I know with some more work VisAD can do > all these and more, but as it stands, the meat of VisAD is 3D. Please ignore this kind of stupid question and criticism of VisAD from such NEWBIE as M.Huang . Obviously, this is an insult to Bill and the VisAD team. If M.Huang cannot understand VisAD, then use JFreeChart or SGT. VisAD is for serious stuff (or at least scientific stuff) . Scientific computing is different from simple High School type plotting that is available in JFreeChart. If you do High School plot then VisAD is not for you. Try some commercial Java graphics APIs or any open source ones. VisAD is the best is there is for Java. I rate VisAD as the same par as MatLab graphics or in some functionalities it has more built-in graphics manipulation functions than MatLab. MatLab is almost the standard Tool of every University Engineering School, Industrial Research (eg, NASA), Physics and Maths Departments around the world. So if VisAD is equivalent to or almost superior than MatLab graphics, then this means that M. Huang, need to join the mail-group for JFreeChart or a newbie Java graphics mail-group and demand the functionalities that she/he needed to be implemented. Sione.
