I have published this chapter, but if someone (PeterS, perhaps?) has the
time to replace some of the poorer-quality images, that would be great; I
could then replace the published file with the improved one. Most of the
figures needing replacement are screenshots of Calc dialogs.
This file has the tables and charts used for Chapter 3.
