生成两组数据填充到 图形里面就可以哦， freechart 官网上面有事例的， 亲。。看下帮助， 给你 xml 的事例给你

<script type="text/javascript">
		   var chart = new FusionCharts("../Charts/MSColumnLine3D.swf", "ChartId", "600", "300", "0", "0");
		   chart.setDataURL("Data/Col3DLine.xml");		   
		   chart.render("chartdiv");
		</script>

<chart caption='Company Revenue' palette='1' showValues='0' yAxisValuesPadding='10'>
