Hi Arjun, I think Matplotlib would be the best choice taking in count that we probably want to work analysing bio-signals, i see that Matplotlib has splendid examples like
mri_with_eeg.py<http://matplotlib.sourceforge.net/screenshots/mri_with_eeg.py>and eeg.py <http://matplotlib.sourceforge.net/screenshots/eeg.py> So we have a nice framework to begin with. Also without knowing too much about it, the problem about the large size could be worked out as you suggested. cheers!
