I'm trying to make Mathematica draw custom error-bars for statistical data. The problem is that I can't figure out how to make Mathematica draw little lines for ticks at the confidence limits, etc. I want the *position* to be in application coordinates, but the length of the ticks to be in terms of the width of the plot. I figured if I could track down how Mathematica does axes, I'd be able to figure out what I want, but the axes code seems to be hidden from users. -- David Jacobson
