>The array you're getting back from 'GetHeartBeatData' looks as if it is in the wrong format - it's an array of objects rather than an array of data. To get data that can converted to the format expected by Google.visualization it should be something like:

"{\"d\":[ [\"Time\",\"db1\",\"db2\",\"db3\",\"db4\"],[\"1:00\",54,50,57,47],[\"2:00\",56,46,63,20]]}";

(assuming you want to pass header information in the first row)

using just MyArray.d returns "Not an Array" from Google Charts

Obviously I'm missing something that's probably very simple - all I need to do is call an SP that returns an array and get Google Charts to accept it, and do this on the client side.
