. My problem is similar to the one just described: I have hundreds of points in the form (x,y) that I want to display in an appropriate rectangle, along the same lines as one draws level curves. Is it now clear? Paul
