I didn't know about QueryWrappers, but as they say, you learn something new every day. In your code, does queryWrapper1.currentDataTable contain a DataTable object?
Incidentally, ChartWrappers support a refresh interval to requery the data source for updates, and they're a bit neater to code than the QueryWrapper looks like (though, as I mentioned above, there is currently no way to directly access the underlying DataTable object of a ChartWrapper that uses a query). -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
