Hi,
The Gauge chart actually doesn't have support for either the getSelection()
method nor the 'select' event. However, since you are only rendering one
gauge chart at any given time, you don't really need to know what to
render, since your DataTable will only have one row. So instead of
listening for the 'select', you can just listen for the click event on the
chart container. For some reason, jsfiddle won't let me post this code, but
here's a snippet of what you need to write:
document.getElementById('gauge1').addEventListener('click', function () {
// selection is an array of objects with {row, column} properties,
// use them to get data from your DataTable if you need to, ie:
var selectedValue = gauge1.getDataTable().getValue(0, 1);
// you can then emulate clicking a link from here
alert('You clicked on ' + selectedValue );
window.location.href = "http://www.google.com/";;
});
