google chart demo:
var data = google.visualization.arrayToDataTable([
['Month', 'Bolivia', 'Ecuador', 'Madagascar', 'Papua New Guinea', 'Rwanda', 'Average'],
['2004/05', 165, 938, 522, 998, 450, 614.6],
['2005/06', 135, 1120, 599, 1268, 288, 682],
['2006/07', 157, 1167, 587, 807, 397, 623],

['2008/09', 136, 691, 629, 1026, 366, 569.6]
]);
var options = {
title: 'Monthly Coffee Production by Country',
vAxis: { title: 'Cups' },
hAxis: { title: 'Month' },
seriesType: 'bars',
series: { 5: { type: 'line' } }
};
var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));
chart.draw(data, options);
