a +1 shift overlaying lines/points on a boxplot (PR#398)

Full_Name: Adrian Custer
Version: 0.90.0
OS: Linux on Thinkpad (pentium) and desktop (K6)
Submission from: (NULL) (128.32.251.234)


When I create a boxplot, and then try to overlay a lowess fit or just the
points, 
the points do not appear in the highest level and the lowess curve does not
reach 
the highest level. However, if I add one to each of the models, the problem is
solved.
I tried this on two different machines, a laptop and a desktop both running 
Gnu/linux+gnome. If you can't reproduce this please let me know.  -adrian
