You cannot use a chart's "ready" event handler to draw the chart - it will
loop infinitely (draw -> ready -> draw -> ready, ad infinitum). Use a
"ready" event handler for another chart hooked up to the same filters
instead, and remove Chart1 from your Dashboard binding:
// assumes Chart2 is bound to the same filters you want Chart1 to use
google.visualization.events.addListener(Chart2, 'ready', function () {
var dt = Chart2.getDataTable();
var filterView1 = new google.visualization.DataView(dt);
filterView1.setRows(dt.getFilteredRows([{'column': 3, 'value':
'City/Town/Place*'}]));
var view1 = new google.visualization.DataView(filterView1);
view1.setRows(filterView1.getSortedRows(36));
Chart1.setDataTable(view1);
Chart1.draw();
}
If you don't have another chart that uses the same filters, you can insert
an intermediate chart to serve the purpose; just hide this chart's
container div and the user will not know the difference. I typically use a
Table visualization for this, with the rows limited to 1 to keep the impact
of the Table on the page performance down:
var dummyTable = new google.visualization.ChartWrapper({
chartType: 'Table',
containerId: 'dummy_table_div',
view: {
rows: [0]
}
});
