hi all,
i'm trying to find the function for the pdf of a multivariate normal pdf. i
know that multivariate_normal can be used to sample from the multivariate
normal distribution, but i just want to get the pdf for a given vector of
means and a covariance matrix. is there a function to do this?

I've written a python gui to matplotlib which allows the user to plot either
cartesian, semi-log, or log-log plots. Log plots can be generated for typical
base values except for base 2. Is this a bug, or is there some reason that
matplotlib does not do log plots using base 2?

Hi all,
I have just migrated from Matlab to Scipy. Matplotlib has been great so far.
However, I have some trouble getting imshow to behave like Matlab's image
function.
If you do image(eye(8)) in matlab, you get this:

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
Hi folks,
Does anyone know if there is a way to use ipython with the advantages of
the -pylab option (separate gui thread, etc.), but without the whole

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

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:

Well,
actually i'm using Ubuntu at work on a virtual machine, and the svn copy is
in a partition mounted at boot by a line in /etc/fstab.
If i remember correctly this filesystem is mounted with options users. I'm
at home now, i'll try with the exec option tomorrow.
Is anyone else having this problem? Is there another website that I can
try?

You can use the "Agg" or "PDF" backends to run matplotlib without
display support:

Animating a line plot is well covered in the Cookbook:
http://www.scipy.org/Cookbook/Matplotlib/Animations
Can anyone offer a hint or two for animating a histogram?

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?
