Folks, I need your help. I'll explain a little further what happens.
Following is a test program,'test.py', and screen shot of the error
message. Here, 'test.py' is simple chart of sinusoidal function in
http://matplotlib.sourceforge.net/screenshots.html (simple_plot.py), but
have two of them in series. I tried Wolfgang's suggestion but it doesn't
help. Any idea?
Test.py:
from pylab import *
t = arange(0.0, 2.0, 0.01)
s = sin(2*pi*t)
plot(t, s, linewidth=1.0)
xlabel('time (s)')
ylabel('voltage (mV)')
title('About as simple as it gets, folks')
grid(True)
show()
clf()
t = arange(0.0, 2.0, 0.01)
s = sin(2*pi*t)
plot(t, s, linewidth=1.0)
xlabel('time (s)')
ylabel('voltage (mV)')
title('About as simple as it gets, folks')
grid(True)
show()
Execution of test.py:
c:\Python24>python test.py
c:\Python24\lib\site-packages\matplotlib\numerix\__init__.py:53:
DeprecationWarn
ing: numarray use as a numerix backed for matplotlib is deprecated

This might help you it destroys the whole window:
pylab.get_current_fig_manager().destroy()
and then you open it again with show

Hi,
I 'm writing a python program that draws figures one by one
interactively with the user's input in dos mode. Basically, I give the
program a decision after each figure and then it draws the next one.
After the first figure, it got very much slowed down for the second
one and crashed for the third one. I feel like it has some memory
issues as I keep using 'show' after I close each. I used 'clf()'
before I draw a new one, but it doesn't seem to help. Any idea?
Thanks.
