There's a good example of such an overlay at:
http://zoonek2.free.fr/UNIX/48_R/03.html
Look for a chart called "Third moment (skewness)". The example shows
how to calculate dimensions and draw a vertical line segment overlaid
on the histogram. Although he isn't doing exactly what you're looking
for, the code could be easily modified for your use.
There's a lot of other good stuff there, as well.
Enjoy,
pcc
