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

parameters).

Animating a line plot is well covered in the Cookbook:

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

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:
