I stress again that if you insist on thinking of mathematica as a program rather than a programming language, you are in for a lot of disappointment and frustration. The Wolfram corporations marketing division is famous for exaggerating and mis-stating mathematicas capabilities. The advertising literature often sounds as if Mathematica is a program that is so convenient to use, but it is not. It is an interpreted object oriented programming language with a ton of built in subroutines for numerical, symbolic and graphing, but in many cases these are critically flawed in one way or another and one must resort to the core graphics language of mathemtica--graphics primitives. The real benefit to mathematica is that you can spend your time learning one core programming language rather than learning a dozen command line interfaces for niche programs like gnuplot and then still having to maintain proficiency in C++ or Fortran to get your technical computing done. I am replying to your comments only because I have seen so many mathematica beginners waste a lot of time expecting mathematica to be something it is not, usually being mislead by the advertising literature. Save yourself the time and frustration--adopt the mindset that this is a new programming language that just happens to have some limited graphing subroutines built in that will probably not have the particular options you are looking for and that you will have to program them in yourself. With this as your mindset, you will spend less time cursing Wolfram and more time solving your problem and learning the programming language. Wolfram doesn't put so much emphasis on GUI. The "frontend" is an extremely weak GUI and is, itself written in mathematica and C++. Mathematica is still, very much a command driven programming language. Having a notebook style front end hasn't really changed that central fact. As far as graphics in specific go, all the built in *Plot* functions convert a set of data into a SurfaceGraphics, or Graphics object in terms of graphics primitives. If you want an effect that is not built in, then haul out the primitives and do it yourself.
