I have a:
var wrapper2 = new google.visualization.ChartWrapper({
....
dataSourceUrl: dataSourceURL,
query: 'select month(A), count(G) where G = \'USER_LOGIN\'
group by
month(A) pivot I order by month(A)',
containerId: 'chart_div2'
...});
that fails when there is no data in the spreadsheet.
I've setup:
google.visualization.events.addListener(wrapper2, 'error',
errorHandler);
But this listener is called after there is an error message in the
chart_div2
Is there a way to do a handleQueryResponse and check for error on a
ChartWrapper so I can intercept the error generation?
