The hold state is on by default when you use pylab. To clear a figure you
use clf().
Here's a brief example:
from pylab import *
figure() # Not really needed, you could have typed plot right away, but here
you can set some nice features like the size
plot([1,2,3])
plot([2,1,2]) # Will
I had the same problem about figures that freeze using IDLE and
matplotlib but finally I manage to solve it with the help of Eric and
also a bit of luck.
Instead of using TkAgg I use WxAgg and it never hangs.
I use Idle -n and in the matplotlibrc set Interactive
I use all latest version of Numpy
I also had a problem matching matplotlib's mathfonts with my Beamer
(http://latex-beamer.sourceforge.net) presentation's Helvetica (or
sans-serif) mathfonts.
As LaTeX does not support Helvetica Math unless you buy it from
Micropress, I was curious as to how Till Tantau managed to implement
sans-se
Hi,
How can I use zoom for polar plots ?
I mean a circular cutout would be better than a rectangular cutout.
Nils
from scipy import *
from pylab import show, polar
def M(omega):
s = 1j*omega
return linalg.solve(s*identity(n)-A_0,A_1)*exp(-h_0*s)
A_0 = array(([0,1.],[-32,-2]))
A_1 = arra
I have experienced the same problem with IDLE.
It only works with -n, but then you lose the nice feature of 'starting
over'.
Does anybody know a fix so we can do both?
Thanks,
Mark

Yes, I tried using axis in both IDLE and IPython. IPython's redrew
the axis automatically whereas IDLE's did not.

I am posting this message to both numpy and matplotlib mailing lists
because the thread relates to both.

Actually, it's really only relevant to matplotlib.

Thanks.
And running w/pythonw does what it should :-).

Do you know how to fix this in IDLE (it must be using python as
opposed to pythonw somehow).
Thanks again for all your help,

I'm afraid that I don't know enough about IDLE to help you.

That's probably not it -- as of MacPython 2.4, pythonw ands python are
the same.

OK, now I'm confused:

Hi Chris, Robert, ...?,
I'm glad you reminded me to make sure the path was right, b/c this
time, I had forgotten to run the "Update Shell" command that came w/
MacPython2.4. This gave me:

Okay, what version of wxPython did you install? What version of wxPython is
actually imported (check wx.__version__)?
