I don't know how to use getHtmlDataEx API ...

ChartSmaple.jsp

  <IMG SRC="/jsp/fundmall/chart/common/chart_cmmf503.jsp?Gigan=12&Gdcd=11111" >

AND

chart_cmmf503.jsp

response.setContentType("image/x-png");

  ....................

  .....................

  chart.getTitles().getItem(0).setText("GijunGa");

 chart.recalcScale();

 

 ServletOutputStream outStream = response.getOutputStream();

 chart.getHtmlDataEx("400","200","PNG", outStream,outStream,outStream);
