I have never used the Plot wizard.
All of the people i have heard talk about it say thit it is a wast of time to use it. It uses to many local vars and makes scripts that are hard to debug/upgrade if you ever need to mess with them. Since we have moved here to the social site I have only seen one other post on the plot wizard and the sugestion was made to them to not use it.
I would have to agree. Conversation if needed and write your own scripts. If you can not write your own scripts there are three script generatior out there that can help.
