Choices: scipy, matplot ...


I would like to do some real time signal processing with a graphical
display and I would like your advice as to what I should use. I would
like to be able to view the results and to change parameters of some
signal processing in 'real time'. Data is coming quite slowly in every
1-5 seconds and will consist of (x,y,t).
I have been thinking about SciPy or matplot, but am not restricting
myself to these (or even Python).

Thank you for any advice,

You will need:

- Python 25
- NumPy
- SciPy (possibly)
- Matplotlib (for graphing)
- PyGTK or wxPython (for the rest of the GUI)

Finally you need something to make Python talk to your hardware. Pick
one of the following, dependent on your need and skills:

- ctypes
- pyrex
- inlined C with scipy.weave
- autogenerated wrappers with swig
- hand-written Python extension in C
- hand-written Python extension in C++ (CXX or Boost.Python)

I installed SciPy and NumPy (0.9.5, because 0.9.6 does not work with the current version of SciPy), and had some teething troubles. I looked around for help and observed that the tutorial is dated October 2004, and is not as thorough as Python's documentation. Is there an alternative source of information that lists all the functions and their usage? I tried using scipy.info to get information on the std function in the stats libary,...
