This should get you started for some code to connect to something like thingspeak. I haven't made time to go back and work on it for a bit. hopefully you understand it okay though:
I was trying to setup each function as a seperate function, then call each function as required. so for example if I wanted to publish 2 different lots of results to Thinkspeak seperatly I could. But it seems to have some issues in returning the correct content at times. Anyway have a play with it, it's a start for you.
Cheers
