Hi all,
I m using BIRT chart from a week now.
i want to create chart in my web application by using stand alone chart engine api
I)I got one solution is that BIRT provides jsp tag liabry for creating a chart on aweb.
But it required a input as XML file which creates chart.
II)and another solution is use of servlet and jsp and xml file
to create chart.
In frist solution its working fine but it is difficult for me to create xml file for different chart types such as stackedbar chart, line chart,Area chart etc
Is any body provide me the sample example of it
i realy needed it.........Pleas
and in another solution in which i use servlet
I got the erroe as
