Very slowly in IE

<script type="text/javascript">
var myData = new Array();
for (var i = 0; i < 100; i++)
{
myData.push([i+"",i+10]);
}

//var colors = ['#AF0202', '#EC7A00', '#FCD200', '#81C714'];
var myChart = new JSChart('graph', 'bar');
myChart.setDataArray(myData);
//myChart.colorizeBars(colors);
myChart.setTitle('Year-to-year growth in home broadband penetration in U.S.');
myChart.setTitleColor('#8E8E8E');
myChart.setAxisName'');
myChart.setAxisNameY('%');
myChart.setAxisColor('#C4C4C4');
myChart.setAxisNameFontSize(16);
myChart.setAxisNameColor('#999');
myChart.setAxisValuesColor('#7E7E7E');
myChart.setBarValuesColor('#7E7E7E');
myChart.setAxisPaddingTop(60);
myChart.setAxisPaddingRight(140);
myChart.setAxisPaddingLeft(150);
myChart.setAxisPaddingBottom(40);
myChart.setTextPaddingLeft(105);
myChart.setTitleFontSize(11);
myChart.setBarBorderWidth(1);
myChart.setBarBorderColor('#C4C4C4');
myChart.setBarSpacingRatio(50);
myChart.setGrid(false);
myChart.setSize(616, 321);
myChart.setBackgroundImage('chart_bg.jpg');
myChart.draw();
</script>

Is there a way to improve the speed on IE? I am drawing a bar chart with 25 data points and it takes around 5 seconds to draw. On FF it is almost instantly.
Thanks.
