AFAIK, there is no method of sorting data in a chartWrapper object, but you can sort dataTable objects. Use AJAX to fetch your json and feed it to a dataTable, sort the dataTable, and pass it to your chartWrapper. See my example here: http://pastie.org/2284486
The parameters for sorting are described in the #sort method of the dataTable object: http://code.google.com/apis/chart/interactive/docs/reference.html#DataTable -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
