Hi If you are using a data source (such as google spreadsheets) to create the data then you can use a query language<http://code.google.com/apis/visualization/documentation/querylanguage.html>to do that with a query string such as "select Channel,avg(Uptime) group by Channel". If you are creating your data table at the client side then there is no available api to do grouping but we are working on enabling this feature
