Log Message:	The chart data file name can also be specified within the configuration. The method used to submit the form may als obe configured - at this current moment in time, this should only really be set to either "POST" or "GET". GET sends the form with the parameters specified in the query string (at the end of the URL). POST sends them over HTTP without being displayed in the URL. We shall stay with the GET method for now - although it produces rather ugly, long URLs in the browser, they are on the other hand quite handy because you can then copy it and email the URL to somebody to show them are particular chart and say something like, "ooh, what happened to raptor there?"
