gg, I suggest you take a look at R. It's a rather daunting programming environment for statistics and graphing. However, there are several graphical UIs for it, including one which works as an add-on for Excel. This should allow you to get started without wasting too much time learning new things. OTOH, if you have enough time left before your deadline, it's probably worth learning to use R from the command line. |
