Hmm. The AjaxData string looks odd. 'd' should be an array of arrays so would look like this (note the extra square brackets):

"{\"d\":[ [\"Time\",\"DB1\",\"DB2\",\"DB3\",\"DB4\"],[\"1:00\",54,50,57,47],[\"2:00\",56,46,63,20]]}"

var MyArray = Json.parse(AjaxData) on that would give you an object 'd' with three 'rows' - the first containing the column information and the other two holding data. So if you wanted to pass the whole thing to google visualization it would be:

google.Visualization.arrayToDataTable(MyArray.d,false);

(false indicates first row is header data). If you just wanted the first data row passed in then

google.Visualization.arrayToDataTable(MyArray.d[1]);
