Hi, Riccardo and Yolanda
I am hitting the similar issue .
I have a very very large array named " tmp" (the array contains about
2,700,000 elements )
The page hang then crash.
Would you please help me out , I am stuck at this for about 1 week :(
Would you mind if taking a look my codes ?
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
var tmp = [[,1],[,2],[,5] .................]; <==== It 's a
big array with about 2,700,000 elements
var rows = [];
data.addRows(tmp.length);
for (var i = 0; i < tmp.length; i++) {
data.setValue(i, 0, tmp[i][0]);
data.setValue(i, 1, tmp[i][1]);
}
