Belinda -
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
Hi,
How can I use zoom for polar plots ?
I mean a circular cutout would be better than a rectangular cutout.

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 =
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,

belinda Hi,
belinda I've been playing w/both IDLE and IPython, using TkAgg in

Mark,

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

Actually, it's really only relevant to matplotlib.
However, after installing wx and matplotlib, various problems result:

Robert,

Do you know how to fix this in IDLE (it must be using python as
opposed to pythonw somehow).
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.
