Hi, ok i have found my mistake..
i must use the JsonRenderer "JsonRenderer.renderDataTable(data, true, true, true)" and then i can use on the Client side "var data= new google.visualization.DataTable(json)". But how can i parse a csv on the server side to a DataTable ? i have the following csv: date,New York,San Francisco,Austin > 20111001,63.4,62.7,72.2 > 20111002,58.0,59.9,67.7 > 20111003,53.3,59.1,69.4 > 20111004,70.0,80.0,90.0 > and if the dataTable is created on server side can i change then the date Colum to a Date Object ?
