Thanks Eric for pointing out this. However i've found that psd and
specgram plot 10*log10*(Pxx/max(Pxx)), so i'll have a range from 0 db
down.
Anyway, what do you mean by "should not be axes method"?
Do you mean using the array output of specgram and psd and plotting that
result by myself?
Cheers

I've upgraded to python 2.6, install all packages I need for that version

Hello all,
I am a relatively new user of matplotlib but have come a long way in

parameters).

Animating a line plot is well covered in the Cookbook:

Can anyone offer a hint or two for animating a histogram?

Thank you for your response. Your response made me wonder how the script would
operate in a non-graphic environment--I had tested it on a login node but not
on a computing node. It appears that even though I have no need for any graphic
display, the modules I am loading expect to have it nonethe
You can use the "Agg" or "PDF" backends to run matplotlib without
display support:
import matplotlib
matplotlib.use("PDF")

Hi all,
I'm passing in "None" for the timezone in AutoDateFormatter.
What I am getting is "UTC", but what I want is nothing.
Looking at the code, I see lines like:

so my None is getting passed through. Then in DateFormatter, I see:

I'm used to the following definition of autocorrelation:

Does anyone know if there is a way to use ipython with the advantages of

I love ipython pylab mode, but like to use namespaces to keep things clean.

Hi,
basically I'm looking for something like 'waitfor' or 'uiwait' from the Matlab.
I want to achieve is the following behavior:
- show a figure with several subplot/images to the user
- let the user click on some stuff to get coordinates, handles, ...
- wait until the user has closed the window
