The best book on point and figure charting is Alexander Wheelan Study Helps in Point and Figure Technique. It concentrates on the original form of point and figure charting which is called one box reversal charting. It is published by Fraser Publishing in Vermont USA. See www.fraserbooks.com. I think The Educated Investor bookshop in Collins Street Melbourne stocks it.
You have a problem with MetaStock, because it draws one box reversal point and figure charts wrongly. There is discussion of this on my web site under Ask Colin/Technical Analysis/Point and Figure and Ask Colin/Software.
The best books specifically on three box reversal charting are Dorsey Point and Figure Charting and Aby Point and figure Charting. I think I prefer them in that order.
