Showing a graph where data comes from a web service

Hi Forum,

I am a beginner in xMII and my requirement is to show a graph which gets data from a web service call. I am now able to get the data using data server and am able to build a graph.

But i couldn't find any information on how to consume data from a web service rather using a data server.

If you feel this is a very basic question send me some links. I tried to find but couldn't find any thing related to this.

Thanks,

Michael.
