Hmm, using MySQL...You are aware that it supports High Level Graphing as of version 5.1? IMO I think your are overloading yourself in 
PHP Code. Why not let the DB do this for you since you already have some of the data in it? You could use SPROCS and 
Triggers to do this all. As in Plotting all your corordinates you need.
