Just make a Table of values and Write them to a file.  If your other 
graphing routine doesn't like all the curly braces and commas, turn each 
data point into a string with the correct format and WriteAppend each 
one in turn to the file.  You will probably have to play around with 
various file writing commands and string conversion routines for a half 
hour or so to get it right.
