So I've been working with google charts for a while, but I want a
selecthandler when I click on a slice of my piechart. The 'ready' handler
does work, but the 'select' handler doesnt.
I hope you guys got an idea whats wrong with my code.
google.load("visualization", "1", {packages:["corechart", 'controls']});
var chart, data;
function ajax_pie_chart_call(data, limit) {
var data2 = google.visualization.arrayToDataTable(data);
// Define a slider control for the 'Donuts eaten' column
var slider = new google.visualization.ControlWrapper({
'controlType': 'NumberRangeFilter',
'containerId': 'control1',
'options': {
'filterColumnLabel': data[0][1],
'backgroundColor':'#ccc',
'ui': {'labelStacking': 'vertical'}
}
});
// Define a pie chart
var piechart = new google.visualization.ChartWrapper({
'chartType': 'PieChart',
'containerId': 'piechart',
'options': {
'backgroundColor': {'fill':'#f1f1f1', 'strokeWidth':0,
'stroke':'#f1f1f1'},
'width': '50%',
'height': 500,
'legend': 'right',
'chartArea': {'left': 15, 'top': 15, 'right': 0, 'bottom': 0},
'pieSliceText': 'value'
}
});
// $("#control1").show();
// Create the dashboard & Draw the chart
var chart = new
google.visualization.Dashboard(document.getElementById('piechart_total')).bind(slider,
piechart);
function selectHandler() {
alert('test');
}
google.visualization.events.addListener(chart, 'select',
selectHandler);
chart.draw(data2);
}
