public class ChartRenderer

extends DataWebBeanImpl

implements javax.servlet.http.HttpSessionBindingListener

Chart web bean to render chart as GIF files.

This bean renders the view as a chart GIF image. It internally uses Perspective bean to render the data as GIF. This bean is made is exposed through getChart() method.

Usage :

  <jsp:useBean   class="oracle.jbo.html.databeans.ChartRenderer id="c"  scope="request" >

  <%

     c.setReleaseApplicationResources(false);
     c.initialize(application,session, request,response,out,"package23_Package23Module.EmpView");

     c.getChart().setTitleString("Leading company Corp.");
     c.getChart().setSubtitleString("Employee Sales-Commision chart");
     c.getChart().setFootnoteString("Year-1999-2000");
     c.setMappingColumnNames("Sal,Comm"); // draw these column's
     c.setSeriesLabelColumnName("Ename"); // use this column as series label
     c.setImageWidth(600);
     c.setImageHeight(600);
     c.execute();
   %>

   </jsp:useBean>
