Re: [matplotlib-devel] Introduction

Hi,
I'll do these patches a little at a time.

Here is a patch to show a complex spectrogram with the negative frequencies
flipped down.  I've also attached a modified version of the
spectrogram_demo.py that creates the two signals as complex exponentials so
they are only in one half of the spectrum (long signal positive, short
signal negative).

Basically, if the input signal is complex then the whole spectrogram is
shown.  If the input is real then just the positive frequencies are shown.

Next I'll work on the following as discussed.
Thanks
Greg
