Well that's great! (I should have at least tried making such a plot
before posting. Sorry.) How come I couldn't find it in the
documentation? I can't find anything about available linestyles. Am
I looking the wrong location? I am looking at users_guide_0.9.0.pdf
Thanks again,
Jeremy

If one creates a 1V RMS sine wave, e.g. with a peak value of 1.414 or<br>
peak-peak of 2.83, then computes psd, the resulting amplitude is around<br>
24 dB, yet classic theory dictates the answer ought to be 20 log(1) = 0
dB.<br>
This offset seems consistent across various frequencies/sample
rates/amplitudes.<br>
Can someone illuminate the amplitude scaling of the psd algorithm?<br>

Jeremy,
I ran across the answer to this last week while searching the list for 
info on datestr2num (both subjects happened to come up in the same 
exchange).

I am a recent switcher to matplotlib from gnuplot so please forgive me
if I post often.
I am currently looking to see if there is a similar matplotlib
plotting style like gnuplots "histeps". An example is:
http://gnuplot.sourceforge.net/demo_4.2/random.4.png
As I searched through the email list archives, it seemed like John was
looking at adding "steps" as a linestyle to matplotlib. The email is
a few years old
http://sourceforge.net/mailarchive/message.php?msg_id=4158CE19.3060601%40gemini.edu
I was wondering if anything came from this or if I need to figure out
something on my own.
Thanks in advance.

Hello,
When I create a graph, margin is too wide. How can I reduce this?
There is an example with this mail.
Thanks.

If you build from source, you should only need libpng and libfreetype2, in addition to Python and its headers. Agg is included in matplotlib's source distribution -- if you have a version of Agg installed elsewhere it won't be used. (The SVN trunk also requires Numpy). 
The ports spec is probably pulling in one or more GUI frameworks, and thus X11 stuff (which is probably not unreasonable for most users). It may make sense for those dependencies to be specified as "optional" somehow... but that's really a BSD packaging issue.
Cheers,
Mike

Hello matplotlib users!
I'm following a plotting turorial for the Pylons web framework[1] which
uses matplotlib (Agg backend). I tried installing matplotlib from the
ports collection on my FreeBSD web server, but it wants to install lots
of X11 related stuff. I don't want that, so I'm wondering if it's
possible to install and use matplotlib in a no-GUI environment.
Please Cc: me, as I'm not on the list. Thanks!
Erik
