Hi Andrew,
Thank you so much. I changed my code and it worked perfectly. But still I
am seeing another problem.
I have code to calculate total kbUsage for perticular MDN. That was working
before. But now it just gives total no of rows returned from the DB,
instead of total of all kbUsage.
var group = google.visualization.data.group(newData , [{
// we need a key column to group on, but since we want all rows
grouped into 1,
// then it needs a constant value
column: 2,
aggregation: google.visualization.data.sum,
type: 'number',
modifier: function () {
return 1;
}
}],
[{
// get the total of all KBUsage
column: 2, //instead of column 2, if i pass 0 (MDN) or (1) category, i
get the actual values of that column in my next alert.
label: 'Total Byte',
type: 'number',
aggregation: function (values) {
var product = 0;
var n = values.length;
for (i = 0; i < n; i++) {
//alert(values[i]); //This alert returns 1 everytime for column: 2,
instead of actual value
product = product + values[i];
}
return product;
}
}]);
document.getElementById('avg').innerHTML = group.getValue(0, 1);
Thanks
