    after some testings I found the reason of the bug: you defined a strings in data instead of numbers, fixed page below:

    <html>
<head>
<script type="text/javascript" 
src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
var jsonDataObj = {
"rows":[
{"c":[{"v":"2001"},{"v":65},{"v":40}]},
{"c":[{"v":"2002"},{"v":67},{"v":43}]},
{"c":[{"v":"2003"},{"v":80},{"v":35}]},
{"c":[{"v":"2004"},{"v":97},{"v":47}]}
],
"cols":[
{"id":"","label":"Year","type":"string"},
{"id":"","label":"profits","type":"number"}, 
{"id":"","label":"expenses","type":"number"}
]
};


function drawChart() {
var jsonData = jsonDataObj;
var data = new google.visualization.DataTable(jsonData);
var options = {
width: 800,
height: 480,
isStacked: true,
title: 'Company Performance'
};
var chart = new google.visualization.BarChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id="chart_div"></div>
</body>
</html>
