> ipython does this, I believe, when you call it with the -pylab option, but
I have never tried it with a script.

the following script works on widnows

#test interactive matplotlib plotting
import threading
import numpy as np
import sys
import matplotlib
matplotlib.use('TkAgg')
import matplotlib.pylab as pyp
class MyThread(threading.Thread):
def __init__ (self, data, label):
self.data = data
self.label = label
threading.Thread.__init__ ( self )
def run(self):
pyp.plot(self.data)
pyp.xlabel('%s' % self.label)
pyp.show()
a = np.array([0, 4, 5, 5, 3, 4, 5])
MyThread(a,'first x label').start()
print ("please input x label")
input = sys.stdin.readline()
MyThread(a,input).start()
so basically abandoning interactive mode and running in a thread works. the
first show shows the plot which I can then interact with. After I input
from the keyboard the second plot updates the figure.
BUT
on mac I get the following errors
1) the figure window appears but has no content
2) after the keyboard input the xlabel updates and the figure content
displays and I get the following error
Exception in thread Thread-2:

I tried the backend macosx and the results were worse!! I'd rather use mac
if I can due to scikits.audiolab not installing in windows.
anyone shed any lights on the thread problem?
