[jCharts-users] Re: Re: regarding jCharts Samples

[Nathaniel G. A. <nat...@ya...>]

I am not sure what you are asking.

The ChartServlet used in the demo code was just for that demo code and not intended to be part of
the core jcharts API.  You certainly can copy it from the demo and modify it to do whatever you
need.

Each chart on a page needs a separate request to the Server.  so you would need two or more <img>
tags.

Yes, the encode(...) methods return void.  Would you prefer them to return something?
