jsp chart 能否一个chart上花几条线？

目前这样

HTML code:

<table border="0" cellpadding="0" cellspacing="0" width="100%" height='280' class='innerbarII'>
<tr><td align='center' valign='bottom'>
<img border=0 src="http://localhost:8084/servlet/com.objectplanet.chart.ChartServlet?chart=line&graphInsets=80,80,50,260&width=640&height=480&sampleValues=12,34,45,56,67,56,67&sampleLabels=one,two,three,four,five,six,seven,eight,nine,ten&sampleLabelsOn=true">
</td></tr>
</table>



但这样只能画一条折线，怎么才能在上面画多条折线？

在线等，谢谢
