Unfortunately, even though this works, mathematicians really want arrows at each end of the graph. Easy enough to do with drawdblarrow P withcolor blue, but the arrows then get clipped. What I really need is to adapt the code below so that my function is clipped to the boundary box, but then redrawn with arrows at each end of it. If anyone can adjust my code to do that, it would be much appreciated, and it would break down a barrier I've faced for years with metapost coding.
Just for clarification: What would you do with a "mexican hat" (x^4-4*x^2+4, y between 0 and 3) it if would cut the boundary 4 times? Use 4 arrows or just the two at the end? Mojca
