Thank you Riccardo That answers all my questions regarding serialization (to file).
I am still very confused about support of parameters as of now(). I am trying to milk as much goodness from the Areachart API that I can right now. So I have tried many of the configuration parameters listed in http://code.google.com/apis/chart/interactive/docs/gallery/areachart.html Most cause a failure to generate the image when used in html/js/json in a web page or cgi script. Is there a resource where we are able to lookup which of the paramters are currenlty supported and which not? This would save me the time of having to test each parameter manually. Or do they all work but I am just doing something wrong? Thanks a lot Riccardo. -- Eric Riccardo Govoni ☢ said: > I think there's a bit of confusion here.
