I have designed a web service but need help designing one particular function. The current web service is at ws.historicaloptiondata.com.

I need to add a function that will return data for graphs.

Sometimes it will return 2 "columns" of data, and sometimes it could be 12 "columns" of data (or any number in between).

This is for a financial web site. A user may want to view 7 or 8 different technical studies, or just 1. All of them need to be linked together by date.

All of my functions up to now always return a fixed defined data structure with a known XML layout.

This function needs to take a variable number of inputs and output a variable amount of data. I need someone who has done this to point my design in the right direction.

Your job will be to write a page or so showing the best way to do this and list the best references on the web where I can read more about possible solutions.

I don't want to have one function per technical analysis study. I want them to be able to chose which ones they want, provide parameters for each algorithm and then have returned to them their results.

This is not a programming assignment for you, just a writing assignment for the design.
