Hi, that's not the correct way to load CSV files with Query. There is
currently no documentation for it, but we're working on it. For now, you
can use this
thread<https://groups.google.com/d/topic/google-visualization-api/8Ussi3X1fdA/discussion>as
a reference. Here is the snippet I posted in that thread as an
example:
var queryOptions = {
csvColumns: ['number', 'number' /* Or whatever the columns in the
CSV file are */],
csvHasHeader: true /* This should be false if your CSV file doesn't
have a header */
}
var query = new google.visualization.Query(csvUrl, queryOptions);
query.send(handleQueryResponse);
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' +
response.getDetailedMessage());
return;
}
var data = response.getDataTable();
// Draw your chart with the data table here.
}
