The important view for the drilldown is this one:
google.visualization.events.addListener(chart, 'select', function () {
var sel = chart.getChart().getSelection();
var country = data.getValue(sel[0].row, 0);
var rows = data2.getFilteredRows([{column: 0, value: country}]);
var view = chart2.getView();
view.rows = rows;
chart2.setView(view);
chart2.draw();
});
and the only requirement here is that the drilldown and filtering happens
on column 0 in both DataTables (and you can change that to be a different
column, if necessary). Whether the data is dynamic or not is irrelevant.
