Hi Tom,

You might want to look at Bob Nelson's software repository:

(This is linked from the AAVSO software page also.)

I think the Phases spreadsheet will give you a pseudo grahical representation of the way lightcurve phases progress over a user specified period of time given a set of elements. (I hope I'm remembering this correctly.) I don't know if that's what you need but you can take a look. Some of the other programs there are pretty good too.
