It would be nice if there was a way for the .swf to detect whether or not two values would collide. Obviously, one can change how a label or value is displayed (on top of or inside a bar chart, for example), or try to make the second axis values far away from the first, so that collisions don't happen IF one knows the data ahead of time. However, if the data generated is fairly dynamic in scope, and has a wide degree of variability, this is impossible.
If anyone knows of a way to better control value display to avoid collisions, please advise.
