If I use the following I get the right number row, but how do I sum of the
data
google.visualization.events.addListener(control, 'statechange',
function(event) {
var data2 = data.getFilteredRows([{column: 0, minValue:
control.getState().range.start, maxValue: control.getState().range.end}]);
document.getElementById('veight').value = data2.length;
});
