I am not exactly following you.  Are you looking for the program or do you already have the program and you need help in using it.  In any case, you can still download ChartThrob and get most of the info on how to implement it here:


This thread on the old dpug and now Photrio can be helpful too since that's where the method was first presented.


I have used the system myself recently. So if you have any specific question, feel free to ask here.
