[SciPy-user] Real-time plotting and data storage format questions

A small team of us are developing a new simulation package from the ground
up. Our legacy approach relied on MATLAB and other proprietary software. A
hope pf ours is to be able to shed the use of MATLAB for the analysis of our
simulation results and instead use python with scipy/numpy/matplotlib etc.
I've successfully installed and compiled optimized numpy/scipy and all the
supporting packages (ATLAS, FFTW, etc).

So far so good.

To the point - I have two questions:

1) We would like to have a "scope" to monitor simulation outputs in real
time. We're using one tool that can take data over a tcp/ip port, but is
clunky and only works on a single platform. Does such a thing exists within
the python realm for plotting data in real time?

2) Our simulation creates large (1-4 GB) data sets. Since we're writing this
simulation ourselves (C++) we can save the data in any format. Does anyone
have a suggestion for a specific format or API that's been found to be
optimal in terms of memory usage and ability to import into python for
analysis and plotting?

Thank you for any suggestions. We're still new with Python, so I apologize
if these questions seem mundane.
