The method of showing part of a frame does not give felicitous results if, e.g, the plot of 1 - x^2 is to be done on domain from -1 to 1. If you open just about any calculus text, e.g., to a 2D graph plot, you'll see axes going through the pont (0, 0) and with that point labelled with a single 0. It's unfortunate that Mathematica does not provide an option to Plot to reproduce this well-established behavior. It's just plain annoying that one has to resort to the work-around of using an Epilog with a Text primitive. David Park wrote: > I'm a little surprised.
