Hey guys,
I'm showing 3 small charts - pie, colum and geo on the same page. Here
is my code:
 <script src="
https://www.google.com/jsapi" type="text/javascript"></
script>
  <script type="text/javascript">
	google.load("visualization", "1", {packages:["corechart", 'geochart',
'imagechart']});
	google.setOnLoadCallback(drawPie);
	google.setOnLoadCallback(drawColumn);
	google.setOnLoadCallback(drawMap);
	function drawPie() {
		var age = [{"count":"2","age":"24"},{"count":"1","age":"30"},
{"count":"1","age":"40"}];
		var data = new google.visualization.DataTable();
		data.addColumn('string', 'Age');
		data.addColumn('number', 'Number of people');
		data.addRows(age.length);
		var i = 0;
		age.each(function(user) {
			data.setValue(i, 0, user.age.toString());
			data.setValue(i, 1, user.count.toInt());
			i++;
		});
		var chart = new
google.visualization.PieChart(document.getElementById('age'));
		chart.draw(data, {width: 450, height: 300, title: 'Age'});
		google.visualization.events.addListener(chart, 'select', function()
{
			var selection = chart.getSelection();
			var age = data.getValue(selection[0].row,0);
			window.location = 'index.php?
option=com_rapleaf&view=users&search=age:' + age;
		});
//		var options = {cht: 'p', title: 'Age', chp: 0.628, chs:
'400x200'};
//		var chart = new
google.visualization.ImageChart(document.getElementById('pie_div'));
//        chart.draw(data, options);
	}
	function drawColumn() {
		var gender = [{"age":24,"male":"1","female":"1"},{"age":
30,"male":"1","female":0},{"age":40,"male":0,"female":"1"}];
		var data = new google.visualization.DataTable();
		data.addColumn('string', 'Age');
		data.addColumn('number', 'Male');
		data.addColumn('number', 'Female');
		data.addRows(gender.length);
		var i = 0;
		gender.each(function(user) {
			data.setValue(i, 0, user.age.toString());
			data.setValue(i, 1, user.male.toInt());
			data.setValue(i, 2, user.female.toInt());
			i++;
		});
		var genderChart = new
google.visualization.ColumnChart(document.getElementById('gender'));
		genderChart.draw(data, {width: 450, height: 300, title: 'Gender',
					hAxis: {title: 'Age', titleTextStyle: {color: 'red'}}});
		google.visualization.events.addListener(genderChart, 'select',
function() {
			var selection = genderChart.getSelection();
			var gender = data.getValue(selection[0].row,0);
			window.location = 'index.php?
option=com_rapleaf&view=users&search=gender:' + gender;
		});
	}
	function drawMap() {
		var location = [{"count":"1","location":"Germany"},
{"count":"1","location":"Paris, France"},
{"count":"2","location":"Spain"}];
		var mapData = new google.visualization.DataTable();
		mapData.addColumn('string', 'Country');
		mapData.addColumn('number', 'Users');
		mapData.addRows(location.length);
		var i = 0;
		location.each(function(country) {
			mapData.setValue(i, 0, country.location);
			mapData.setValue(i, 1, country.count.toInt());
			i++;
		});
		var options = {width: 556, height: 347};
		var container = document.getElementById('map');
		var geochart = new google.visualization.GeoChart(container);
		geochart.draw(mapData, options);
		google.visualization.events.addListener(geochart, 'select',
function() {
//			var selection = geochart.getSelection();
//			var location = mapData.getValue(selection[0].row,0);
//			window.location = 'index.php?
option=com_rapleaf&view=users&search=location:' + location;
		});
	}
  </script>
The charts are displayed, but the pie and column one are missing the
tooltips. Moreover I have a listener for select, but it also doesn't
work.
When I remove the geoChart, then I get the expected result from the
pie and column charts...
Any ideas what am I doing wrong here?
