<ul><li>Hi, I'm trying to displaying Chart minimum , maximum and average values but I can't able to render output I'm always getting bellow error how to debug chart script ? </li>
<li>Can't find method org.eclipse.birt.chart.model.data.impl.NumberDataElementImpl.create(null)</li>
</ul><p>OnRender Chart Script Code :</p>
