Google Visualization API Geomap: How to handle marker click events?
- by Carlos da Costa
Hello. I initially have the Google Visualization API Geomap on a world view (options['dataMode'] = 'regions') and I capture the 'regionClick' event when a country is clicked like so:
google.visualization.events.addListener(
geomap, 'regionClick', function (e) {
var rowindex = data.getFilteredRows([{column: 0, value: e['region']}]);
var location = data.getValue(rowindex[0], 3);
location.href = "?ISO=" + e['region'] + "&Location=" + location;
});
I then draw the map zoomed into the country in markers mode (options['dataMode'] = 'markers'). However, I can't seem to capture any events when the markers themselves are clicked.
The documentation ( http://code.google.com/apis/visualization/documentation/gallery/geomap.html#Events ) only refers to 'select' and 'regionClick' events neither of which are fired in this case. (Tested using Chrome 9, and IE 8.)
Has anybody had any success in doing this?
Many thanks.
